Meet The Doctor

What can a patient expect when they have you as a doctor?

We try to provide comprehensive and compassionate care for our patients.

What is the most important factor in a doctor-patient relationship and why?

The most important factors are relationships and a team approach where the patient is involved in their care.

What hobbies or activities do you enjoy when you're not working?

I enjoy outdoor sports, listening to Memphis music and church activities.

What about your line of work do you find the most rewarding and why?

Practicing medicine is rewarding in that you have the ability to help meet the needs of people that are sick and hurting. That is part of ministry of Christ, to help the sick and provide comfort. Also through comprehensive physicals we can help detect diseases early to prevent complications of diseases.
