James K. Leese

JAMES K. LEESE is a Senior Partner in the law firm FERRUZZO. Born in Dayton, Ohio, he was admitted to the California bar in 1979. The State Bar of California recognizes him as a Certified Specialist in Estate Planning, Trust and Probate Law.

In the early years of Mr. Leese’s practice, he focused on the areas of business and real estate transactions and civil litigation.  With that broad background, in the mid 1980's Mr. Leese practice switched to focusing on estate planning. Thus began the expansion of the firm’s estate planning footprint, stretching from one attorney to what are now many attorneys who are able to concentrate upon different aspects of the estate planning, estate and trust administration, probates and litigation, making FERRUZZO well known and respected within the Orange County community and beyond.  

These days Mr. Leese limits his primary practice to the transaction side of estate planning and business succession planning, serving clients, and their advisors, in a team approach, to recognize and solve the complex relational and tax issues which make up trust planning, succession planning, and estate and gift tax planning.  Mr. Leese continues to mentor and counsel the attorneys within the firm’s estate planning practice, and still serves the firm as Chair of the Estate Planning and (uncontested) Trust Administration Practice Group.

Since 1994, Mr. Leese has taught estate planning courses offered in the Personal Financial Planning Certificate Program at the University of California at Irvine Extension. He has been a guest speaker on succession planning, for the Cal State Fullerton’s undergraduate class on Family Business Dynamics. He has spoken to such groups as the National Business Institute, the Orange County/Long Beach Chapter of the California Society of Certified Public Accountants, the Arthritis Foundation, the Easter Seals Society, and to many civil service employees of many federal agencies, which have included the United States Airforce, Department of Homeland Security, Immigration and Naturalization, and Alcohol, Tobacco and Firearms.

Mr. Leese is married to Jennifer Leese, and together they have five children, Angela, Lauren, Alyssa, Ryder and Dylan.
