Very quick and efficient, did not have to wait an hour to an hour and a half after my appointment time like other places in the area, actually got in early and got out the door 2 minutes after my appointment time. Very highly recommended.
Dr Zachary Ryan took me right in with no appointment no problem he said he was very professional I’m usually very nervous in offices as a truck drivers aren’t comfortable in dr offices he was great I’m telling everyone he is the best see him!
Dr. Zachary Ryan was very professional curious and nice. The building and their office is very nice. I got my CDL medical card renewed with Dr. Zachary Ryan. I will be returning here when it is time to renew my medical card again. I will be recommending their services to others.
If your for a friendly and professional staff look no further….The receptionist was knowledge and pleasant….The was kind and patient. No long lines no excessive waiting, in and out with no problem. I definitely would recommend anyone to try their services…Thank you.
