Accepting new patients & second opinions
Full spectrum of adult spine — common to complex.
Select a region of the spine to see what Dr. Mushlin treats there and how. Most problems never need surgery; when they do, it is done with modern, minimally invasive techniques whenever possible.
“Being a strong surgeon is more than being surgically skilled. It's about a balanced plan, aligned with the patient's goals. I listen closely.”
Dr. Mushlin is a board-certified neurosurgeon who has dedicated his career to the spine. He completed neurosurgical residency at the University of Maryland, where he also completed an enfolded complex spine fellowship. Drawn to the most demanding spinal cases, he then pursued additional fellowship training in complex spine and neurotrauma at the University of Pittsburgh.
Today he serves as Director of Spine Surgery and as an Associate Professor of Neurosurgery, where he also helps lead the training of the next generation of neurosurgeons.
“Dr. Mushlin gave me my life back at 69 years old. I was unable to stand or walk, but after a surgery that basically rebuilt my spine, I am walking over a mile and doing all the things I couldn’t for years. I am grateful and would recommend Dr. Mushlin and his staff to anybody.”
I am very pleased with the results of my surgery — I no longer have pain in my upper legs and I can walk better. Dr. Mushlin was very professional, and I am very grateful that my operation turned out so successful.
I was up and walking after spine surgery in two days — no real pain, only discomfort at the surgical site. Arguably the best back surgeon in the country.
Dr. Mushlin was very attentive and caring. He listened, answered all my questions, and addressed my concerns — impeccable bedside manner. I feel very comfortable and confident heading into back surgery under his care.
