Whole Hearts, Minds & Bodies
Whole Hearts, Minds & Bodies (WHMB) brings young people out of the clinic and into the outdoors through a clinically supervised, nature-based, therapeutic mentoring program for young people who have complex emotional and behavioral needs, and require intensive and frequent mental health support. WHMB is the only nature-based behavioral health treatment program certified by Medi-Cal, making us pioneers in the growing movement of nature as medicine.
Weekly one-on-one therapeutic outings are designed for high-need youth and young adults, and are led by associate therapists, social workers, and para-professionals trained in our 4Roots Method.









We’re transforming behavioral health by using the power of nature as medicine through our innovative, science-informed 4Roots method for holistic human development.
Our 4Roots Method
Helps young people who are navigating trauma, substance use, clinical depression, anxiety, and other severe mental health conditions treated with clinical interventions experience results that they weren’t able to get from past traditional behavioral health interventions and reduce or altogether eliminate psychiatric medication from their mental health clinical care.
Helps young people learn how to navigate the complexities of healing from adverse childhood experiences (ACEs) by building authentic relationships that provide a safe space for them to find purpose and strengthen their well-being through meaningful, intentional experiences in nature.
In nature, young people receive one-on-one support from trained therapeutic mentors who provide consistent, compassionate care and connection under clinical supervision.
Our Therapeutic Mentors
Help young people learn emotional coping tools, life skills, and empowered mindsets that instill a sense of purpose so they can navigate challenges in their schools, home lives, and communities with confidence.
Don’t ever shy away from challenges. They work with young people who have complex emotional and behavioral needs, and require intensive and frequent mental health support.
Have personally experienced transformation in nature and approach their work determined to ensure every young person can have these experiences, too.
Create an experience that feels authentic and accessible. Once a week, young people usually get picked up from home or school, complete an activity with their mentor in nature, share a meal together, and then return home a few hours later.
Work with their families and their other support networks so that they continue thriving after their participation in our program.
FAQ’s
-
Youth ages 6 to 24 with moderate to severe symptoms of distress. These needs range from complex trauma and substance use to clinical depression and anxiety. Previous participants have included wraparound-eligible youth, students receiving tier 3 support, and youth receiving specialty mental health services.
-
Whole Hearts allows young people to get intensive support while they stay in their communities. For young people and families who may be hesitant about traditional behavioral health programs, Whole Hearts offers an approach outside the traditional setting, one that has worked when other clinical interventions have not.
-
Youth and therapeutic mentors work together weekly, one-on-one. Youth are usually picked up from their home or school to participate in a nature-based activity with their mentor, share a meal, and return home three to four hours later. The program’s nature-based experiences occur in places ranging from parks close to the youth’s home or school to regional parks and wilderness areas.
-
Young people are matched with mentors who share similar backgrounds, interests, and lived experiences, which sets them up to build rapport and connection early. A mentor with therapeutic training most relevant to a young person’s needs gets paired with that young person.
-
Whole Hearts therapeutic mentors are trained in the 4Roots framework, Gateway’s science-based method to help young people learn, heal, and thrive. The framework is based on the science of healthy development, which shows that there are four roots for healthy, holistic human development: authentic relationships, nature connection, embodied peak experiences, and helping others. Mentors are associate-level therapists, counselors, and social workers; graduate-level-trained therapists working on practicums or internships; or highly skilled youth-serving professionals.
-
Young people’s time in the program depends on their needs, which is determined through assessments. The duration varies widely. Some young people need six months, and others need over three years.
-
There is no cost to participants who are Medi-Cal eligible. The program also provides any gear needed for outdoor activities.
-
Whole Hearts provides continuity of care for young people involved in multiple services and programs. Mentors meet with other service providers, as needed, to coordinate treatment plans and strategize how to deliver support without disrupting existing care.
-
The Gateway Mountain Center website has an online referral form that service providers can use to recommend youth and their families. Whole Hearts staff will contact families directly to set up an intake meeting.

-
Therapeutic mentors help young people balance the fears and rewards of taking risks and challenging themselves in nature. The program activities range in rigor. Activities may be more intensive, like rock climbing or hiking, or mentors and youth may simply take short walks, play, and explore nature in ways that help them foster belonging within themselves.
