    Clinician didn't explain what the implications of the 2nd X-rays were. He said I could remove my brace, but had no advice or cautions on how to proceed. It was rather dismissive.

    I'm unsure how much he knew about my injury. He came in, said cortisone injection and sat down at the computer.

    William is terrific, eased my worries when I was very nervous about the procedure. Talked to me through the whole procedure to distract me which was so helpful.

    I felt I had to ask questions that should've been brought up in the first place, bending/weight barring. Had different information then my Surgeon on the degree of which I can bend my knee and weight barring limitations. Nice guy just felt sort of dismissed.

  • About William Marshall, PA-C

    I served as a medic in the U.S. Army for 20 years before studying to be a Physician Assistant at the University of Washington. Working with great physician assistants inspired me to help patients, focusing on sports medicine and joint injections. I specialize in sports medicine, focusing on helping athletes return to their sport. I enjoy operating room procedures and joint injections. My aim is to be a competent, compassionate, and efficient provider for my patients.

    Philosophy of care

    I believe in a team approach, with the patient's needs being the most important thing.
