Dr. Matiello is the beat neurologist one can have. I am always impressed that he has residents with him and that actually meeting clients and watching how he works is the best way to learn. He is excellent. Easily a 10 or more. A l ways a positive and constructive experience. Understands balance of pat I ent management and knowing he is monitoring all aspects of one's heakth related to neurology and recognizes both the cognitive aspects aling with social and connection to the rest of the human body.

Dr. M is very professional and provides us with information using the data from my MRI. Dr. M also gives us insight into our future care with respect to our autoimmune conditions. Dr. M was pleasant also interacting with us socially, before and after, addressing my medical condition making our experience coming to Boston worth the visit. Our understanding and feeling towards Dr. M is that he is a very qualified specialist in the Neurological field of medicine. We have full confidence in the care he provides for me.
