Everyone who meets Peggy Elliott becomes a friend.
Although Peggy’s allegiance to her alma mater (Michigan – Go Blue!) was storied, her love and commitment to Sonoma County and to her clients ran even deeper. Peggy’s practice was focused on Estate Planning and Trust Administration and over the years she handled work for multiple generations of Sonoma County families and businesses. She excelled at complex estate tax matters.
Every client of Peggy’s was her favorite.
In addition to her practice, Peggy also gave much to the community: she was a long-time Board member of the Santa Rosa Symphony, and served on the Boards of numerous local non-profits. She has continued her volunteer work with 4Paws, visiting health care sites with her beloved Scottish Terriers, offering social therapy to those in need

After a career that spanned more than 40 years, Don retired in December of 2022.
Don came to Anderson Zeigler after being a long-time solo practitioner in Santa Rosa. Not only did he bring his tremendous experience as a real estate and business transactions lawyer to the firm, but he also readily shared his deep insights and knowledge. Don was always available to brainstorm with colleagues and enthusiastically serve as a mentor to the firm’s less practiced lawyers. We had no idea that a solo practitioner could be such a team player!
Don immediately made an impact on the firm’s culture and operations, becoming a co-managing director in 2016.
His enthusiasm for the practice of law and his excellence at problem solving served countless business clients in a wide range of matters from finance to employment law and complex real estate transactions. His practice also included a focus on the hospitality industry.
