Dr. Kassinove began his career working as a case manager in a large mental health clinic. He realized the difficulty clients had in receiving quality care. Often clients could not leave their home due to distance or weather and, therefore, did not receive the care needed.
To further his understanding of cognitive and behavioral change, he obtained his Ph.D. from Hofstra University in Clinical and School Psychology. He then served as a professor for five years teaching others about clinical practice and conducting research on addictive behaviors, anger and behavior therapy. He left academia in 2003 to focus on more global changes, which led him to co-found Theramatch, Inc. His passion is to create a system of care in which clients can find and access information about mental health professionals.
