Fellowship-trained specialists | Bethesda. Rockville. Germantown.
Orthopedic Care That’s Personal, Unhurried, and Expert
Same-day appointments with fellowship-trained specialists in Bethesda and Germantown, MD.
Our philosophy
Expertise. Trust. Access.
Three pillars that define how we practice — and why patients in Montgomery County have trusted us with their orthopedic care for over three decades.
Pillar One
Expertise
Our physicians trained at the most prestigious orthopedic fellowship programs in the country — and have served as team physicians for professional sports franchises at the highest levels of competition. That expertise is what you get at every appointment.
Pillar Two
Trust
Patients in Montgomery County have returned to us — and referred their families — for over 30 years. That loyalty is earned one appointment at a time: clear communication, honest options, and a care team that treats you like a person, not a chart number.
Pillar Three
Access
Getting to the right specialist shouldn't be a battle. We offer same-day and next-day appointments, 24/7 online scheduling, three convenient locations, and physicians who actually return your calls — plus in-network coverage with most major insurance plans.

“After more than 20 years of hip pain, especially on the right side, the pain finally became bad enough that surgery had to be seriously considered. Over the years, extensive long-term physical therapy and multiple cortisone and PRP injections were tried without lasting success. At one point, an expensive placental-tissue injection was proposed. It sounded appealing, but after looking carefully at the research, I could not find convincing evidence that it would repair a significant structural tendon tear. I am an attorney and spent part of my career representing physicians, hospitals and pharmaceutical companies. That certainly does not make me a doctor, but it does make me careful about medical claims and major medical decisions. Several excellent orthopedic surgeons were consulted. One was Dr. Michael Muldoon in San Diego, a superb and highly experienced hip endooscopic surgeon. He is a graduate of the U.S. Naval Academy in Annapolis, trained at the Mayo Clinic and previously directed the Hip and Knee Service at Naval Medical Center San Diego. What impressed me tremendously was his honesty. Dr. Muldoon explained that, although he had extensive hip endoscopic experience, he had not done enough of this particular gluteus medius repair endoscopically to recommend doing mine that way. He could perform an open repair, but highly recommended Dr. John Christoforetti for the endoscopic approach. That distinction mattered a great deal to me. An open repair generally means a larger incision and more disruption of the tissue around the hip. An endoscopic repair uses small portals and specialized instruments, with much less soft-tissue disruption and potentially fewer wound-related complications. For this type of surgery, I wanted someone who had performed a great many of these repairs through the less-invasive approach. After extensive research, I could not find anyone who remotely matched Dr. John Christoforetti’s combination of experience, qualifications and focus on this type of surgery. Dr. John Christoforetti is a board-certified orthopedic surgeon, graduated from Georgetown University School of Medicine, has performed thousands of endoscopic procedures and served as President of ISHA—The Hip Preservation Society. He also teaches advanced hip arthroscopy techniques, including knotless labral repair. There is an old saying: if all you have is a hammer, everything looks like a nail. Medicine is no different. Even excellent surgeons naturally tend toward procedures they know best. Patients should take their time, get several opinions and ask how many of their exact procedure a surgeon has actually performed. Once surgery is done, there is no rewind button. That is why I flew from San Diego to Maryland specifically to have Dr. John Christoforetti perform my surgery. My operation included an endoscopic gluteus medius tendon repair, removal of the inflamed trochanteric bursa and arthroscopic treatment of the damaged portion of the labrum. The surgery was performed at Watkins Mill Surgery Center, a new physician-owned orthopedic center with specialized equipment for procedures such as hip arthroscopy. The facility was impressive, but the personal care was even more impressive. Brian Long, PA-C, gave me his direct phone number and was available by call or text. Knowing I could reach someone who actually knew my case was incredibly reassuring. The entire experience felt truly one-on-one rather than like being passed through a large medical system. It is far too early to judge the final surgical result. Recovery from this repair is lengthy, and my walking and activities are currently very restricted while the tendon heals. So far, however, I have not needed pain medication since surgery. The experience with Dr. John Christoforetti, Brian Long, PA-C, and their team has been the best doctor-patient experience of my life. Traveling across the country for this surgery was absolutely worth it!”

“I researched several different surgeons before selecting Dr Raffo. He has a great educational background, a high level of experience, and great reviews from patients. My experience was a consultation for my knee. My MRI report said torn meniscus. Dr Raffo confirmed the report, and explained a very clear path to recovery. He explained I did not need surgery in a very easy to understand manner. If you are looking for an excellent surgeon, look no further.”
“Visit was great. Appt was on-time. Dr was helpful and suggested solutions that helped with my knee pain.”
“Dr Fitzgibbons was great - very nice, very down-to-earth & very quick to address & treat my issue. I highly recommend him.”
“The best!”
“An outstanding service.”
“Dr. Feldman listened to my concern about my ankle that has been going on for over a year. He was awesome and I really appreciate his compassion and kindness!”
