Where We Serve.

Eureka · Arcata · Fortuna · McKinleyville · Ferndale

Humboldt County has one of the highest opioid overdose death rates in California (California Department of Public Health, n.d.) and ranks among the top counties for suicide rates. The county has approximately 135,000 residents spread across 3,568 square miles (SimpleMapLab, n.d.), and outpatient mental health provider capacity has not kept pace with need. The result is a crisis in access that has persisted for years.

PMHS serves Humboldt County PHP members across all communities, including remote coastal and inland areas where driving to Eureka is not realistic. We offer evening and weekend appointments, which is essential in a county where many residents work in fishing, logging, and agriculture. If you have PHP through Medi-Cal, there is no cost, no referral, and no waitlist to navigate. Most patients complete their intake session within the same week they reach out.

Yreka · Mount Shasta · Weed · Dunsmuir · Etna · Montague

Siskiyou County spans 6,278 square miles with a population of roughly 42,000 (SimpleMapLab, n.d.) — one of the lowest population densities in California. The county has been designated a Mental Health Professional Shortage Area by the federal Health Resources and Services Administration (Health Resources and Services Administration, n.d.). The nearest psychiatric facility to much of the county is over 90 miles away in Redding.

PMHS clinicians understand the rural stress patterns common in Siskiyou County — agricultural pressures, economic uncertainty, seasonal isolation, and the mental health toll of wildfire proximity. We welcome veterans, who make up a significant share of the Siskiyou County population. PHP covers sessions at no cost, and for residents of remote communities like Etna, Fort Jones, or Happy Camp, telehealth is the most accessible option available.

Weaverville · Hayfork · Lewiston · Trinity Center · Hyampom

Trinity County has a population of approximately 15,700 spread across 3,179 square miles of mountainous terrain (SimpleMapLab, n.d.). The county has no psychiatric hospital, no inpatient mental health facility, and almost no contracted outpatient behavioral health providers. When Trinity County residents need mental health support, the only options are a long drive or telehealth.

The Trinity River watershed communities — Weaverville, Lewiston, and Trinity Center — are particularly isolated. Many residents have no reliable broadband, but sessions via phone audio are fully covered by PHP and available through PMHS when video is not possible. Like many rural Northern California counties, Trinity sees a meaningful share of patients dealing with substance use alongside their mental health concerns, and co-occurring presentations are common. PHP covers treatment for both, and most patients are scheduled within the same week they reach out.

Redding · Anderson · Shasta Lake · Cottonwood · Palo Cedro · Burney

Shasta County is home to roughly 172,000 people spread across 3,775 square miles (SimpleMapLab, n.d.) and is the largest urban center in the North State region. Despite having more infrastructure than its neighboring counties, Shasta faces a well-documented behavioral health workforce shortage. The county's rate of suicide is consistently above the California average (Shasta County Public Health, n.d.), and emergency department visits for mental health crises have increased significantly since 2020.

Outside of Redding, communities like Burney, Fall River Mills, and Igo-Ono have essentially no local mental health access. PMHS serves all of Shasta County, including its most remote precincts. Appointments are available evenings and weekends to accommodate work schedules in a county where shift work is common. PHP covers sessions at no cost and no referral from your primary care doctor is required.

Ukiah · Fort Bragg · Willits · Mendocino · Point Arena · Covelo

Mendocino County has approximately 90,000 residents spread across 3,506 square miles (SimpleMapLab, n.d.) and is part of California's Emerald Triangle, the state's best-known cannabis-growing region alongside Humboldt and Trinity counties (Smith, 2024), and has a significant population of unhoused residents, both of which correlate with elevated rates of co-occurring mental health and substance use disorders. The county has also historically had one of the highest rates of premature death from drug overdose in the state, though recent local data shows a marked decline (KZYX, 2025). Local behavioral health resources are concentrated in Ukiah, leaving coastal and inland communities severely underserved.

Fort Bragg is the county's second-largest city with roughly 7,000 residents and limited local mental health options. Covelo and the Round Valley region are particularly isolated. PMHS provides services across all of Mendocino County via secure video, including audio-only sessions for patients with limited internet access. PHP covers your sessions at no cost and no referral is required to get started.

Lakeport · Clearlake · Clearlake Oaks · Middletown · Lucerne · Kelseyville

Lake County has approximately 68,000 residents spread across 1,256 square miles (SimpleMapLab, n.d.) and consistently ranks among the three most economically distressed counties in California by unemployment rate, poverty rate, and median household income. It also has some of the highest rates of substance use disorder in the state, including the highest overdose death rate of any California county as of the most recent data (USAFacts, n.d.). The 2015 and 2018 wildfires displaced thousands of residents and left lasting trauma that the county's behavioral health system was not equipped to absorb.

Clear Lake — the largest natural freshwater lake in California — is central to the county's identity, but the communities around it are among the most underserved in Northern California. Clearlake, the county's largest city, has high rates of poverty and a predominantly Medi-Cal-enrolled population. PMHS serves Clearlake, Lakeport, Clearlake Oaks, and all surrounding communities.

Susanville · Herlong · Janesville · Bieber · Likely · Wendel

Lassen County sits at the intersection of the Great Basin desert and the Sierra Nevada, spanning 4,541 square miles (SimpleMapLab, n.d.). Its 33,000 residents live in one of the most geographically isolated counties in California. Susanville, the county seat, hosts High Desert State Prison, along with the nearby Federal Correctional Institution at Herlong (California Correctional Center, the county's other state prison, closed permanently in 2023 (California Correctional Center, n.d.)), which means a significant share of the county's population is either incarcerated or made up of families of incarcerated people, both of which carry distinct mental health needs.

Lassen County has been a federally designated Mental Health Professional Shortage Area for more than a decade (Health Resources and Services Administration, n.d.). Access to any specialty health care requires driving to Reno, Nevada or Redding — both over 90 miles away on mountain highways. Telehealth through PMHS eliminates that barrier entirely. Audio-only sessions are also available for patients in areas with poor internet connectivity, and PHP covers all sessions at no cost.

Alturas · Cedarville · Tulelake · Canby · Likely

Modoc County is one of California's least populous counties (U.S. Census Bureau, 2025), with approximately 9,600 residents spread across 3,918 square miles (SimpleMapLab, n.d.). Its only hospital, Modoc Medical Center in Alturas, is a small critical access facility with no inpatient psychiatric unit, so the nearest full behavioral health hospitalization is roughly 150 miles away in Redding. Behavioral health services in Modoc County are almost entirely absent, with fewer than five licensed mental health clinicians serving the entire county.

The Native American community in Modoc County, including members of the Pit River Tribe, faces compounding disadvantages in mental health access, alongside historical trauma, geographic isolation, and cultural barriers to traditional Western mental health services. PMHS takes an individualized approach that respects each patient's values and lived experience. PHP covers all sessions at no cost and no referral is required. Agricultural and ranching families in Modoc County's eastern communities face distinct stressors including drought, commodity price volatility, and the psychological weight of economic uncertainty.

Crescent City · Smith River · Klamath · Gasquet · Fort Dick

Del Norte County occupies the far northwestern corner of California, spanning 1,006 square miles bordered by the Pacific Ocean, the Oregon state line, and the Klamath River (SimpleMapLab, n.d.). Its 27,000 residents are among the most geographically isolated in the state. The county has one of the highest rates of suicide in California and virtually no local outpatient mental health infrastructure outside of Crescent City.

The Yurok Tribe, headquartered in Klamath, is the largest federally recognized tribe in California by population (U.S. Fish and Wildlife Service, 2023) and faces significant historical trauma, substance use, and mental health disparities. PMHS takes an individualized approach grounded in each patient's values and lived experience. PHP covers sessions at no cost and no referral or member card is required. Telephone-only sessions are available for patients without reliable internet access, and seasonal affective disorder is particularly prevalent due to low winter light levels along the northern coast.

Napa · American Canyon · Calistoga · St. Helena · Yountville · Angwin

Napa County has approximately 128,000 residents across 748 square miles (SimpleMapLab, n.d.) and is one of the wealthiest counties in California by median household income (PropertyClub, 2024), yet its mental health infrastructure tells a different story. The county has a significant population of agricultural workers — many employed in vineyards and wineries — who are largely Medi-Cal-enrolled, Spanish-speaking, and face significant barriers to mental health care including language, cost, and fear of immigration enforcement.

The wine industry also generates high rates of alcohol use disorder among workers and management alike, and Napa County's behavioral health system has documented gaps in treating co-occurring substance use and mental health conditions. Despite the county's wealth, contracted PHP outpatient providers with availability are consistently hard to find. PMHS accepts PHP directly, requires no referral, and offers same-week availability to all Napa County members.

Fairfield · Vacaville · Vallejo · Benicia · Dixon · Rio Vista · Suisun City

Solano County is home to roughly 450,000 residents across 822 square miles (SimpleMapLab, n.d.) and sits at the crossroads of the Bay Area and the Sacramento Valley. It has a large active-duty and veteran population due to Travis Air Force Base in Fairfield — one of the busiest air mobility wings in the U.S. Air Force (Travis Air Force Base, n.d.). Veterans and active-duty service members experience high rates of PTSD, depression, and adjustment disorders, and civilian mental health providers with military cultural competency are rare.

Vallejo, the county's largest city, has faced significant economic challenges since the city's 2008 bankruptcy. Rates of community violence exposure, poverty-related stress, and unmet mental health need are among the highest in the county. PHP-enrolled residents in Vallejo routinely report difficulty finding contracted providers with same-week availability. PMHS serves all of Solano County with no waitlist and same-week scheduling as standard.

Woodland · Davis · West Sacramento · Winters · Esparto · Clarksburg

Yolo County has approximately 223,000 residents across 1,015 square miles (SimpleMapLab, n.d.) and is home to the University of California, Davis, which means a significant portion of the county's young adult population is navigating academic pressure, identity development, financial stress, and social disconnection. UC Davis students on Medi-Cal may qualify for PHP coverage depending on their enrollment status. Yolo County also has a large migrant agricultural worker population, particularly in the rural western portion of the county.

Woodland, the county seat, has documented gaps in outpatient behavioral health access for its 61,000 residents. West Sacramento has a high concentration of unhoused residents and significant mental health need that is largely unmet by the existing system. PMHS serves all of Yolo County including its most rural communities. Appointments are available during evenings and weekends to accommodate both student and agricultural work schedules, and PHP covers all sessions at no cost with no referral required.

Red Bluff · Corning · Tehama · Los Molinos · Gerber · Flournoy

Tehama County is an agricultural valley county of approximately 73,000 residents spread across 2,950 square miles, centered on the Sacramento River corridor (SimpleMapLab, n.d.). The county has one of the highest rates of domestic violence-related emergency calls in Northern California (North State Parent, 2022), and intimate partner violence is consistently identified as a top behavioral health concern by the county's health department. The county also has elevated rates of methamphetamine use and alcohol use disorder.

Red Bluff, the county seat, has limited outpatient mental health capacity relative to need. Rural communities like Flournoy, Vina, and Rancho Tehama have no local options whatsoever. Tehama County residents also face long wait times for county-operated behavioral health services, often stretching three to six months for a first appointment. PMHS offers same-week availability with no referral required and PHP covers all sessions at no cost. Telephone-only sessions are available for patients with limited internet access, and PHP covers both video and audio formats.

Willows · Orland · Hamilton City · Elk Creek · Artois

Glenn County has a population of approximately 29,600 spread across 1,314 square miles (SimpleMapLab, n.d.) and is one of the smallest and most rural counties in California by population. It is almost entirely agricultural, with rice, almonds, walnuts, and cattle defining the local economy. The county has no psychiatric services and no inpatient mental health facility, and fewer than five licensed therapists work in private practice. Glenn County Behavioral Health, the county's own department, runs offices in Willows and Orland (County of Glenn, n.d.), but capacity is thin relative to need.

Agricultural workers make up a significant share of Glenn County's PHP-enrolled population. This community faces unique mental health stressors — seasonal unemployment, immigration-related anxiety, housing instability, and the physical toll of fieldwork. Mental health stigma is also higher in agricultural communities, and many workers have never accessed any form of mental health support.

Chico · Oroville · Paradise · Gridley · Biggs

Butte County has a population of roughly 207,000 spread across 1,636 square miles (SimpleMapLab, n.d.), anchored by Chico, home to CSU Chico and Butte College, with Oroville serving as the county seat. The 2018 Camp Fire destroyed most of the town of Paradise, and federal disaster recovery funding continues to support the county's long-term recovery (Federal Emergency Management Agency, 2025); many residents have since resettled across the county, some still rebuilding years later.

PMHS provides telehealth therapy to PHP members throughout Butte County, including patients still navigating the long-term impact of wildfire displacement and loss. Rural communities like Gridley, Biggs, and Magalia often have far less access to local mental health providers than Chico itself, and telehealth closes that gap directly.

Colusa · Williams · Arbuckle

Colusa County is one of California's smallest and most agricultural counties, with a population of roughly 21,600 spread across 1,151 square miles of rice, almond, and walnut farmland (SimpleMapLab, n.d.). The city of Colusa serves as both county seat and largest town, with Williams as the only other incorporated city. The nearest larger cities, Sacramento and Chico, are each roughly an hour's drive away.

As with many small farming counties, licensed mental health providers are scarce locally, and many residents would otherwise drive to Yuba City, Chico, or Sacramento for care that isn't urgent enough to justify the trip. PMHS provides telehealth therapy to PHP members throughout Colusa County without that drive.

San Rafael · Novato · Sausalito · Mill Valley · Fairfax

Marin County, just across the Golden Gate Bridge from San Francisco, has approximately 291,000 residents across 520 square miles (SimpleMapLab, n.d.) and is one of the more affluent counties in the state, with San Rafael as its county seat and largest city. That affluence is not evenly distributed: West Marin, the county's largest region by land area, is largely rural and agricultural, with small coastal communities like Bolinas, Point Reyes Station, and Stinson Beach that are a world away from the county's wealthier eastern cities.

PHP-enrolled Medi-Cal members in Marin, particularly in West Marin, can face real gaps in accessible, low-cost mental health care despite the county's overall wealth. PMHS provides telehealth therapy to PHP members throughout Marin County, from Sausalito to the far side of Point Reyes.

Grass Valley · Nevada City · Truckee · Penn Valley

Nevada County spans an enormous range of terrain, from the Gold Rush-era foothill towns of Grass Valley and Nevada City up to Truckee, near the Nevada border and Lake Tahoe. With roughly 97,000 residents across 958 square miles (SimpleMapLab, n.d.), the county rises from rolling foothills in the west to towering Sierra peaks in the east, and winter mountain access can be a real barrier for residents in the higher elevations. Public transit between these towns is limited to a small county-run bus system.

PMHS provides telehealth therapy to PHP members throughout Nevada County, removing the need to travel mountain roads for a routine appointment, especially once snow closes in each winter.

Auburn · Roseville · Lincoln · Rocklin · Colfax

Placer County has approximately 423,000 residents spread across 1,407 square miles (SimpleMapLab, n.d.) and stretches from the Sacramento suburbs of Roseville and Rocklin, through the historic Gold Country town of Auburn, the county seat, up into the Sierra foothills and Lake Tahoe. It is one of the more populous PHP counties, but rural pockets in the eastern half of the county, well beyond the Sacramento commuter belt, still face real access gaps to local mental health care. The distance from Roseville to the Tahoe side of the county alone is over 60 miles.

PMHS provides telehealth therapy to PHP members throughout Placer County, from the valley floor to the mountains, on the same terms regardless of which end of the county you live in.

Quincy · Portola · Chester · Graeagle

Plumas County sits high in the northern Sierra Nevada, where the Sierra meets the Cascade range, with a population of roughly 18,000 spread across 2,553 square miles (SimpleMapLab, n.d.), one of the largest counties in the state by land area for so few residents. Quincy is the county seat, and Portola is the only incorporated city. The nearest larger city, Reno, is roughly 85 miles away, and Oroville is about 80. Winters here are long, and state highways 70 and 89 are the only real routes in or out.

PMHS provides telehealth therapy to PHP members throughout Plumas County, where mountain roads and winter weather make in-person care especially difficult to reach for much of the year.

Downieville · Loyalton · Sierraville

Sierra County is California's second-least populous county (Sierra County, California, n.d.), with roughly 3,150 residents spread across 953 square miles of rugged Sierra Nevada terrain (SimpleMapLab, n.d.). Downieville is the county seat, and Loyalton is the only incorporated city. The entire county has exactly one traffic light, and it was removed for a time after an accident before being reinstalled.

With this few residents spread across this much mountain terrain, local mental health providers are extremely limited. PMHS provides telehealth therapy to PHP members throughout Sierra County, regardless of how remote the address, on the same terms as anywhere else in California.

Santa Rosa · Petaluma · Rohnert Park · Sonoma · Sebastopol

Sonoma County, at the heart of California wine country, has approximately 459,000 residents across 1,576 square miles (SimpleMapLab, n.d.), with Santa Rosa as its county seat and largest city, and is one of the largest PHP member counties by population. The county stretches from the Pacific coast through vineyard country to the edge of the Mayacamas mountains. Wildfire seasons in recent years have added real, ongoing stress for many residents, including some who lost homes and are still rebuilding.

PMHS provides telehealth therapy to PHP members throughout Sonoma County, including support for wildfire-related stress and trauma, from Santa Rosa and Petaluma out to the more rural western parts of the county.

Yuba City · Live Oak

Sutter County is an agricultural county in the Sacramento Valley, with roughly 98,000 residents spread across 602 square miles (SimpleMapLab, n.d.) and Yuba City as both county seat and largest city. Sutter and neighboring Yuba County are closely linked as the 'Yuba-Sutter' region, sharing much of their local economy and services across the Feather River. More than 90 percent of Sutter County's land is used for farming, mostly rice, walnuts, and prunes.

PMHS provides telehealth therapy to PHP members throughout Sutter County, no drive to Yuba City or beyond required for a routine session. Live Oak and the more rural stretches south of Yuba City have even less local access to care.

Marysville · Linda · Olivehurst · Wheatland

Yuba County, paired with neighboring Sutter County across the Feather River, has roughly 86,000 residents spread across 632 square miles (SimpleMapLab, n.d.) and Marysville, a historic Gold Rush-era town, as its county seat. Much of the county outside Marysville is rural, with agriculture and timber as major parts of the local economy. Communities like Loma Rica, Brownsville, and Camptonville sit well outside the reach of most local health services.

PMHS provides telehealth therapy to PHP members throughout Yuba County, from Marysville out to the more rural surrounding communities like Wheatland and Olivehurst.
