I have been teaching at ERHS Magnet since September 1994. I attended public school in Los Angeles starting with Castelar Elementary School, then Mount Gleason Junior High School, and Verdugo Hills High School which are part of LAUSD. I obtained my BS in Mathematics from Cal Poly Pomona and my MS in Mathematics, Teaching Credential, and CLAD from Cal State LA. Other than English, I can speak Cantonese, Mandarin, Chiu Chow, and Cambodian. I have also been teaching at Pasadena City College as an Adjunct Assistant Professor for their math department since January 2002.
