Who is Kristi Gates?
Kristi Gates was born Kristianne Gates in 1954. She is the first child of William H. Gates Sr. and Mary Maxwell Gates. As the oldest sibling, she set a high bar for the family. While her brother Bill became a global icon in technology, Kristi built her own path as a respected financial expert and a leader in her community.
After marrying her husband, John Blake, she became known as Kristianne Gates Blake. She has spent most of her adult life in Spokane, Washington, where she is known not just as Bill Gates’s sister, but as a pillar of the community in her own right.

The Gates Family Foundation: A Legacy of Service
To understand Kristi Gates, you must first understand her parents. She is the daughter of two very impressive people who believed success was not just about what you earned, but what you gave back.
Mary Maxwell Gates and Kristi Gates
Her mother, Mary Maxwell Gates, was a force of nature. She was a successful businesswoman who served on the boards of major companies, including IBM. She was also a strong believer in charity. She spent many years working with the United Way, and she taught her children that they had a duty to help others. This lesson deeply shaped Kristi Gates‘s life.
William H. Gates, Sr. and Kristi Gates
Her father, William H. Gates, Sr. (also called Bill Gates Sr.), was a prominent lawyer in Seattle. He was also a strong community leader. After he retired from law, he helped his son start the Bill & Melinda Gates Foundation. He guided its mission for many years. Growing up, Kristi Gates saw both of her parents work hard and serve their community every day.
The Three Gates Siblings
The Gates household was a busy and competitive one. The three Kristi Gates siblings—Kristi, Bill, and their younger sister Libby Gates were raised to be smart, curious, and to always challenge each other. Bill Gates has often said that he learned a lot from his sisters.
While Bill found his passion in computers, his sisters found different callings. Kristi Gates went into finance, and Libby Gates became a therapist. All three children, however, share the same strong commitment to philanthropy that their parents taught them.
What is Kristi Gates’s Job?
This brings us to the main question: What does Kristi Gates do for a living? The Kristi Gates job is one of high-level finance and accounting. She is a Certified Public Accountant (CPA).
She graduated from the University of Washington (her parents’ alma mater) and began her career at the major accounting firm Deloitte, Haskins & Sells. She was very successful and eventually rose to the position of partner at the firm. This is a very difficult and impressive achievement in the financial world.
A New Path in Spokane
In 1987, Kristi Gates decided to make a big change. She and her husband, John, wanted a different kind of life than the one offered by a huge corporation. They made a “lifestyle decision” and moved from Seattle to Spokane, Washington.
In Spokane, she started her own private accounting practice, called Kristianne Gates Blake, P.S. This move allowed her to work directly with clients, helping them with financial planning. She even co-wrote a book in 1989 called “Stop Fighting about Money and Start Making it Work for You.” This shows her passion for helping people understand their finances.
A Life of Philanthropy and Leadership
While her job is as a CPA, a huge part of what Kristi Gates does is public service. Following her mother’s example, her list of volunteer work is incredibly long and shows a deep love for her community.
She served for 12 years on the University of Washington Board of Regents, one of the most important leadership roles at the university. This was a position her mother and father had also held.
A Community Pillar
Her work in Spokane is even more impressive. She has served on the boards of many organizations, including:
- United Way of Spokane
- YMCA of the Inland Empire
- Junior League of Spokane
- Community Colleges of Spokane Foundation
She also used her financial skills by serving as a director for Laird Norton Wealth Management. This work shows that Kristi Gates did not just join a famous family foundation; she put in the hard work herself, in her own town, for decades.
