February 28, 2025PARKWAY HEALTH CENTERDr Masteller is amazing. He very obviously cares for his patients. He is very responsive to questions during but also after any visit. In 50 years seeing primary care physicians I would rank him at the very top of the list. The entire staff is amazing and I have no reservations in highly recommending Dr. Masteller to anyone looking for a primary care physician.
