Where Tradition Meets the Future®


Christina “Christy” O’Brien, now a Florida Supreme Court Certified Family Mediator, serves as the firm’s Divorce, Marital and Family Law Department Chair. Her practice includes all types of family law matters, including divorce, alimony, timesharing, paternity, domestic violence injunctions, post-judgment modifications and adoption issues. In addition, she also drafts and litigates prenuptial and postnuptial agreements, making her a tremendous resource for those facing family law issues.

Family law cases often involve challenging parenting issues; perhaps health and wellness issues exist involving alienation or substance abuse. If a family business is concerned, business valuations and marital assets and income tracing would be necessary.

Christy understands that family law cases can be highly emotionally charged, especially when children are involved. Relying on her experience, Christy develops customized parenting plans and marital settlement agreements tailored to the needs of each family. She is also an appointed Guardian Ad Litem in Lee County and certified to make recommendations regarding parenting plans that would be in the child’s best interest. 

Christy has handled and tried jury and non-jury trials throughout her career in the Twentieth Judicial Circuit (Lee, Charlotte, Collier, Hendry and Glades Counties) and the Twelfth Judicial Circuit (Sarasota, Manatee and DeSoto Counties) Florida. She is admitted to practice in all Florida State Courts and the United States District Court for the Middle District of Florida.

Naples Illustrated magazine named Christy to its “Top Lawyers” list for her work in Family Law for the years 2020-2023, and she was included in the 2024 edition of Best Lawyers in America® for her work in Family Law. Before joining Henderson Franklin, Christy managed her own practice in Fort Myers where she handled family law and civil cases.

Christy resides in Fort Myers with her husband and three sons. She enjoys running, traveling, and boating with her family in her spare time.
