I have had the pleasure and honor of having, as my GP (for a loooong time), a true "Marcus Welby, MD." Dr. Pasternak is a gem. He listens, he engages, he knows my issues, he treats what limited issues I have. I always enjoy our conversations. It's not just taking info, entering it into a computer, and spitting out a report. It's a true doctor/patient relationship.

He is the best primary care anyone could have

He has been my primary care provider since 1993 and continuously provides the best care.

Dr. Pasternack is one of the most caring and dedicated physicians my son has ever been cared for. He is deeply devoted to his patients. He thinks thoughtfully about every approach. He takes the most conservative approach that is totally open to parental suggestions, and that is what makes it family-centered care. This physician is so incredibly kind, so renowned, so knowledgeable, and so compassionate. We are grateful to be under Dr. Pasternack's care. He's a world-renowned physician. He's one of the kindest people we have ever known.

Dr. Pasternack has been absolutely wonderful, caring, taking the time to thoughtfully go through everything. The best doctor we've ever experienced. The only struggle is access to him due to his only being assigned one nurse and his having to see so many patients due to his specialty.

Look, I just cannot say enough about Dr. Pasternak. He is just an incredible, incredible doctor and provider. My husband and I are so afraid if he ever retires because he has just been the best doctor ever. And I really hesitate to think that we could ever find someone like him who listens like he does, who cares as much as he does, who will follow up with us. like he does. He's just been really amazing.

Appreciate Mass General and my long-time provider. I respect and feel he has take good care of me.

Dr. Pasternack is EXCELLENT! He listened carefully to everything I had to say, then offered very helpful advice and suggestions. It's obvious to me that he really cares about his patients and wants to help them. He's a pleasure to deal with. Thank you, Dr. Pasternack!

My son has a very complex illness and we've seen over a dozen doctors over the past year and a half. Dr. Pasternack is by far the best specialist that we have seen so far. He really took his time with me during the appointment, making sure we went through the whole history. I never felt rushed. I do feel very confident in the plan that we came up with and I feel very fortunate that my child is working with him.

Dr. Pasternack went above and beyond my care. [redacted] I felt like I was indebted to my doctor because he did something for me other doctors can't or wouldn't do. So if 10/10 is the highest on your scale, I'll give him 20!
