Sometimes he would start talking about a treatment or study I wasn't aware of, but always clarified when I asked questions

National Jewish Health PatientJune, 2020
Dr. Lanser is friendly and kind and talks in plain English. I like that. I do get the feeling that he doesn't like to wait, so sometimes I don't ask all my questions because they're not on the tip of my tongue. [related to another provider]

Dr. Lanser is very friendly and listens to all concerns. He answers questions in a very thoughtful and easy to understand manner. He is great at engaging children on their level. I have recommended him to others when they are looking for an allergist.
