Mendel is a Yiddish-American Jewish man who lives in New York City with his wife Trina and stepson Jason. His advice is a bit nonsensical and strange. He cares deeply for those he loves and gives good emotional advice to his family. He's a bit self-centered, forgetful, obsessive, and inappropriate, even when dealing with patients. People think he's annoying, talkative, and a mansplainer. He's awkward when nervous or flustered. He is a short insomniac.
