Biography
John (aka Johnny Mac, the Rock Star Dentist) is unlike any other dentist. He is loud, obnoxious, and never seems to run out of energy. Recently, he’s taken up running Tough Mudder marathons and is excited to have a few showmances. Single and proud of it, if any girl wants more of a relationship, he has a sure-fire way of getting out of it—he'll start acting completely annoying and geeky, so they end up dumping him and no hearts are broken. He's a super-fan and wants to win so he can save his parents’ lake house and finally pay off his school loans. John gives out lots of dental tips and he says people like getting them.
