General Psychological Services

We provide high quality psychological services to children, adolescents, adults, relationships and families. We strive to provide optimal quality treatment in a comfortable environment. We coordinate with appropriate medical professionals as needed. Office management staff assist in the ease of insurance billing and reimbursement. Treatment can occur through individual psychotherapy or couple and family psychotherapy.  Our therapists use empirically validated approaches to ensure high quality psychotherapy.  Yet, therapy is individualized for each person and the specific needs that are presented. We also provide a variety of educational and medical psychological evaluations and consultations.  Psychological assessment offer objective measurements of individuals.  These are tools that can provide a great resource for the schools system when there is a question of learning or behavioral problems.  More medical procedures are requiring psychological evaluations to determine whether the patient is psychologically appropriate for the medical intervention.  Our reports back to the referring agency our clear and focused on the questions at hand.
