MEET Diane Marcellino

diane2‘Law and Order’ is not just Diane Marcellino’s favorite TV show: it also describes perfectly her professional relationship with John Mulhall. He may know the law, but she’s the one who maintains the order! After all, she’s been keeping John in line as his legal assistant for over 18 years.

Diane is committed to making interactions with the firm as pleasant and efficient as possible. John calls her the firm’s “Director of First Impressions” since she typically handles the initial contact with prospective clients and the rest of the world. Diane has over 25 years of experience in assisting lawyers and their clients in family law matters, so she knows how challenging family conflicts can be, and she is well-equipped to assist the firm’s clients in their quest for resolution.

Known for being a bit of Florence Nightingale among her neighbors, as well as “mom” to three furry children (cats Justin, Jackson and Jake), Diane has developed a patience and empathy that routinely earns her the praise of her clients and other family law professionals. She’s also a mean bowler and an avid Florida Panther fan (along with Mike, her husband of four years), which means she’s not a pushover. In fact, her discipline and attention to detail make her an effective resource in any family law case.
