Dr Kelsch was recommended by 2 people I know. I kept getting colds and my sinus always were pounding. Dr Kelsch did a cat scan and saw my sinus passages were very narrow. He suggested a balloon sinuplasty over surgery. Had it done in office without any problems. Dr Kelsch himself called me the next day, Saturday to see how I was. On Tuesday I was still feeling pressure and wanted to make sure everything was ok. I called the office and they got me in that afternoon instead of having to wait to Thursday for my follow up. Everything looked good and the pressure is part of the healing process. If you decide to have this procedure give yourself a few days after to recope. Some are ok the next day. I needed about 5 days to feel better, but I am a slower healer.
