It was excellent. Dr Callahan went over my lab work and answered all my questions. As always, she listens and gives me good insight and advice. I appreciate both her expertise and her empathetic, human manner.

I saw two different physicians today. Both appointments were awesome. On time. And they both spent time with me and listened.
