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. '
