This was my first appointment with MGH Neuromuscular and the doctor had read my fairly extensive medical history and was very prepared for our appointment. That is rare in my experience, and impressive. [redacted] the provider was very well prepared and spent a lot of time with me. Nothing was rushed. He was very good.

Dr. Joshua treats me like I was a family member. I'm so fortunate to have him on my MGH team of amazing Doctors Surgeons, and nurses that I have, and Surgeons I've had.
