Dr. Wigger is an excellent caring, and kind clinician. No matter your questions or concerns, he can explain it to you and what to expect. I worked as a Nurse Clinician for 40 years. Dr. Wigger is at the top of my list for a number one physician.

Dr. Wigger is proficient and efficient. He was one of my transplant doctors. I trust him explicitly. I am blessed to have him as my physician now at the Knoxville clinic. He may not retire until I no longer need him!!! LOL
