About Key Transitions
Key Transitions is a non-profit teen treatment program, dedicated to helping teens find long-term recovery from addiction, behavior issues, depression, anxiety, trauma, and more. Key Transitions seeks to empower teens through building self-esteem, finding lasting connection, and exploring new passions. Treatment is geared for teens and young adults ages 13 to 30. Their Teen Outpatient, Teen Transitional Living, and Teen/Young Adult Mentoring Program provide individualized solutions to help those in need. Their intensive outpatient program includes family in the process by providing education and mentorship to help rebuild relationships. Individual counseling, group therapy, art and music therapy, surf therapy, and yoga are all a part of the program.
The transitional living program, Key Housing, is for male teenagers between the ages of 14 and 17. This home provides a structured living setting where teens boys can receive the mentorship needed to overcome mental health and addiction issues while still being able to focus on life skills and academics.
The Key mentoring program caters to men and women ages 13-35. Mentors are assigned to teens and adults based on their shared interests, personality style, and relevant experiences. Mentors meet with individuals at home and in the community, offering support for academics, resume building, and achieving their overall goals.
