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.

“As Michael’s wife, I have watched him deal with this hip pain for most of our 33 years of marriage. I’ve seen how much it affected the way he walked, what he could do, and just his everyday life. More than anything, I wanted him to finally have a real chance to get out of pain. Traveling from California to Maryland for surgery was a big decision. Michael has been an attorney in San Diego for decades and knows many of the top surgeons here, so going across the country was not something we took lightly. The doctors we saw here were talking about a much bigger open surgery. My husband, being my husband, had an enormous list of questions. A lot of the answers were already available in the information Dr. Christoforetti had put together, and his physician’s assistant, Brian, answered many of the others. When we met with Dr. Christoforetti, he carefully went through everything with us and never made us feel rushed, even with Michael’s never-ending list. One of the things that made me feel much better was understanding that doing the surgery through small openings did not mean he could see less. With the camera, he could actually get a very detailed view of what was going on and repair what he found without putting Michael through the much larger open surgery that had been discussed. Over the years, Michael tried just about every type of treatment available — injections, physical therapy, and other non-surgical treatments — without lasting relief. It meant so much to me that Dr. Christoforetti was finally trying to fix the actual problem instead of just treating the pain again. As a wife, there is a different kind of trust involved. Michael had to trust the surgeon operating on him. I had to trust the person I was handing my husband over to. Dr. Christoforetti made that easy. I felt that he truly cared about Michael and treated him the way you would want someone to treat a member of your own family. His whole team was wonderful to us. Being so far from home made both of us nervous, and having a direct number to Brian, his physician’s assistant, gave us a lot of comfort. Dr. Christoforetti, if you ever make it to California, there will always be a place for you at our table. You took such wonderful care of my husband, and I would love the chance to return the kindness by making you the best home-cooked Persian meal of your life.”

“Dr. McCormick was very patient with my 4 year old who had a foot injury! The front desk was very efficient checking us in. Shelby, the Xray tech, was sweet with my daughter talking her through the X-rays process. Dr. McCormick was able to get some smiles out of her too. He’s great with children and did a thorough job explaining her injury. MOS continues to deliver exceptional healthcare!!”
“Dr. Fitzgibbons is a surgeon who does not push for surgery first thing without giving less invasive alternatives a try. He gave me a cortisone injection and told me to wait and see if that helped my hand. I like his cautious approach.”
“Dr Raffo had a wonderful team for my shoulder rotator cuff surgery. They are very experienced, knowledgeable, friendly, and professional. Five days have passed after my surgery and I no longer have any pain from the surgery and recovering well. Many thanks to Dr Raffo and his entire team!”
“Dr. Fitzgibbons was friendly and very detailed in his explanations of my concerns. He spent much time explaining the situation and treatment options.”
