Outstanding! Dr. Sager was able to get me into back into sinus rhythm for multiple years when the previous cardiologist's work only lasted six months.

Never saw him on 5/13 he never came in the office to speak with me. Which I did not like. Even if you have a intern the doctor that you are scheduled for should always come and introduce thereself or step in to speak with you at some point during your visit.
