I was there for a full body skin exam. The exam was cursory and I did not feel it was thorough. No examination of the scalp, and a super quick glance all over. He didn't seem engaged, not much personality. Gave two options for fol up treatment and was hasty about wanting a decision right away. Didn't let me know when I should return before exiting the room

The physician came in the room with gloves already on his hands, which I felt was unsanitary. I also felt quite rushed during this appointment, and I don't feel like all of my questions were answered. He was backing out towards the door as I was asking questions, which, you know, is not a great feeling for a patient.

Dr. Marneros is an outstanding physician. He is a brilliant practitioner as well as a warm, caring human being, rare in any profession. Furthermore, he is meticulous in his examinations and, over the years, has diagnosed me exceedingly well. He explains his findings, makes recommendations, and is skillful in his treatments: superb physician and a credit to Mass General.

The receptionist at the front is a saint. There was a woman that came into the office who was giving her a hard time about scheduling an appointment and she didn't flinch and was very courteous.

It was my first time meeting him. I understand they were running behind on patients but my appointment felt rushed & felt like I was talking to a computer. He was very respectful but it was all so rushed, my main issue was acne & he glanced at my face & then immediately went into meditations/topicals. I had to ask questions on why he was prescribing me something because he didn't explain much.

The doctor was 30 minutes late to arrive and the only reason I had to see him was the requirement to sign docs before receiving PDT treatment. The doctor added no value, input nor help with the treatment that was left entirely to the nurse.

Dr. Marneros is great. I've always enjoyed seeing him. I see him every year, once a year annually, and he's easy to get an appointment with if you book it far enough ahead of time. He's always very timely, and he is a great doctor, and a great researcher. I think that MGH should continue to fund his lab, and in fact, they should increase the funding to his lab. Thank you.

I felt like the doctor was not making time for me and he just felt rushed and didn't ask me if I had any questions and I had a lot of questions and he was just like walking toward the door. He also was asking me about my tattoos in a judgmental way and was saying something about how I shouldn't keep getting more tattoos. He also was not really like answering my questions very thoughtfully. He was and he was using language that was like medical terminology that I didn't know. So I had to ask him to define it. And yeah, he just made me feel like he just wanted to be out of the office or out of the room and wanted nothing to do with me.
