Recent Patient Testimonials


The doctor and staff were fantastic – they explained everything they did in detail and they were so accommodating.
– Kris R


Dr. Swerdlin made the experience great. He took the time to explain everything. I never waited more than 5 minutes in the waiting room and less than that when I got in the exam room. In all I had 3 procedures done at one time. I had septoplasty, sinus balloons, and removal of the uvula. Now I can breathe out of my nose, I sleep all night long, and I no longer snore.
– Kevin C
