If your main treatment need is for family therapy, I believe it would be better for you to work with a Licensed Marriage and Family Therapist (LMFT), who is more solely focused upon that modality of care.
However, I do offer child-parent relationship play therapy, family play therapy, attachment-based EMDR, and am a licensed educator in Positive Discipline. With my child and teen clients, I work closely with parents and other family members as needed to support progress.
This involvement may include meeting with parents and other family members in session with the client, or separately.
