On a Personal Note:

“I love my wife, Janie, and my children Becky and her husband Pat, Amy and Zachary more than anything else in the world. Janie and I were married in 1980 and we have three wonderful kids who have taught us many important lessons about raising children with love and grace and an open hand.

My faith in God is the source of the love and compassion I offer my patients as a physician. As I treat each patient, the spiritual life of each individual is considered an integral part of his or her physical and emotional well being.

I enjoy music and playing my Martin guitar and singing oldies or Christian worship music with my friends and family. I love taking walks and gardening with my wife Janie and we go skiing each winter as often as we can. We also like traveling and discovering new places around the world.

I have been an elder at Greenwood Community Church since 2000 and have seen how important faith is to the lives of children and their parents. In the past, Janie and I have taught Sunday school classes for two and three year olds. Now we are involved in the Stephen’s ministry at church to come alongside people in their time of need.”
