Mario, a new resident in the Angels Memorial ER, has top-of-the-game medical skills, but could use a little help with his people skills. Italian-American, cocky, and devastatingly handsome, Mario grew up in a tough neighborhood and bootstrapped his way to becoming a doctor, working second jobs to pay for medical school. Mario has boundless energy and plays to win. Succeeding is the only option for Mario. But because he’s only ever relied on himself, Mario has a few lessons to learn about teamwork if he’s going to make it through the residency program (and make friends).
