I spoke mostly with a resident, who took notes on my symptoms and medical history. He also performed a neurological exam. He was respectful and friendly. I talked with Dr. Harrold for less than 10 minutes, after the resident had compiled all my information.

This particular provider took time to notice about my kidney stones. Seeing all these other doctors nobody that's not his area of expertise went to emergency rooms misdiagnosed with epilepsy I don't know where that came from but now it's on my charts primary care physician I guess he's trying to help. But this guy here this doctor better than all of them can find I really appreciate his time. Haven't took a seizure since under his care greatly appreciated. But I do need help with mental health.

Dr. Harrold was very knowledgeable about my condition and provided my with information about treatment for this condition. He offered my hope. The Doctor from Mass Eye and Ear that botched my Laser eye procedure has given me little hope.

Dr. Harrold was caring, knowledgeable and prepared for my recent appointment. He explained everything clearly and allowed me and my family to ask as many questions as we wanted to. He did not rush or make us feel that time was an issue. He is a credit to the Neurology Department at MassGeneralBrigham. I would highly recommend Dr. Harrold.

I found the care provider very attentive and very good at listening and taking the time to understand what my issues were and addressing what the issues were and then providing helpful feedback and additional follow-up with tests and also a note that the labs were reviewed. So I thought it was a very thorough examination and I thought he was a very good provider when it comes to the relationship between a patient and provider. And I would highly recommend to anybody in my family to go see him. And I felt very, in very good hands and I felt like he really, really cared and understood and was able to help me.

He was great! Very knowledgeable. And he passed my name on to a study program perfectly in line with my issue. I left feeling much better and more hopeful now that I have a deeper understanding of my specific disorder. And he was able to rule out alzhiemers.
