Our passion and purpose are clear: a commitment to working with clients and making sure to follow their estate plans according to their wishes. Meet our dedicated staff:




Karen founded Bishop Fiduciary in 2013 in order to provide trust and estate services to individuals and families in California, as well as a comprehensive suite of services that a corporate trustee cannot provide. Many clients need additional services to continue living independently in their home, or they need fiduciary services to protect them from others. Karen is able to offer both, and so much more.
Before 2012, Karen worked exclusively in wealth management divisions of several financial institutions in the Bay Area. She had the privilege of being introduced to the world of trust and estate services working at Citibank in 1997. While there, Karen worked closely with ultra-high net worth clients and their trusted advisors. Her clients were some of the most prestigious, well-educated and well-traveled who demanded the highest level of customer service.
In 2001, Karen began working with trust clients at Bank of the West. Many of her clients were successful, self-made millionaires. She worked closely with their trusted advisors to ensure services at the Bank coordinated with their estate plans. While at the bank, Karen also provided trustee services for special needs trust clients. She enjoyed working with such courageous families and developed many types of contacts and resources to make sure clients were able to live independently and safely in their own homes.
Karen moved to Mechanics Bank in 2007, where she honed her skills working with the Bank’s trust clients. She further deepened her financial and trust knowledge in order to be of service to and attentive to their particular needs, and continued to expand her resources so that she could also better service her special needs clients.
Before launching her financial career, Karen taught sociology at various colleges in Virginia and the Bay Area. Her love of learning and passion for teaching continues today as she works to educate and inform clients.
Karen’s commitment to teaching extends to the community. She invites individuals and families to contact her with any questions they have about their current estate plans. Karen can provide referrals for attorneys and other estate planning professionals as needed, and she is happy to review your current estate plans to make sure you are “trustee ready.”

Katherine’s finance background and legal education allow her to provide support as both a fiduciary and accounting assistant. Kathy has been a licensed professional fiduciary for two years. She currently acts as co-trustee with Karen L Fisher, the principal on many client accounts including trusts and conservatorships of the estate. Kathy is also responsible for managing the fiduciary accounting schedule to ensure all court-supervised accountings are filed on time. With over 16 years of mortgage financing experience, she has the ability to analyze complex financial documents. Katherine obtained her Juris Doctor Degree from John F. Kennedy University in 2016. During her legal studies, she assisted in both the JFK Elder Law Clinic and Family Law Clinics. She worked closely with seniors discussing estate planning goals and assisted in the preparation of estate planning documents including wills, trusts, and health care directives. Katherine also has a bachelor of science in Business Administration, Finance with a minor in Economics, as well as a Paralegal Certificate from California State University East Bay.
