    He is the only doctor I have had in decades that will listen to all of my issues and I’m not limited to one per visit. He is extremely knowledgeable and relays information in an easy to understand manner. He and his staff are also quick to respond on the portal.

    Like I said he is very personable. Seems competent. Answers my questions amiably. I feel like we have a good rapport and I’m comfortable with him. I just wouldn’t necessarily recommend him to someone I know. My friends and relatives have their own doctor in whatever medical group they are covered by through their respective insurances.
