About Our Board

Kevin YenKevin Yen, President

Kevin has enthusiastically supported the Foundation since its inception in 2005, working with the Armstrong family, the Santa Ana Unified School District (SAUSD), and friends to continue Dr. Armstrong’s service to the student-athletes of Santa Ana.

At Woodbridge High School, Kevin became lifelong friends with Dr. Armstrong and fellow board member Kevin Tonai. Between games of Intellivision, track practices and late night “study sessions,” Kevin witnessed Dr. Armstrong’s dedication to achieving his goals and his service to others in the community. By working at the Foundation, Kevin continues Dr. Armstrong’s legacy of community service and belief that all kids deserve the opportunity to realize their full potential. Kevin applies his business experience to oversee the Foundation’s finances.

After living for a number of years on the East Coast, Kevin is happy to be back home in Southern California, where he can surf year-round and only see snow when he and his wife go to Mammoth. Kevin can often be found at a 5k race cheering for the kids and occasionally trying to keep up with them.

Kevin has an MBA from Dartmouth College and undergraduate degrees in economics and computer science from UC Irvine.
