I am honored to serve on the Governing Board of the Bonita Unified School District and with the trust you have shown in me. My family and I have lived in San Dimas since 1987 and both my children currently attend District schools.

I am a retired Captain for the Los Angeles Fire Department with over 25 years of service and currently stationed in East Los Angeles.

I began my involvement with BUSD when my son entered kindergarten serving as a classroom volunteer, school site council member and the first male PTA President in Bonita Council history, serving three terms.

One principle has guided me from the very beginning, and still applies today. "Is this decision the best possible choice for our children."
Every decision our District makes must be made with this premise in mind and also account for the interests of our other stakeholders, such as our employees, parents and the citizens of our communities. We owe it to our children to provide them with the best educational opportunities possible.

We have a great District with wonderful students, outstanding staff and involved parents. Together we can make it even better.
