  • We discussed a plan going forward and reviewed the recent back surgery I had.

    2026-02-18

  • I have now been to three different ALS clinics since my diagnosis. By far, Dr. Barry was the most informed and experienced of all the providers that I have seen. He gave me more information about where I likely am in the progression of my disease and about possible treatment plans. Even though Boston is far away from Maryland, I am certain that this clinic is the right place for me to be. The level of care from this multi disciplinary clinic is worth the effort. It will take to travel there.

    2026-01-11

  • I always feel like I'm in good hands when I see Dr. Berry. He is so knowledgeable but yet down to earth.

    2025-12-20

  • He typically arrives late but stays as long as necessary to answer all my questions, and to demonstrate that he cares. He also ensures that people I need to see (speech therapists, his RN, and his PT specialist) visit with me after my visit with him (dr Berry).

    2025-12-20

  • Dr Berry tells it like it is. we appreciate that

    2025-12-16

  • The first person to see me introduced himself by his first name only. Later I asked for his last name. I don't know his status: ?Fellow,?Resident,??? In the world of medicine, Providers usually use their title/ credentials. He was great and so was Dr. Berry

    2025-12-22

  • All parts of care are fantastic....just a bit of chaos in and around the hospital, but that's expected, it's boston after all

    2025-11-17

    2025-11-04

  • For a diagnosis that is scary, and certianly not anything anyone wants to go through, I feel that my husband is in the best of hands with the team at MGH. I immediatley felt as though we had come in to an extended family.
