His office was closed ,and he moved,never notified his patients. Upon needing a script refilled,I tracked down a Ph # in Columbus, Ohio. The person answering the phone was rude and advised me to have my family phys. to refill the med. Other problems with this office in the past include, filthy offices, very rude staff, the Dr. is never on time, the last 2 visits I waited and was finally seen by his assistant. I had a long talk with Dr. Gaddam after doing a procedure on my wife. He was 4 hr late for that procedure and the hospital staff stated that it was par for the course. He seems to be a nice man but has NO CLUE on how to run a successful and efficient medical practice. Both my wife and I now have a different cardioligist.
