I have been with Next Generation since it was started, roughly 15 years. Before, when Dr. Mortimer was with Dr. Ashbaugh, he had diagnosed him with a heart murmur. Since he knew my sons history, I felt it very important to stay with him, therefore I switched practices. I have never had trouble getting in when needed and never had any problems with the staff, no matter who it is. I now have 3 children with him and have always had excellent service and care.
