    Dr Leder stays up-to-date with the latest in osteoporosis research, and together with his empathy for his patients, it translates that into the great care. Doesn't get better than this!

    Both providers were excellent. They listened carefully to the many layers of my medical problem, including many fractures and were open to thinking outside of the box to help me come up with a solution. I feel lucky that I can get my care at Mass General!

    I am so glad that I insisted on getting a second opinion from a specific doctor who deals with this specific condition. He was so knowledgeable with what I was looking for information on. Only wish I had all the information he needs so it's going to take longer to complete the ongoing questions I have!

    During this visit I saw Dr. Leder and Dr [redacted]. Both were extremely helpful and empathetic given the nature of my situation. They made sure I understood my options and what would lay ahead for me. I continue to work with Dr [redacted] and receive regular updates following the status of my tests. I am very grateful for the care I received through this office.

    I have osteoporosis and I've been seeing Dr. [redacted], who's no longer seeing patients, and he stepped in very competently, and I'm very comfortable. So I think it was a very good transition for a complicated case. Thank you.

    Excellent medical care. Scheduling is a little inflexible, but the care I receive makes this a small concern

    The doctor did an excellent job explaining the treatment options. The unknown at that point was the cost of this tier 4 injection which is rather high. We will investigate other available options.

    Hi, Dr. Leder was very thorough. He went over my bone density test that I had had earlier that day and explained the changes from my last one. He explained the course of action that we're going to take and he asked if I had any questions and answered my questions. He was very professional and thorough and excellent care from him and his staff.

    Dr Leder can assess test results quickly, and he listens carefully. His knowledge of osteoporosis medications is impressive. He consults with nurses about insurance coverage for medications so his treatment plan can move forward for his patients. I have the utmost respect for his expertise. Thank you. [redacted]
