Better known as our Penngrove Program, Muir Wood’s residential primary mental health program for girls serves clients who have mental health concerns like anxiety, depression, or trauma. Our treatment approach focuses solely on mental health issues and stands separate and apart from our girls dual-diagnosis programs that address the co-occurrence of mental health and substance use disorders. Learn more about how we can help your family heal.
Muir Wood understands the unique challenges faced by teen girls in today’s world and the trauma that can be a byproduct of social media, bullying, relationships, peer pressure, physical and emotional abuse, and more. Our residential primary mental health programs for youth are dedicated to the treatment of adolescent girls mental health disorders. We specialize in the treatment of generalized and social anxiety, panic attacks, depression, self-injury, mood and personality disorders, and trauma.
Our program is accredited by the Joint Commission, considered by many professionals to be the gold standard in healthcare program accreditation. We are also certified by the California Department of Health Care Services, licensed by the California Department of Social Services, and verified by Psychology Today as a trusted teen treatment provider. The program is staffed by a highly credentialed team of therapists, supported by full-time psychiatrists and nurses.
We believe that teen girls have the capacity to grow and support one other if given the right tools. “It is so powerful to see the capacity that human beings have for change, for healing, and to empower and support one other,” shares our therapist in the video below. Explore our other videos.

In comparison to another residential facility, we found Muir Wood to be focused on helping the child vs. just running a business. The Dr.’s and therapists were great, our child made progress after a long time of spiraling downward, and expenses and the entire process was transparent.

Muir Wood has been a blessing for our family. The entire staff was unbelievably supportive, not only to our son in his time of crisis, but to our entire family.

“When you call Muir Wood, you will either reach me or one of my staff. Please know that we are 110% committed to helping you find the best treatment for your teen and will hold your hand through the entire process. And if we aren’t an ideal fit for your child, we’ll help you find a program that is.”
The varied treatment modalities that Muir Wood uses to address mental illness in teens are all evidence-based. All of our young clients are treated with proven approaches including:
Cognitive Behavioral Therapy (CBT), which challenges unconstructive thinking and behavioral patterns
Dialectical Behavioral Therapy (DBT), which aids in the management of strong emotions
Seeking Safety Therapy, which helps teens with trauma and PTSD heal
Acceptance and Commitment Therapy (ACT), which teaches teens to accept their emotions and live more mindfully
In addition, we offer modalities such as art therapy, music therapy, breath work, health and physical education, and trauma-informed movement groups. When used in concert with evidence-based therapies, experiential therapies give teens a comprehensive toolset for healing.
We understand that no two individuals or families are the same, and every teen needs individualized support to thrive. We provide person-centered care that focuses on meeting our young clients where they are. Treatment planning reflects the collaborative efforts of the client and their treatment team. The treatment plan takes into consideration the individual teen’s strengths, needs, abilities, preferences, and goals for treatment.
Our residential primary mental health program for girls features an on-campus Muir Wood Learning Center, which is recognized by the Western Association of Schools and Colleges (WASC) as a supplemental learning program. Teens attend the program 15 hours per week and are supported by credentialed single- and multiple-subject teachers. The program enables teens to maintain continuity with their home schools, ensuring a smooth transition back to the classroom following treatment.
Muir Wood provides the opportunity for growth and development in a peaceful, serene environment. We believe our idyllic campuses and communities add to the healing experience and work in concert with the professional services we offer. Our home-like settings are supervised around the clock and provide ample amenities and expansive outdoor space to aid in the healing process.
Muir Wood is committed to meeting the need for high-quality, in-network mental health care for adolescents and their families. To get started on your healing journey, fill out an assessment form or contact our team.
