    *Dr. Buchanan is my GYN and I see him once a year for a wellness check up. He is a great doctor.
    I used the portal to E-mail to ask a question. *Dr. Buchanan answered promptly - No need to call.
    Fast, friendly and efficient. I know I will get in on time and Dr Buchanan will answer any concerns I have. I never feel rushed or ignored.The front desk person was very friendly and efficient. I understood exactly where to go and what to do. Always the easiest appointment of the year.
    I was very pleased that Dr. Buchanan had reviewed my medical records before my visit and referred to them in our discussion. Being prepared is very important.
    I couldn't be more happy with the staff or Dr. Buchanan. The staff are polite and helpful and Dr. Buchanan always makes me feel comfortable. He was a patient advocate for me when I was referred for problems with my vision (during pregnancy) and couldn't get an appointment sooner than 2 months away. Dr. Buchanan called the office and got me in that week with the specialist. I couldn't ask for a better experience in my first pregnancy!
