  • Dr. Vadasdi: It’s been over a year now since my elbow surgery and I’m back in full swing. Literally! My golf swing- I had my best season to date (over 45 rounds) and achieved my lowest handicap score of 10.8. I can’t thank you enough for applying your surgical skills in repairing my elbow. With PT my recovery was smooth and quick. I was back up and running in just a few months. I feel better and stronger than ever. Your staff from start to finish was professional and compassionate. Thank you. – DT (Elbow)
