Jeff L. Mangum

Of Counsel

Attorney Jeff L. Mangum is a powerhouse family law attorney and is one of the experienced members of Moore, Schulman & Moore, APC. For over 33 years, Jeff has provided his clients with expertise, strategy, and guidance regarding their divorce and custody cases. His experience regarding complex cases—including high-asset divorces and extremely contentious litigation—continues to make him a premier advocate among San Diego divorce attorneys.

Jeff was once a vital part of Gray Cary Ware & Freidenrich LLP, San Diego’s largest law firm at the time. He made a permanent impact on that firm’s reach, building its family law practice from the ground up and helping clients all over San Diego receive the solutions and outcomes they needed. Gray Cary Ware & Freidenrich is now part of DLA Piper—one of the largest global law firms in the world.

As a young attorney, Jeff completed all requirements to become a California State Bar Certified Legal Specialist in Family Law after only 5 years of practicing as a family law attorney—a certification that the majority of family law attorneys never attain in their careers. Becoming a specialist requires a combination of vast knowledge, extensive trial experience, and continuing education in the field. He has enjoyed specialty certification ever since.

Before joining Moore, Schulman & Moore, Jeff founded and managed his own family law firm for 21 years, a firm included in the Martindale-Hubbell® Bar Register of Preeminent Lawyers™.

Jeff is adept in all areas of family law. His depth of experience ranges from standard divorce, support, and custody proceedings to complicated, high-asset divorces and contentious custody cases. He also has experience in Hague Convention (international custody) litigation. Jeff is particularly known for his compassion, ethics, mediation skills, oral and written advocacy, and excellent legal analysis as he strives to meet his clients’ needs and best interests during an extremely difficult period in their lives.


For decades Jeff’s peers have given him Martindale-Hubbell’s AV® Preeminent Rating—the highest rating for professional excellence and high ethical standing. He has been repeatedly selected as one of San Diego’s “Super Lawyers”® and as San Diego Magazine’s “Top Lawyers in San Diego.” He has also served as a Judge Pro Tem and settlement conference judge.

Jeff is a passionate advocate for public education. He was elected four times to the Poway Unified School District (PUSD) Board of Education and helped make PUSD the educational powerhouse it is today. Jeff served PUSD for 16 years, retiring from the board after his daughters graduated. Jeff was also a recipient of a Master of Boardsmanship Award from the California School Boards Association and received various other awards and recognitions for his service.

A former Member of the Board of Directors for Project Concern International (a non-profit health and humanitarian aid organization), Jeff is currently on PCI’s Emeritus Council.
