Dr. Vadasdi was wonderful. She performed two surgeries, the first to find out what was wrong with a repair conducted by another surgeon, and a second to then fix the problem. She also thought to collect tissue samples during her first surgery, then finding that I had an infection that required 6 weeks of daily antibiotic infusion. I am now 100% healthy and back to normal routines, including yoga (at age 68!) (comment from RateMD)
