Well, the doctor told me what he wanted to prescribe me and when I went to pick it up at the Walgreens, I only had one prescription and the other one, the other two were never transferred to Walgreens and I'm waiting still.

I can't think of anything. I was very comfortable with Dr Berkley and I'm pleased he has joined your staff so much so I recommended my cousin see him

Everything was amazing, so I didn't say anything in the moment, and I should have spoken up for myself. However, I would have appreciated if my chart would have been looked over a little bit more. As I was transferred from doctor to x-ray to blood work, I don't know if they were handed the file or not, but I am allergic to adhesive, and after blood work, I was given a band-aid. I kind of just left the facility and took it off, but in the short walk from checkout to my car, I already had a rash on my arm from the band-aid. Granted, not a big deal. However, something like that definitely would have been noticed if my file had been looked at, or at least read, and if it wasn't documented, then obviously it wasn't the young lady's fault. She was truly amazing, and again, it was my fault for not speaking up, but that is just something I definitely think could have used a little extra work. Thank you.

This was my first time seeing Dr. Berkley and he told me of his background and experience. He also had read over my chart briefly so knew somewhat of my history. This made me feel very comfortable and confident with him. That meant a lot to me,

My doctore she was very quick to get me in the office even for a inhaler refill. I was told by nursing staff I could not get a refill unless I came into the office. I had just seen her several times that year and thought it was unacceptable for them to say I couldn't get a refill unless I came in. The office was over an hour away. I will never recommend that doctore or Prisma Health to anyone.

An exceptional doctor - attentive, caring, and truly professional. I want to express my sincere gratitude to this doctor. They pay remarkable attention to every detail, take time to explain everything clearly, and genuinely care about helping their patients. During the visit, I felt calm, supported, and confident - a quality that's rare to find. What impressed me the most is that the doctor never rushes, thoroughly examines the issue, and recommends only what is truly necessary. It's clear that they love their job and treat every patient with respect and compassion. I highly recommend this doctor to anyone looking for a skilled, attentive, and genuinely caring specialist. Thank you so much for your outstanding work!

I would like to say I was duly impressed by the courtesy, the cordiality of everybody. It was very impressive and I enjoyed coming there. The nurse made me feel comfortable before she started measuring my blood pressure and all that kind of thing. And the doctor was very observant and very courteous and cordial. I mean, there was nothing that could be better. So I'm pretty happy and I'm glad I'm at your facility for my health. Thank you. Bye-bye.
