Debra Cassara

Debra Cassara is a partner at Ferguson Law Group, where she focuses on estate planning, trust administration, probate, and tax-oriented planning for individuals and families.

Before entering the legal profession, Debra spent over two decades in dental practice management, real estate development, and commercial leasing. That background gives her a practical understanding of how wealth is built—and where it can unravel without careful planning.

Debra’s practice centers on helping clients protect what they have built and pass it on responsibly. She advises on generational estate planning, business succession planning, and tax strategy for both individuals and closely held businesses. She also provides guidance on real property matters, particularly where they intersect with estate and tax planning.

Known for explaining complex legal and tax concepts in plain English, Debra works closely with clients to create plans that are both technically sound and realistically workable. Her approach emphasizes clarity, foresight, and minimizing the risk of disputes down the road.

Before practicing law, Debra taught ethics and scripture at Archbishop Mitty High School for over a decade, an experience that continues to shape her commitment to principled, client-centered counsel.

Mission Santa Clara de Asís was founded on January 12, 1777 and named for Clare of Assisi, the founder of the order of the Poor Clares. Although ruined and rebuilt six times, the settlement was never abandoned
