Louis Propp , PsyD, is a clinical psychologist who has been in private practice for nearly forty years. He conducts weekly online supervision for home-based workers and maintains a small teletherapy practice in Maine. He has also consulted for almost 35 years for a family resource center in Vermont. He has previously taught different graduate-level psychology courses in child psychology at Antioch University New England. He is a member of the Maine, Vermont, and American Psychological Associations, as well as the Association of State and Provincial Psychology Boards. His first position was in upstate New York, doing play therapy in a school for emotionally disturbed children. In 1984, he became director of a satellite community mental health clinic in Vermont. After three years, he left the clinic and joined a small private practice group.

In the 1990s, he helped transition the group into a large, multi-specialty practice to deal with the restrictions of managed care. In 2010, with his wife, Kristin, he formed a private practice focused on children, adolescents, and families. They relocated the practice to the state of Maine in 2020 during the COVID-19 pandemic. Dr. Propp continues to see patients remotely in Vermont and Maine.
