Extremely compassionate, professional, and educated provider. I was especially impressed that Dr. Mullin took the time to read my medical records prior to the appointment to understand my medical history before our first meeting. Dr. Mullin did not rush the appointment and was willing to take time to provide suggestions to improve my health. I would highly recommend Dr. Mullin to friends and family. Highly impressive provider.

I came in as a new patient. Dr Mullin spoke with and explained possible procedures and outcomes. He has wonderful bed-side manne; therefore he listens and speakers with his patients; not to. Presently he has ordered 3 tests to be completed. However only one has been completed today. The other two very shortly so there could be no test results to be given at this time.
