The founder and president of Impact Family Office in Santa Barbara, Kiah provides independent
trustee and family office services to individuals, families, trusts and private foundations. A
California Licensed Professional Fiduciary, he serves as a professional trustee, and dozens of
families have selected him for current and successor fiduciary roles.

Kiah focuses on thoughtful stewardship of multigenerational wealth. He helps families navigate
complex trusts, succession and estate transitions, family governance, philanthropic engagement
and the responsibilities of significant financial resources. His multidisciplinary team provides
accounting, administration, reporting, planning and professional coordination for longtime
support of families and beneficiaries.

He believes stewardship extends beyond financial performance and encourages families to
reflect their values in their decisions, relationships, philanthropy, business interests, estate plans
and use of capital. He combines the independence and personal accountability of an individual
trustee with the professional infrastructure of an established family office.

Previously, he worked in real estate investment and growing family-owned businesses. He holds
the Certified Financial Planner™ certification, the Chartered Financial Consultant® designation,
the ACCREDITED ESTATE PLANNER® designation and is a licensed Professional Fiduciary
through the California Professional Fiduciaries Bureau.

Kiah earned degrees in economics and business and Spanish at Westmont and completed a
Master of Science in Social Entrepreneurship at USC’s Marshall School of Business. He briefly
taught social entrepreneurship for Westmont’s downtown program.

Committed to strengthening Santa Barbara organizations, he chairs the Santa Barbara Rescue
Mission Board and serves on the boards of the Towbes Foundation, the Santa Barbara
Foundation and Leading from Within. He also belongs to organizations supporting excellence in
estate planning and fiduciary practice. In 2015, the Pacific Coast Business Times named him
one of 40 Under 40. Kiah enjoys outdoor adventures with his wife and four children and plays in
a local soccer league.

Sarah first studied climate change in a chemistry class at Westmont. Today she pursues
passions she developed in college, working for the Crux Alliance, which supports the rapid
implementation of ambitious, cutting-edge climate policies. She shares successes in climate
policy with global audiences and develops strategic communications. Her previous positions
included deputy director of communications for Energy Innovation, a clean-energy and climate
policy think tank in San Francisco, and associate director for advocacy and communications at
Health Care Without Harm, a global campaign to help healthcare institutions and professionals
lead on climate solutions and community resilience.

She also writes about climate justice and policy for publications such as Forbes, Yale Climate
Connections and Stanford Social Innovation Review. Her work involves planning and
implementing successful campaigns, developing strategy, building coalitions and creating
advocacy education and training materials.

In 2015, while she was working in Washington, D.C., at a Catholic social justice lobby, Pope
Francis issued his encyclical Laudato Si’. This document inspired her to pursue climate
solutions, convincing her that addressing the climate crisis promotes justice.

Sarah’s faith animates her commitment to clean energy and climate policy. She serves as board
secretary of Interfaith Power & Light (IPL), an organization that mobilizes people of faith to
support a thriving natural world, helping churches and religious congregations be good stewards
of the Earth.

A political science major, Sarah participated in the Westmont Urban Program and interned with
the International Rescue Committee, which led to her first job helping resettle refugees with the
IRC in San Francisco. She then earned both a master’s degree and a doctorate in political
science from the University of Notre Dame. She lives in San Rafael, California, with her
husband, daughter and two rescue dogs.

The Greeners have served as missionaries with Water for Life (a branch of Youth with a
Mission) for the past 20 years. In 2009, they moved to Rwanda with their children, Christian and
Ava, to direct projects in a dozen African countries, providing clean drinking water to more than
100,000 people. They focus on working with local ministries to help provide water for those in
need and lift up the churches and ministries serving those communities.

Nick and Jen met in Washington, D.C., in 1998 through mutual Westmont connections. With a
degree in communication studies, Jen served as a U.S. Senate staffer while Nick worked in
health policy at the White House after finishing a Master of Public Administration at USC. They
celebrated 25 years of marriage in September 2025.

Current projects have expanded to include partnerships with local churches to build community
farms, especially in Zimbabwe. They provide access to clean drinking water, irrigation for the
farms and opportunities for training in sustainable agriculture and discipleship among the
families through local churches.

The Greeners now operate out of Cape Town, South Africa. Life continues to be an adventure,
and they express gratitude for their years at Westmont that helped provide much of the
foundation for their work and ministry.

Aaron earned both a medical degree and a doctorate in immunology through the Medical
Scientist Training Program at Stanford. His doctoral research applied single-cell multi-omics
technology to human viral infections. During the COVID-19 pandemic, he developed the first
single-cell atlas of the peripheral immune response to severe COVID-19, one of the most highly
used public resources in COVID-19 immunology. 

A physician-scientist, clinical pathologist and translational immunologist at Stanford University
School of Medicine, Aaron is a fellow in hematopathology and serves as the inaugural director
of the Translational Laboratory for Immunology and Cellular Function, which he co-founded.
This new initiative develops novel clinical diagnostics of the immune system to guide more
precise use of immunomodulators and cellular therapies. 

His work focuses on developing next-generation immune diagnostics, single-cell genomics and
translational approaches to immune-mediated disease, specializing in diagnosing leukemia,
lymphoma and other immune system disorders. Aaron has created multiple novel diagnostic
tests for immune system cancers, becoming a recognized leader in diagnosing natural killer cell
cancers and contributing to new diagnostic criteria for these entities.

He majored in biology, chemistry and music and graduated summa cum laude. A pianist with
the Westmont Orchestra, he twice won the Music Department’s Concerto Competition and
founded Sanare Music to bring music into memory-care facilities. He received Stanford’s
Graduate Prize in Music and continues to perform chamber music and collaborate with scientific
and artistic disciplines, passionate about integrating scientific innovation, clinical medicine,
mentorship and the arts to promote human health.
