Jason A Efstathiou, DPhil, MD

All good

This doctor was very nice. However, I was in a state of severe anxiety and I hope that I did not seem disrespectful. I was simply having a hard time focusing. Please let this doctor know if possible.

Jason Efstathiou Is awesome! he is very patient, knowledgeable and considerate. One of the best doctors I have ever met!

Excellent care by excellent providers thank you

They make an unpleasant situation tolerable.

I felt that he listened and understood my concerns and was thorough.

My experience with Dr. Efstathiou and his team at Mass General has been nothing short of exceptional. I've always had the opportunity to ask as many questions as I needed to. With a disease like what I had and slash have, there's some sensitive conversations that need to happen. Whether it was a nurse or Dr. Efstathiou, I always felt comfortable with asking the questions that I wanted to ask. And overall, extremely happy with the care that I've been provided by Dr. Efstathiou's office and himself.

Very professional and knowledgeable.

I am very grateful for the great care I am receiving.

I am very pleased with the doctors and the nurses at Mass General. It has been an excellent experience so far.

This is precisely the kind of experience that makes me grateful to live in this area of the world and to have access to MGH for my medical needs. Thank you!

A quality professional experience.

Always had a great experience with all the providers, nurses and techs at MGH

I think Jason is an excellent doctor particularly in his field of expertise. I chose him specifically after visiting top practitioners in his field and because of his ability to explain the disease and differentiate treatment options within radiation possibilities. Furthermore his ability to differentiate and answer questions about post "surgical" complications was very helpful. One other motivating reason for selecting Jason was that several of the doctors I spoke with in leadership positions in different regions of the country when queried about their education and training were students of Jason. All advised I would be in good hands with Jason and his team.

I am very satisfied with my radiation oncologist Dr. Jason Efstathiou.
