Chosen for their knowledge, experience and dedication.

Dr. Pienkowski, M.D., P.h.D.

Founded his medical practice in East Tennessee in 1984. In the prior decade, Dr. Pienkowski honed his research and clinical interests in distinguished institutions such as The Wistar Institute at the University of Pennsylvania, Henry Ford Hospital, and the Johns Hopkins University School of Medicine. When Dr. Pienkowski became ready to set out on his own, he was motivated to practice medicine where people needed him and his colleagues the most.
