I was surprised how easy it was to get an appointment within a short amount of time. I didn't have to wait long in the office to see Dr Kellar like I do at other specialists. He answered all my questions but still made my appointment quick and concise. I also had experience with his respiratory therapist Melissa, she was great as well. All around a great couple of visits!!

The Doctor is ok but the staff is poorly trained in customer service and have even taken parts of a device that of course I was billed for. and getting to talk with their billing Department is a joke 10 calls and always get their voicemail promising to call back and never do.
