Thank you, Dave!
Dr. Gnaim is the best hands down. He has gone the extra mile for me when I had a health scare, just to make sure I was OK. I have sent my friends, and family to him as I know they will get good care. The support staff are on the ball, and I never have to wait long. We have a lot of Drs. located closer to us, but I drive the distance; he is worth it!

Thank you, Barb!
Dr. Charlie Gnaim is my favorite cardiologist of all time (and I've been to many!) First of all he really knows his stuff and I highly trust him as my heart doctor! Secondly, rarely do you find a professional medical M.D. that is very down to earth and truly cares about a patient as he does!! I consider him a friend as much as an excellent cardiologist! Thank you Doc for your great patient care.
