Patrick Wiita, M.D.

Dr. Patrick Wiita grew up on the West Coast, mostly around Southern California. He went to college at the University of California - Los Angeles (UCLA), where he studied Microbiology, Immunology, and Molecular Genetics, before going to medical school at the University of Southern California. Dr. Wiita’s clinical expertise comes from thousands of hours of training at the Los Angeles County General Hospital (yes, that General Hospital). He was selected to remain at USC for six more years of post-graduate training in Adult Psychiatry, Child and Adolescent Psychiatry, and Forensic Psychiatry and many of his colleagues from training are now among his closest friends.

Like many other island transplants, Dr. Wiita vacationed on Hilton Head Island summer after summer with his family and in-laws (from Cincinnati, naturally) before seizing the opportunity to leave the big city and make HHI his home. When he’s not in the office, Dr. Wiita enjoys cycling, photography, taking his dogs to the beach, riding the Salty Dog sunset cruise, and putting off learning how to golf.
