• Dr. Zacharias was very detailed in his explanations, very easy to talk to, and answered all our questions, and he saved my fathers foot. He did exceptional work on my dad and restored blood flow to his leg. His medical assistant, who was heading to medical school, was also very detailed and easy to deal with. Both of them exhibited a lot of compassion and care to my dad which was very appreciated. even the front desk person was kind.

• I wish the time with him was a little longer . He is very nice , but a bit rushed .

• I think he's a good doctor overall and very professional. It's just that I felt he was a bit rushed and didn't take enough time to answer all my questions. He also told me there was only one option for my varicose veins, a procedure involving injecting medication while I was sedated under anesthesia, and I would have liked him to explain more options to me. Perhaps it was because I was the last appointment of the day, but at my next appointment I'll try to insist on finding out more.

• He was 45 minutes late but that was very acceptable as to me. It meant if patients had questions he stayed and answered them to me that is the sign of a good doctor.

• Dr Zacharias is extremely thorough and knowledgeable. He took the time to listen to me; he reviewed my medical history; he gave a great deal of thought to determine the best and safest way to approach treatment for a complex case. He is very caring, patient and personable. He is very respectful and thoughtfully considered my input. I felt heard and felt that he valued my input. He is extraordinarily intelligent and capable. He is carefully looking out for my safety. I am terrified by the complexity of my health issues and my current health conditions but I am extremely confident that I am in the best hands possible with Dr. Zacharias. I trust him with my life. Zacharias is an outstanding person as well as physician. I am extremely grateful that he took me on as a patient. Thank you for this opportunity to express my gratitude.

• When I spoke to Dr. Zacharias, he was very professional and personal and was very easy to talk to and relieved me from my being afraid quite well.

• The physician was fantastic, I would recommend him and his staff for anyone I know that is looking for such a specialist. He was exact, open minded, excellent communicator. He was excellent in the medical services he provided to me. I was nervous and he took the time to explain to me what was going on and what he was doing to handle the issue I brought to the department. [redacted] I just can't say enough about the services I receive and continue to receive at MGH Mass General Brigham, By far the best in the World!! [redacted]

• This provider, Dr. Nikolaos Zacharias, is one of the best providers I've dealt with at Mass General. And mind you, I work at Mass General in the neurology department. He is amazing. He's courteous. He's always on time when I need to be there. Sometimes he's there before me. So I appreciate him. I appreciate his coordinator, Adrian, who always calls me to make my appointments and everything that I need. Keeps me in touch with the doctor. And I just met Nurse Jamie, who's also amazing.
