This provider is a valuable resource to me and is adept at managing the neurological aspects of my complex medical condition. He is one of 2 key providers at MGH that I rely on to manage my health. I have been seeing this provider or 15+ years and I traveled back to Boston each year for an annual appt with this provider during a 7 year time period when I worked out-of-state. He is very knowledgable and quietly exhibits great compassion. I also value his adeptness with showing me my MRIs and seamlessly comparing multiple tests ad hoc to answer my questions. I was directed by a PC at B & W to visit the ER. It was this provider in the background who was giving direction to the Brigham for me. I realize how fortunate I am to have his care. I rely on his direction to jointly make decisions regarding my neurological health. He has great respect for my perspective, but also gives me a lot to think about and his direction. Thank you to this doctor.

I'm very happy with the care that I've gotten from Dr. Klawiter. He takes the time to listen and to answer questions. I was diagnosed a couple of years ago, but I still have a lot of questions about MS and what the different symptoms are and where everything is, and he takes the time to go through it to make sure I understand what is happening.

Dr. Klawiter and I had a Zoom meeting and first I spoke with an associate of his whose name I can't remember right now. Both were excellent. The associate took all my history and asked me a bunch of very insightful questions and then Dr. Klawiter came on, we discussed everything. I was very much reassured. We came up with a plan of action that involved some physical therapy. He pulled up an MRI scan, whatever you call it, of my brain and explained certain things. So very informative, very insightful and very reassuring.

I am extremely satisfied with Dr. Eric and his team of highly professional doctors. They not only know how to explain my MS, but they also try to help me understand my other medical conditions, which makes me feel extremely confident in having him as my primary neurologist. They are an extremely professional team that I would recommend 10+ times.

He was very attentive. We are seeing a different MS Dr now so I don't expect we will see him again. We are going to one we saw at mgh who has moved to Beth Israel.

I like Dr. Klawiter a lot. He is a good doctor, but he's not good with patients. [redacted] I often feel like he, you know, I'm an older patient, so I'm not as interesting to him. I just don't get a feeling of warmth from him at all. But I think he's a very good doctor. So I've got to balance that with his very starchy clinical manner.

I have been a patient of Dr Klawiter for close to a decade. He has helped me manage my MS through medications and ordering physical therapy when needed. When I see him we discuss alternative medications I might consider as well as future medications when they become available. I have complete confidence and trust in what Dr. Klawiter has to say.

I had written the wrong time on my calendar and was an hour late. I sent a message on the app saying that it was my mistake but I was going to go in in case they could meet with me. A couple minutes later his fellow entered the virtual room. Everything was fantastic. They were very accommodating and wonderful.
