Doctor Hansen is the best doctor I have ever known. He actually takes the time to listen to his patients and comes up with a treatment plan WITH you. He has great bedside manner, is very intelligent and professional. His entire staff is wonderful and they really treat you like a part of the Altitude Medicine family!

Doctor Sartor is a great doctor who is very respectful, very thorough, and very helpful. She will go above and beyond in testing your problems, if one exists, and is mindful of insecurities and keeping you well.

I have had too many doctors who have to consult to their notes to recall who you are, every visit. Dr Hoffman has been supportive in so many ways. If you want a very caring Doc with excellent bedside manners Dr Hoffman is my only suggestion!

Dr. Pariset is the best doctor I have ever seen. She is very caring, a great listener, makes you feel at ease, and you feel her undivided attention to you and your needs the minute she walks into the room. So thankful to have Dr. Pariset as my primary healthcare provider!
