    Doctor McKinstry performed my previous knee replacement. I trust him with my next surgery as well.

  • Feb 29, 2024

    MedStar in fortunate to have Dr. McKinstry. He's a 10 out of 10 physician. Bedside manner and office manner are excellent.

  • Feb 23, 2024

    Dr. McKinstry explained my X-ray results and performed a quick but thorough examination. He provided me with clear recommendations for the next two months until my next appointment. I asked his opinion about a potential trip later in the year, and he suggested ways that I could increase my traveling comfort and maximize my ability to enjoy the tour.
