Dr. B remembered my medical history and birth preferences from the first to last visit, and demonstrated complete respect for me and my partner. When I needed him to, he took time to sit down and talk through the pros and cons of different treatment options, allowing me to make an informed choice. I left another OB practice to become a patient here and I am so glad I did.
Dr. Buchanan is excellent! Anytime I have seen him over health issues he explains things in a manner in which I understand. I feel fortunate to have such a great doctor and for so many years.
Again, since this is my "yearly" woman appointment - would love to be treated like a patient -not just a number - that has to be seen within 15 minutes and then expedited. I would rather wait 30 minutes, and then get to have quality time with my Dr.
I so appreciate Dr. Buchannan's style. He always starts the conversation about asking how I am and then follows up by asking about my boys (that he delivered). He always refers to them by name and inquires about school/sports. Such a nice touch!
