History & Philosophy

Commonwealth Psychology Associates® (CPA) was formed in 2004 to provide a comprehensive range of behavioral health services within one group practice.

While working privately as a neuropsychologist for many years, our founder, Dr. Andrea Piatt frequently struggled to find appropriate treatment and follow-up resources for her clients. Even when options were identified, lengthy waiting lists and insurance restrictions often limited timely access to care. To address these problems, Dr. Piatt endeavored to create a full-service, multi-disciplinary practice where clients can obtain all of their needed services. Since then, Commonwealth Psychology Associates® has grown to include approximately over 65 psychologists and psychopharmacologists in six convenient locations.

Each clinician has been selected for the unique, specialty knowledge and experience they bring to client care. Our staff of doctoral-level psychologists and psychopharmacologists offers a wide range of expertise, extensive clinical experience, and knowledge of state of the art, evidence-based therapeutic and assessment approaches. Most staff members have completed formal post-doctoral fellowships in their respective specialty area and many have held or hold academic affiliations with highly regarded academic institutions including Brown University, Harvard University, Dartmouth University, and Boston University.

We strive to provide the highest quality clinical services and outstanding customer service, all in a warm and attentive environment. We welcome you to contact us if you’d like to learn more about us and the services we offer.
