Dr. Keller is no doubt one of the best doctors that I have had the privilege of being cared for by he is not only brilliant but he’s caring and you’re not a number to him. He just is very professional and his manner is very good I guess we could call it chair side however being a sleep apnea Dr. as well I guess we can call it bedside manner. In any rate I am so thankful that I have a doctor who cares and that is willing to work with me to encourage me to get better. Mainly to wear that mask thank you Dr. Kellar
