Dr Buck is great ! Listens very well and heck of a drummer ! I would recommend they look at office staff issues as it is very difficult to get a phone call back with questions from a nurse ! Sometimes heart issue questions should not have to wait 24 hours plus to get a phone call back if u are lucky
