Conditions & Treatments Include:
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)
My experience was fantastic! Dr. Vadasdi was incredible. She did a great job on my shoulder. I strongly recommend that anyone who is facing shoulder surgery to use Dr. Vadasdi.
I have had shoulder surgery before and Dr. Vadasdi is the best and so is the ONS staff! (Patient Review)
I find Dr. Vadasdi to be a genius and compassionate doctor. Her care of me as her patient was outstanding! (Patient Survey)
I have been coming here for at least 15 years and have seen a variety of amazing doctors … Dr. Greene being a favorite in our household for years and would trust him with everything. Recently I broke my elbow and was sent to Dr. Vadasdi. She was amazing! Great with surgery and aftercare. Very compassionate throughout the whole process! Thank you ONS for getting me through everything! (ED)
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)
Dear Dr. Vadasdi – I neglected to tell you today how much I appreciated the excellent rebuild of my shoulder. You are obviously very talented as my recovery demonstrates. I recommend you to everyone! Thanks again for your time, concern, and operating skills. Have a great New Year! (CS)
Dr. Vadasdi– I was given great information prior to and post surgery. The staff and Dr. Vadasdi were very responsive. I was very pleased with all aspects of the experience. (Anonymous)
