What Our Patients Are Saying

Dec 2, 2021

I appreciate the terrific care and service provided by Dr. Vaughan and team. Dr. Vaughan's diagnostic process is brilliant, you see what he is seeing in real-time, an involvement that is educational and calming Dr. Vaughan is straightforward and engaging, besides being funny and a good guy. Felt like I was in expert hands. And his staff Jackie and Kathleen are terrific, going above and beyond to ensure medicine access that Medicare found complicated. Hope not to need surgery, but if I do, I am grateful to be in Dr. Vaughan's care.

Dr. Vaughan is literally a lifesaver. I’ve been a patient for 19 years. I went from having to see him monthly when I was at my worst to semi annually for the last 17 years. He is compassionate, knowledgeable and committed to his patients. I’ve referred several people over the years and they’ve all been extremely satisfied with Dr. Vaughan. He and his staff are the best...you are in great hands!!!
