Meet Our New Trustees

Amber Berrios ’07

Amber Berrios ’07 has been working in finance and real estate since 2011. She currently serves as Vice President & Associate Director at Majestic Realty Co. She received her B.S. in public policy, management and planning and her M.S. in planning from the University of Southern California. She serves on the Advisory Council at the Hispanic Scholarship Fund, and is an active member of the Catholic Association of Latino Leaders – Young Professionals and USC’s Latino Alumni Association.

Amber recalls instantly falling in love with Mayfield on her first visit. She says, “I distinctly remember driving down the driveway after Open House feeling convinced Mayfield was the perfect fit for me.” As a student she remembered the “special unity Mayfield created” and the “respect and admiration” she felt among students. Amber had a “wonderful experience” at Mayfield, and as a new board member, she aims to help foster an environment where every student feels accepted, welcomed and able to access the many opportunities she enjoyed. Amber feels strongly that “Mayfield is a place that allows you to grow and explore who you are, creating confidence in a place full of support, while still keeping you aware of how you can give to the world.”

Wellington Choi

Wellington Choi grew up in the San Gabriel Valley and graduated from the University of Southern California with a business degree. He’s currently a senior vice president in sales and distribution for the investment firm Capital Group. He lives with his wife, Felicity, in San Gabriel with their two kids: Andrew, a recent St. Francis High School graduate who is headed to the University of California, San Diego this fall, and Jessica ’23, a rising junior at Mayfield. His volunteer work has included AYSO, Little League and Boy Scouts of America.

As a product of single-sex education, Felicity Choi championed the same approach for their kids, which made the family intentional in their high school searches. Wellington says, “On the surface Mayfield looks outstanding—the staff, the students and curriculum,” but, he adds, “to know an organization, you have to look behind the scenes.” He has been serving on Mayfield’s Finance Committee and after having “an in-depth look at how meaningful decisions are made and budgets are set,” Wellington was impressed, especially with the way COVID-19 aid was distributed to families this year. All of this, he says, “reinforced that this was a high quality institution.” Although Jessica spent most of her sophomore year in remote learning, Wellington already sees that Mayfield is a place where she will grow in “confidence, independence and compassion.”

Alison Jones Gamble ’87

Alison Jones Gamble ’87 has served as President of Gamble Jones Investment Counsel since 2011, having started at the firm in 1993. Her mother, Virginia Schlueter Jones ’64, is also a Mayfield alum, and Alison has fond memories of being on the Bellefontaine campus when she was young, saying that Mayfield was “always where I wanted to be.” Alison received her B.A. from the University of San Diego, and she lives in Altadena with her husband, Mark, her son, Matthew (17), and daughter Grace ’24. She has served as a board member for the Cancer Support Community, and has been on the Mayfield Junior School Board since 2012, serving as board chair from 2019 to 2020.

Though Alison’s time at Mayfield was overwhelmingly positive, it was also marked by tragedy. A few days before her junior year began, her tennis doubles partner, Maureen Shea ’86, died in a car accident. “Our tennis team was one big family that rallied around each other during [that] difficult time,” says Alison, adding that they “spent a lot of time before matches in the chapel.” In spite of the extraordinary grief felt by the community, the team won the CIF Championship and dedicated its victory to Maureen. Alison’s daughter, Grace, has also had her Mayfield journey shaped by larger forces—in her case, a global pandemic. Alison strongly believes that the Holy Child mission, and the tremendous support system within the school, help every student to become “a much more well-rounded human being,” and asks sincerely: “How could you not be inspired?”

Brittney Dennis Pruitt ’03

Brittney Dennis Pruitt ’03 serves as Division Vice President, Corporate Controller of Pharmavite LLC, where she oversees the day-to-day finance operations and is responsible for corporate accounting. She has served on the Audit Committee at Mayfield Senior School since 2009 and assumed the role of committee chair in 2019. Brittney met her husband, Lawrence Jr., when they were in elementary school at Calvary Christian, and after falling out of touch for years, they reconnected after she finished her degree in business administration at the University of California, Riverside. They live in Altadena with their 2-year-old son, Lawrence III, and enjoy outdoor adventures as a family.

A sense of warmth initially drew Brittney to Mayfield and inspired her to return long after graduation. “Actions Not Words” continues to motivate her, and she says she applies “that motto in every facet of my life.” But her high school experience wasn’t straightforward. She attended Mayfield her freshman, sophomore and senior years—electing to enroll at Monrovia High School for her junior year. She had already made “lifelong bonds” at Mayfield, but she also was keenly aware of socioeconomic divides and sometimes felt out of place, saying, “I didn’t see a lot of people who looked like me.” Brittney’s year away from Bellefontaine gave her perspective, and helped her to discover what she deeply appreciated about Mayfield and, ultimately, make the decision to re-enroll. She supports Mayfield’s ongoing justice, diversity, equity and inclusion initiatives and believes the availability of a similar toolkit might have led to her staying at Mayfield as a teen. Drawing on her own unique experiences as a student, Brittney hopes to foster more journeys of belonging as a board member. “We’ve made so much progress, and there’s still progress to make,” she says. “I’m just really excited for what’s to come in the future.”

Ryan Squire

Ryan Squire has practiced as an attorney throughout California and the nation for over 22 years, primarily in real estate litigation and appeals. He received a B.A. in political science from the University of California, Riverside and his Juris Doctor from Pepperdine School of Law. He lives in Monrovia with his wife, Jennifer, and their three children, Colin (UCLA ’23), Caroline ’23, and Maddie ’25. He is currently in the theology and Christian ministry master’s degree program at Franciscan University of Steubenville (Ohio), and hopes to teach part-time while continuing to practice law.

Ryan admits he didn’t know much about all-girls’ schools and, initially, his elder daughter, Caroline, wanted to attend Monrovia High School to stay with her friends, but visiting Mayfield changed her mind. “Looking back,” Ryan says, “I think God had this in store for her.” Aspects of Mayfield that continue to inspire Ryan are the “whole child” approach and the school motto of “Actions Not Words.” Ryan credits Mayfield for much of Caroline’s maturity in approaching the complexities of “religion, theology, politics and social justice,” and he’s impressed by “how she has grown into an...empathetic person who advocates for herself and her friends.” Ryan takes particular delight in the fact that “Caroline absolutely loves going to school” and is overjoyed by daughter Maddie’s excitement about starting as a Mayfield freshman.
