He is great.
Dr Buchanan was SO nice! He really listened to my concerns
*Dr.Buchanan is quick and efficient (which I like), while still being thorough.
dr Buchanan is a very congenial guy, but he barely spends 5 min with me. In fairness he does answer any and all questions I have, but he doesn't really go over what I could expect to feel during certain weeks of my pregnancy in great detail, or go over my test results, explain the genetic test options to me.
Routine check-up, so no problems to address.
