I have been coming to Dr Khan for approximately 3 years now. Dr Khan was recomended to me by Casa Grande Hospital after I fainted on a sidewalk and ended up in the hospital for diagnosis and brain scan. First I found I had a heart problem and needed a pacemaker and then thru the hospital I met Dr khan. He told me I had some brain enjury and Parkinsons. That was pretty hard to swallow but his kind eyes soft smile and strong hands kept me from panic and crying. To date my Parkinson’s has not progressed and I am no longer falling all of the time. If you practice what he preaches you are in good hands.
