Dr. ARNAOUT was very informative. He was relaxed. He made me comfortable. He was clear in his explanation of the procedures. He gave me options to consider. And he had a great sense of humor and I would recommend him, highly recommend him. I was very pleased. I'm meeting him in person in a couple of weeks, so we'll enjoy a face-to-face rather than a virtual.

He is an excellent doctor. He looked at my scans before I got there. He was prepared and explained everything to me told me my different options and I was impressed that he had studied all my skins before I even got into the office.

Dr. Arnaout could not have been more compassionate, helpful, informative, and prepared.

I was truly am amazed with the level of expertise and professionalism. The doctors and the majority of the nurses provided. I was extremely impressed that my occupational therapist had the exact same procedure and was fully versed and knowledgeable of what I had to look forward to down the road.

The virtual visit with the doctor also included my son-in-law, [redacted] and my daughter, [redacted]. The doctor explained the need for a potential surgical procedure, and answered all questions about it that each of us had. He also said he was open to hearing from any one of us who had further questions and I will be getting back to him in the near future to potentially schedule the procedure. I am feeling confident with all that he explained to us.

My experience with male doctors in the past have not been great. So I'm always a little apprehensive when I have a male provider. But Dr. Arnaout was the complete opposite. I can't believe this guy's a brilliant brain surgeon and just so down to earth and kind. He listened. He went through every possibility of what could happen during the surgery to make sure I understood, and I was comfortable with it. He's just fantastic. I walked in there feeling very anxious about having a tumor removed from my brain, which is a very scary thing, and I left there feeling relaxed, happy, knowing that I was in good hands.

My provider was Dr. Omar Arnaout. I thought he was an excellent doctor. He listened to me. I listened to him. I think we had a great conversation. He devised a plan, kind of plan B, if you would, because of a pacemaker that I have. But he devised a plan, and I went along with that. I can honestly say I could express a great amount of confidence in him.

My reason for visit wasn't clear to him. Not sure if it was how the appointment was scheduled. He thought it was just a follow-up from an MRI that was done that showed no issues with a prior tumor. He was unaware that the reason for visit wasn't clear exposed hardware from this prior surgery. As soon as as I explained what I was there for, the appointment went smoothly.

I journeyed down to Boston from Vermont because the care in Boston has a great reputation. It was exhausting but worth the trip down as what I am dealing with is concerning. I felt welcome and cared for and could see that the physician was interested in everything I had been experiencing and have gone through. We are developing a plan. Which is more than what was happening where I am from. Second opinions, better opinions are important to me and my family.
