I have been a counselor at both San Dimas High School and Lone Hill Middle School. The last 10 years I have been the Assistant Principal of Academic Success at San Dimas High School. I am so proud of the students who attend San Dimas High School.
 
I grew up in Chandler, Arizona and attended Chandler High School. I spent my freshman year of college at Scottsdale Community College, the home of the Artichokes. That is correct, the mascot is an artichoke. I received my bachelor's degree at Azusa Pacific University in Physical Education. Then my master's degree and administrative credential at Azusa Pacific University.
 
I have four kids. Three of my kids graduated from San Dimas High School. My oldest Tyler is a Lineman for the California/Nevada. My daughter, Hannah,  attended the Air Force Academy and is now married in Mississippi. Ben is attending Cal Poly Pomona. My youngest, Jacob is a senior at SDHS.

It is my honor to serve as Assistant Principal at San Dimas High School. San Dimas High School is destined for great things and I am so excited to be a part of it. I look forward to helping students and staff to reach for the great expectations San Dimas High School has established. Getting involved is the best way to reach these expectations in the quick four years of high school. Four years that students remember for a lifetime.

I am excited to serve the students, parents, and staff of San Dimas High School as Assistant Principal. I have previously served as an instructional coach, department chair, and math teacher in the Monrovia Unified School District and Los Angeles Unified School District spanning 13 years. 

I grew up in El Monte and graduated from Arroyo High School. I earned my bachelor’s degree in mathematics and master’s degree in education from UCLA. Go Bruins! I completed my administrative credential at Cal Poly Pomona and am also currently mentoring new students in the Preliminary Administrative Credential Program as a consultant. I love all new and future Bronco graduates! 

My wife, Genevieve, is also a proud educator as an elementary special education teacher. We are raising two beautiful girls, Leanne and Jordan. With the help of two grandmothers, our family does our best to cultivate a trilingual and tricultural household of English, Chinese, and Spanish. We are a family that loves hiking on weekend mornings, enjoying a family movie night with plenty of popcorn, and experimenting with baking sweets.

I absolutely loved, loved, loved my high school experience. I learned to be an avid runner by completing two marathons on the marathon team. I learned to be an active community member through volunteering in Key Club. In addition to excelling in academics, I intend for every San Dimas High student to find their life passions through the many wonderful clubs, sports, and organizations on campus.
