Dr does not return phone calls, nor does he foloow up with patient after hospital stay. Office does not make any attempts to schedule post hospital stay appointments.

This doctor kept pushing me back and pushing me back until I told him that my health was more important than his busy schedule. My pacemaker placement had to be rescheduled 3 times! I was then discharged with 10/10 pain and Dr. Mark Colligan lied and said he is unable to prescribe pain medicine. If I knew I was be home right now, suffering, bruised, with 10/10 pain I would have never had this done with him. All he cares about is getting paid. He could care less about patient satisfaction or pain relief. Please do your research and find a cardiologist who actually cares. Office staff is rude and will laugh and talk crap behind your back. Don’t waste your time. There are way better cardiologists out there that actually care about patient satisfaction.

Moving and changing doctors always brings an element of concern and anxiety for me, however, I feel like I hit the lottery by getting into Dr. Colligan's health care management. The staff from the front door coming in to leaving the office was polite and professional.
