Dr. Ash has received specialized training working with children, adolescents, adults, and families who present with various concerns, including but not limited to: depression, anxiety, oppositional and disruptive behaviors, acculturative stress, identity development, and trauma-related symptoms. As a bilingual psychologist, she has domestic and international experience conducting individual and family therapy in both English and Spanish.

Additionally, Dr. Ash’s forensic training working with families in the midst of high conflict divorce enables her to work effectively with adolescents whose families are court-involved, as well as with caregivers seeking parental guidance during court-involvment or around family change issues. Dr. Ash has also completed training in providing and interpreting neuropsychological assessments of children and adults, which enables her to assist clients to identify assessment needs. This is particularly helpful for families determining whether or not assessment may be helpful for providing diagnostic clarification, treatment planning, or understanding testing clients may have already received.

Client Resources

Beginning therapy and finding the right therapist can be challenging. Following the first few sessions with a new therapist, you should experience a sense of feeling heard and understood. Given that, I consider the first several meetings with new clients an opportunity to get to know one another and collaboratively determine the most appropriate course of treatment. If for any reason it becomes clear that I am not the best clinician to meet your needs, I will do my best to assist you in finding a therapist who is a better fit.

Prior to your first appointment, I will provide you with additional written information and forms describing my practice in greater detail. Please note that at this time I am not an in network clinician for any insurance company, though I am happy to provide documentation for insurance reimbursement upon request.

My office is located at 22 Hilliard Street, Cambridge Massachusetts 02138. There is limited metered parking in the area and the office is a 5 to 10 minute walk from the Harvard Square Red Line.
