It is a great privilege and honor that the communities La Verne and San Dimas have shown their trust in me to serve as a Governing Board Member for the Bonita Unified School District for 17 years.  My family and I have lived in San Dimas since 1987, and both my children are proud graduates of Bonita Unified.
I retired from the Los Angeles Fire Department in 2016 after 35 years serving the communities of downtown Los Angeles, East Los Angeles, and South Central Los Angeles primarily.
My involvement with Bonita Unified began when my son entered kindergarten. Before being elected to the Board of Education, I served as a classroom parent volunteer, school site council member, and school site chairperson. I also became the first male Bonita PTA Council president in BUSD history - a position I held for three terms.
One principle that has guided me from the very beginning, and I still rely on when making every decision, "Is this the best possible choice for our children?" I believe every decision our District makes must be made with this premise in mind and to account for the interests of our other stakeholders, such as employees, parents, and the citizens of our communities.
Bonita Unified is a great district with wonderful students, outstanding staff, and involved parents. Together, we can make it even better.

Chuck and his wife Janette have lived in the district since 1992, and their daughter graduated from San Dimas High School.  Chuck's activism and involvement with the school district began when his daughter was attending Gladstone Elementary School.

Serving as a member, and then as chairman of the School Site Council, he helped the group provide guidance and support to the school, working with school staff and management to implement innovative programs.  He was also active in the Gladstone PTA as Vice President-Ways and Means, and was selected as the Bonita District PTA Parliamentarian.

Before becoming a teacher, Derek worked in a variety of jobs, including a mover at Mayflower, Youth Director at WCCC, an AOD supervisor at the Trinity El Monte campus, a general manager at a Subway restaurant, and a substitute teacher. Derek's top priority is seeing Bonita USD provide students with a rigorous and well-rounded education in an encouraging environment. This includes expanding the trade education pathways.

He has also been a nonvoting union representative on a health benefits committee.
