About Marimba.


Marimba is a Marin County, California psychology practice exclusively for children, adolescents and their families.

We specialize in child & teen individual therapy & psychological testing, family therapy, and parenting support & skill development.

The goal of all services at Marimba is to make significant gains in the overall quality of a child's life, including the development of a positive sense of self and successful relationships with peers and family.

In over fifteen years of specializing in therapy and testing services for children and adolescents, we've found the greatest success comes from a fully collaborative approach between the therapist, client, parents, and other key adults in a child's life including their teachers, tutors and psychiatrist.
