    He did sinus surgery on me in November, 2018. Since then, I have also been under his care during a period of recovery. The surgery was without complications or surprises, done just as he described and in the time he had outlined. The recovery went well, with fits-and-starts that he warned me about in advance. Last seek was my final appointment and he was professional, friendly and understanding each time we met.

He spent a lot of time listening to me describe my symptoms and how it affects me daily. We discussed treatment options and he explained why he would choose one option over another, he discussed probable outcomes, side effects and what would change when i'm off blood thinners. He took his time, seemed truly interested and seemed to enjoy his job. We felt he had my best interests in mind.
