About me

Copenbarger & Copenbarger LLP. began in 1979 when Lloyd Copenbarger was admitted to practice law in California and opened a firm known as Copenbarger & Associates. Since that time, Lloyd and his associate attorneys have provided substantial services in the personal estate planning and business succession planning areas and have helped thousands of people to create estate plans that include contributions to their favorite charities. Throughout the years, the firm has seen many changes, and is now comprised of three full time attorneys and one additional attorney who is of counsel to the firm, and it continues to grow. However, despite any surface changes, one thing has always remained constant: Copenbarger & Copenbarger LLP provides clients with excellent legal services in personal estate planning and other related fields.


James M. Kosareff is an attorney practicing estate administration, probate, and tax law in the firm’s office.
