Years of Experience

Michelle May O’Neil has 24 years’ experience representing small business owners, professionals, and individuals in litigation related to family law matters such as divorce, child custody, and complex property division. Described by one lawyer as “a lethal combination of sweet-and-salty”, Ms. O’Neil exudes genuine compassion for her client’s difficulties, yet she can be relentless when in pursuit of a client’s goals. One judge said of Ms. O’Neil, “She cannot be out-gunned, out-briefed, or out-lawyered!”
