Found Dr Gass to be very detailed, listened and heard concerns, patient and helpful. Explained test fully. Did not feel rushed. Nurses and staff very professional. Thankful to have found him five years ago. Gass team would be hard to beat!

I have been Dr. Gass' patient for several years. IMy review is based on all the times I have been seen by him. After I relocated I was referred to him by my primary care physician because of respiratory issues for which I had been treated for about five years before seeing Dr. Gass. I had already been diagnosed with bronchiectasis and was on oxygen 24/7. Dr. Gass ordered the appropriate testing and discussed a treatment plan with me. Since then, I have seen him regularly. He has prescribed various medication which provided significant relief to me. Bottom line, I now only need oxygen occasionally. I am able to function normally without it except when I exert myself more than usual. I give Dr. Gass and his staff full credit for helping me to live a life without having to carry oxygen with me everywhere I go. I highly recommend Dr. Gass for any person who has respiratory problems. He is the best. '
