Professional Biography

I earned an A.A. degree in Business Administration in 1985. Throughout my high school days, I worked in the Superintendent’s Office and the High School office. I moved to California in 1987 and became a buyer for General Electric Aircraft Engines. In 1990, I transitioned into Human Resources as a Human Relations Specialist. I worked in HR until 2001 when we were blessed with a daughter, at which time we decided that I stay home to be with her. As of August 2011, I began working as a part-time Health Clerk at Ontario Christian Elementary school.

Personal Biography

I am a Colorado native and lived in Denver for nearly 22 years. I have been married to Kevin since 1987. We have two children, Aubrey and Peyton. Both have been at Ontario Christian School since preschool.

Philosophical Biography

I believe a balanced life consists of Christ being centered in family, church, and school. Christian education is so important and I feel so blessed that my children are able to attend this school. It is a privilege and a blessing to be able to work in such an environment where I come in contact with so many wonderful OC families, on a daily basis, who gives me joy and strength. The precious children are a reminder that Christ loves every little child, and they bring such joy to this office. One of my favorite verses from Psalm 5:11 “But let all those that put their trust in You rejoice: let them ever shout for joy, because You defend them: let them also that love Your Name be joyful in You.”
