About Me
Roger Kasendorf, DO, is a board-certified osteopathic physician and physiatrist specializing in pain management, physical medicine, and rehabilitation. He practices in the San Diego area, treating patients across the full range of musculoskeletal and pain conditions, from acute injury to chronic pain that has gone years without resolution. Alongside his clinical work, Dr. Kasendorf teaches at three osteopathic medical schools, serves as a board examiner for his specialty boards, and consults on medicolegal matters as an independent medical examiner and expert witness. His practice rests on a principle held since residency: treat what a patient has lost the ability to do, not the label attached to their condition.
Roger Kasendorf, DO, earned a Bachelor of Science in Nutritional Science from the University of Maryland at College Park in 1999, an early sign of interest in how the body functions as a whole rather than as separate parts. He went on to the New York College of Osteopathic Medicine in Old Westbury, New York, receiving his Doctor of Osteopathy degree in 2003.
Dr. Kasendorf completed a traditional rotating internship at North Shore University Hospital at Plainview, followed by a residency in physical medicine and rehabilitation at Nassau University Medical Center in East Meadow, New York, where he served as Chief Resident from 2006 to 2007. He holds board certification from the American Osteopathic Board of Physical Medicine and Rehabilitation and from the American Osteopathic Board of Pain Management, and he is licensed to practice in California, Nevada, Texas, Wyoming, and Alaska.
Roger Kasendorf, DO has practiced physical medicine, rehabilitation, and pain management on both coasts. He operated his own practice, Roger Kasendorf, DO, PC, from 2009 through 2015 in Long Beach, New York, and La Jolla, California, and served as physiatrist and Director of Sports Medicine at Coastal Pain and Spinal Diagnostics in Carlsbad, California. Since January 2026, he has practiced with Ortho 1 Medical Group.
