"Dr. John Harris is an amazing doctor, he is kind, patient and takes time to listen to what the patient is actually saying which is really rare these days. He is especially good for immigration and FAA purposes. He helped me and my family with all our issues. We have been going to him for years now."


(Patient's review on

"I went there for USCIS medical exam. Awesome staff,very attentive,very good environment, doctor is very professional.Even the staff told us we can get vaccines anywhere, we got ours on local health county saved alot of money. If anybody looking for USCIS physical exam,best place in Colorado."


"I am an FAA commercial pilot that was grounded for a medical condition that prevented a renewal of my my medical certificate. Dr. John Harris provided guidance “above & beyond” by contacting the FAA directly & I was able to receive my new medical certificate & continue flying. My sincere appreciation to Dr. Harris & his staff. I recommend this organization highly for FAA medical concerns."
