5 /5 Dr. Ronald K. Powell: I worked with some of the Best Dentist and Oral Surgeon in the Military during the Seventies. Over the years I looked for a dentist that was comparable. Many failed the test, but Dr. Sheila Shah excels above some of the best in the world. Her practice is a practice of excellence from the front desk to final moments. She is at the very top of the Dental field.
