As usual, I get the very best of care. I can always ask Dr. Lopes a question, and he does his best to explain it to me.

July 6, 2020 5:29 PM

It was a very good experience. That is why I came back!

March 16, 2020 2:40 PM

Dr Lopes and X are the best

March 16, 2020 2:40 PM

all great

February 4, 2020 6:17 AM

I was happy with the doctor and feel very comfortable with him and knowledge of his specialty.

January 21, 2020 9:07 AM

This provider identified a potential disease by examining my CT scan that the radiologist missed. He has done this twice. I am grateful. Either he is superior or the radiologist is incompetent.

January 21, 2020 9:07 AM

Long wait. First visit; 1 hour 45 minutes. Second visit; 1 hour 15 minutes. Both appointments had to be cancelled due to the doctor being needed for emergency surgery. Last thing. I had several conversations with the doctor's associates on My Chart. They're kind and caring ladies. However, one of them wrote information about my test that appeared to indicate a life threatening situation. I immediately responded and asked for further info. Nobody responded. I was living in terror for over a week until my appointment when I finally got the question answered. The nurses know I'm extremely depressed and anxiety riddled. It's terrible to tell someone they have a blockage of blood flow in their brain (wrong information) and make them sit and wait over one week for an answer.

I can only give the highest marks for Dr Lopes and his team. He has been my physician for over 15 years and he has always been compassionate and available for expressed concerns. it is his expertise as a physician that has kept me healthy and able to enjoy my life, and for that I am grateful.

January 13, 2020 9:37 AM

Dr. Lopes was a second opinion. I was VERY pleased with the care & clarity offered by him & his team.

December 12, 2019 12:42 PM

I feel that Dr. Lopes - took time to explain my condition and provided options to me and thoroughly answered questions that I had.

November 17, 2019 11:00 PM

Dr. Lopes and his team are wonderful. Dr. Lopes is a brilliant doctor. You are lucky to have him on your team. Please do your best to keep him.

November 17, 2019 11:00 PM

Besides being knowledgeable he is caring, compassionate, and listens to his patient. The best neurosurgeon!

November 3, 2019 6:00 PM

Due to some emergencies, Dr. Lopes was extremely late. The staff kept me informed, and Dr. Lopes was extremely apologetic. Dr. Lopes then took a long time with me. I felt he cared about me and my time, but wanted to be sure that I totally understood my situation and options.

August 16, 2019 7:00 PM

Dr. Lopes makes me feel comfortable and calm.the staff that works with Dr. Lopes is outstanding.

August 15, 2019 7:00 PM

August 8, 2019 7:00 PM

Dr. Lopes MD, is outstanding - reviewing & explaining my health situation, options, what to do!

July 29, 2019 7:00 PM

Dr. Lopes is always respectful, cordial, & takes time to answer any questions my husband and/or I have. Dr. Lopes explains the results of the tests in a manner that my husband & I could comprehend. Dr. Lopes completes all the paper work necessary for my medical leave.

July 26, 2019 7:00 PM

Good care.

July 14, 2019 7:00 PM

Excellent neurologist!

July 14, 2019 7:00 PM
