      Dr. O'Neill performed my ablation surgery, but he punctured my femoral artery, which created complications requiring follow-up surgery. I understand that this can happen, but Dr. O'Neill didn't follow-up with me for almost 2 days as I laid in the hospital bleeding internally. When he did show up, he was there for about 2 minutes, and that was the last I ever saw of Dr. O'Neill. The administrative nightmare followed between Dr. O'Neill's staff and the insurance company, which lasted a year.

      Why Does Experience Matter?

      Even specialists specialize. One orthopedic surgeon might do nothing but hip surgeries, while another does nothing but knees. If you want the best possible care, it’s critical to match your medical need with the doctor who truly specializes in treating it.
