David Chong, Governance Chair

Previously, David owned and operated The Park at Mount Helix and founded an Internet-based senior housing referral service, AssistMatch. Early in his career, he practiced corporate law in Taipei at Jones Day and later served as a Business Advisor at the microfinance nonprofit, ACCION San Diego. As a foundation to his career, David’s most useful degrees are his B.S. in Business Administration from Biola University and his J.D. from Boalt Hall School of Law at U.C. Berkeley. The not-quite-as-practical program was the M.A. in Practical Theology from University of San Diego. At various times he has held licenses in California as an attorney with the State Bar, as a broker with the Department of Real Estate, and as a Residential Care Facility for the Elderly Administrator with the Department of Social Services.

Sandra Nimitz Lawhon
Sandra Nimitz Lawhon exemplifies the perfect lifelong learner. While her life journey has been full of twists, turns and challenges, Sandra always found comfort in learning something new and conquering a new intellectual challenge. Born in Philadelphia, only daughter of a naval officer and an accomplished pianist and singer, Sandra always excelled in school. After losing her father to cancer and witnessing her talented mother become a controller in a major company in the 1950s, one of very few women in an executive position, Sandra graduated high school at 16 and studied English Tudor History, education and architectural design. She continued her studies eventually getting a PhD and teaching both elementary school and history at the college level. While encouraged and mentored, Sandra has always been a proud earner of her way through life. Sandra purchased her first 4-unit property in San Diego with her mother and has not stopped since. Never afraid of the next challenge, she has obtained contracting, lending and banking licenses. She is excited to join the San Diego Oasis board because she believes she can truly make a difference. Sandra feels that seniors are the most underserved population group and can become the most expensive segment of society, if not treated well and fully engaged. A generous current and legacy donor, Sandra is hoping to find time to carve out more time for fun – brush up on French, learn piano, and enjoy more theatre and travel. Her community service includes YMCA, YWCA, San Diego Opera, and Serving Seniors.
