Leslie J. Fineberg

Partner



In January 2026, Leslie J. Fineberg became a Partner at Grund Law, bringing decades of exclusive family law experience and respected leadership to the firm. Leslie has devoted her legal career entirely to family law and is widely recognized for her strength in both litigation and negotiation.

Leslie began her career as an Assistant State’s Attorney, focusing on parentage, support, domestic violence, and enforcement of Judgments for Dissolution of Marriage. During that time, she developed a reputation as a highly skilled trial lawyer. Her courtroom experience continues to be one of her defining strengths.

In addition to her litigation background, Leslie is a certified mediator. She combines strategic advocacy with thoughtful negotiation, often working to resolve complex matters efficiently when appropriate. Her years of trial experience allow her to negotiate from a position of confidence and preparation.

Leslie approaches family law with candor and clarity. She understands that divorce is often one of the most emotionally difficult periods in a person’s life. While many view divorce as the end of a family, Leslie works with clients to create healthier, more stable futures. She believes clients benefit from having a steady and honest voice guiding them through the process.

Her approach is direct and practical. Leslie focuses on fair and workable resolutions whenever possible but is fully prepared to litigate when necessary to protect her clients’ interests. Clients working with Leslie can expect informed guidance, transparent communication, and strong advocacy at every stage.

Leslie earned her Juris Doctor from the University of Miami School of Law in 1991. Since entering private practice in 1997, she has been appointed as a Special Assistant Attorney General on numerous cases, reflecting the trust placed in her legal judgment and skill.
