Patient Reviews

Patient

★★★★★

Dr. Warner is an outstanding Cardiologist. His diagnosis and evaluation skills are amazing. He saved my life by spotting something just off a bit on my stress test. Scheduled angioplasty and I ended up getting 3 stints.

Patient

This guy is in charge of OSU wexner medical center. He needs to look into how his emergency department is failing its patients. It has a rating of 1.9 . My mother has waited for 13 hrs in the emergency department. The staff are rude and unprofessional.
