Ann Deuel MacArthur, Partner

Ann MacArthur, Holsman & MacArthurAs an estate planning, trust and probate attorney, Ann MacArthur’s practice is dedicated to helping families, individuals and business owners identify and reach their estate planning goals.

“It’s a complicated subject, and I do my best to explain tax and legal matters in plain English, so that clients can make informed decisions,” says Ann.

“I help clients in San Francisco and Marin anticipate estate issues with their kids and parents and steer them away from potential pitfalls in their estate planning, as well as discussing how to maximize their gifts to charity,” she says.

“One of the biggest assets I offer clients is my real world experience. I come from a large family and have seen how siblings and parents and grandchildren interact. I am also a parent, so I understand the issues and concerns of parents with young children.”

Professional background
Ann is a second career attorney, having spent several years managing finances in the software industry, during the boom and bust. She has worked with start-up companies, small businesses, artists, filmmakers and nonprofits. She was also a business owner, and draws on all of her experience to help her clients achieve their estate planning and business objectives.

She was admitted to the California Bar in 2007, after attending University of San Francisco School of Law. She is a member of the Marin County Bar Association section on Probate and Estates, the Bar Association of San Francisco and the State Bar of California.

On the personal side
An outdoor enthusiast, Ann enjoys hiking, backpacking in the Sierras, camping, kayaking and mountain biking — especially with her kids. She is a fan of classical, bluegrass and choral music, and serves on the board of The Pocket Opera. A volunteer for the County of Marin, Ann speaks to senior groups on how to prevent elder financial abuse.
