5 /5 JoAnn Rumelhart: Dr. Mark Olbina is an outstanding dentist. He is a true professional and extremely good at complex dental procedures. Every member of the staff at Amelia Gentle Dentistry truly cares about the patients and they do everything they can to make the experience a pleasant one. I highly recommend Dr. Olbina and Amelia Gentle Dentistry. This is no ordinary dental office. They go above and beyond for the well being of their patients.
