Academic Background
Graduated with a B.A. in Mathematics from California State University of San Bernardino in 2002 (in 3 years thanks to starting as a sophomore because of the AP credit earned at Damien). Earned my California Single Subject Teaching Credential in Mathematics from CSUSB in 2004.  Starting working on my Masters of Arts in Teaching Mathematics in 2004. (Hopefully I’ll finish one day although I probably will begin studying some new instead soon)
I graduated from Damien in 1999 following in the footsteps of my oldest brother Aaron (Class of 1990), my uncle Paul (Class of 1969) and my father Anton (1963).  I started in the regular college prep classes and worked hard to get into the honors and AP tracks of school. I passed (earning 3 or better) 7 out of 9 AP exams (Passing: US History, Biology, Psychology, English 11, English 12, Calculus BC and AB (sub score), Statistics,  Didn't Pass (scored 2's) European History and Physics).  I graduated with a 4.23 GPA (ranked 14th in my class of 267).  I played soccer all four years at Damien, was a Kairos leader, and was one of the original members of the Christian Leadership class on campus.    
I attended Sacred Heart School in Rancho Cucamonga from K-8th (It was known as Anton Martin Slomsek or AMS when I first started).   
Outside the Classroom
Coached Soccer at Damien for 4 years
Dean of the House of Eustaquio for 5 years
Mathematics- I truly love math!  I enjoy learning new concepts and applications in the various fields of mathematics.  My favorite field in mathematics is Number Theory followed by Euclidean Geometry
International Travel (Life-long goals is to teach abroad for a year and retire to be a travel guide internationally).
