Mary provides each client with a thoughtful, comprehensive, and holistic assessment in a supportive and therapeutic environment. She strongly believes in empowering clients with information about the underlying neurobiology and risk factors that can lead to various mental health symptoms. Mary says, "I enjoy providing education in the area of psychopharmacology in order to best collaborate with each client in regard to their individual treatment plans. I find that successful recovery requires connection and trust and I make every effort to make sure that each client feels supported and heard. I am a very strong advocate for non-pharmacologic interventions that can maximize recovery and minimize use of medications. I stay up to date on the latest research in the field of psychology in order to make the most informed recommendations."
