About me

Dr. Alekos Theologis is an orthopedic surgeon who specializes in caring for adults and children with a wide range of spinal disorders. These conditions include adult scoliosis; tumors; cervical myelopathy, or compression of the spinal cord in the neck; cervicothoracic kyphosis, an upper spine deformity; lumbar spinal stenosis, or narrowing of the space surrounding the lower spinal cord; spondylolisthesis, in which a vertebra has slipped out of place; and failed back syndrome, a chronic pain condition that can occur after spine surgery.

In research, Theologis' interests include assessing and managing risk for patients having surgery or revision surgery (a procedure to repair a failed implant), as well as managing complications after spine surgery. He is also interested in health policy, global health and educating the next generation of doctors.

Theologis earned his medical degree at UCSF, where he then completed his residency in orthopedic surgery, serving as chief resident in his final year. He completed a fellowship in adult and pediatric spine surgery at Washington University in St. Louis, one of the most prestigious fellowships in the field. He has also completed an orthopedics fellowship in Ghana through Health Volunteers Overseas, where he trained surgeons and operated on patients with severe spinal deformities.

Theologis has received local and national awards for orthopedic research, including the California Orthopaedic Association's J. Harold LaBriola, M.D. Resident Award; the Northern California Orthopaedic Society's Resident Research Award; the 2014 Most Outstanding Paper Award from The Spine Journal; and the UCSF Clinical & Translational Science Institute's Outstanding Resident Research Award.

      I am so impressed by Dr. Theologis' listening skills, ability to convey information, and skill in helping me to understand the reasoning behind his recommendations when they differed from my perception of potential next steps. I have had 4 surgeries on my back, and I felt I had a good experience with the surgeon who performed 3 of them. But I will say that Dr. Theologis is a superior communicator and gives me great confidence that I have selected a good surgeon and partner in my care.

      The surgeon and staff have been terrific, leading up to surgery, through surgery and now follow up appointments. I know that I have been an excellent hands and been well taken care of! I couldn't have asked for a better team.
