Dr. Kellar is a multitalented doc. He always explains what's going on and gets down to business. And he's an Army Veteran (big plus to me).

Dr. Kellar and his staff were very attentive and had a professional yet caring bedside manner. The updated equipment in the new office is efficient and mobile making it easy to take care of patients in their exam rooms.

Amanda is wonderful. She listens carefully and decides on a treatment she feels will help. She then follows up to see if it would benefit me more to customize my medications. She is warm and compassionate and I would like to thank her and the staff for such great care!
