Skilled litigator, problem solver, superhero – these are just a few words to describe Lisa. She can solve any client issue thrown her way with gusto, giving it the dedication and attention it needs. Not only does she lead her team with tenacity and confidence, she gets everyone up to speed on the latest in the industry and ensures that they keep up the pace. Can you keep up with Lisa? We hope so.

A master of leadership and dedication, Lisa works to reduce risk and help her clients cope in a crisis. Suffice to say you will want Lisa in your corner not only for the next apocalypse, but for all your cyber and complex insurance litigation needs, including class actions. Her background in healthcare and professional services makes her uniquely positioned to be the cyber security superhero you deserve.

The A in SBA, Lisa is also the firm’s managing partner. As the eldest of 8 children from a blended family, Lisa knows a thing or two about leadership, diplomacy and teamwork. She manages the firm much like she did her siblings growing up: gentle persuasion mixed with the occasional knocking of heads.

When she isn’t herding cats, Lisa is winning hotly contested accident benefit and bodily injury “CAT” claims at all levels of Court and administrative tribunals.
