APP was established in the late 1960's by Dr. Desmond Gravitt, a medical psychiatric specialist originally from South Africa. In 1997, in preparation for his retirement, Dr. Gravitt began turning operations over to the now current owner, Dr. Bonita Patton, who is a licensed psychologist and marriage and family therapist. Over the years APP has grown from one location in Rochester, MN to now include satellite offices in Faribault, and Owatonna.

In 1998 the Faribault office was designated a rural health needs office through the National Health Service Corps; this allowed those in the Faribault community to receive equal access to high quality care.

In 2015, the Rochester office moved into a new state-of-the-art building and added sleep labs, phlebotomy lab, acupuncture, and pain management. The expanded Rochester location allows us to serve a greater number of people. APP has a large diversified team of professionals with extensive training and expertise; our focus is to treat the individual as a whole. We serve clients in all stages of life from young children to seniors and we offer a broad range of services.

APP has proven itself as one of the most well-respected psychiatric and psychology practices in Southeastern Minnesota.
