How likely are you to recommend Dr. Lanis?

(Select your rating)
My daughter visited Dr Lanis for the first time after her recent stroke/hospitalization and he was awesome. He ran a little late but after all the time he took with her I could understand why. He was very thorough, took lots of time with her/us, going over her medications, recent hospitalization. I can't say enough good things about him. Thank you
