What Our Patients Are Saying

I was a patient of Dr. Fong‘s a few years ago. I was plagued by recurrent sinus infections and fatigue. She recommended sinus rinses. This has worked wonders and I think I’ve only had one sinus infection in the interim and feel much better. That was a great help!

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.
