  • Dr. Barnett, the Michelangelo of surgeons, has the magic touch. He’s replaced both my hips with perfect results; the first hip did ten years ago and the second last year, both with fantastic results. I now have excellent general health, zero pain, and great flexibility in a very active lifestyle of cycling, skiing, and hiking. Highly recommend.

  • I feel very fortunate to have Dr. Barnett as the physician that did my Hip Replacement Surgery. Surgery is never fun but I had a high degree of confidence throughout the process due to Dr. Barnett's experience and reviews from personal friends and acquaintances who preceded me who were patients of Dr. Barnett's.

  • He's as good as orthopedic surgery gets. I am a "typical" patient -- needed hip replacement, average patient in every way -- walking the day of surgery on. NO PAIN -- ever. Not the day of surgery, nor the day after, nor during my recovery. Very thorough, keeps you informed, checks your progress. With the surgery procedures he and Dr. Gorab perform, you heal quickly and well. Could not be happier with the surgery and Dr. Barnett.

  • I had bilateral knee replacement Sept. 2005 and they're still working fine in 2019. I continue to be very pleased to this day with Dr. Barnett
