Here's to Success!

Here are some helpful hints for students and parents towards virtual success this year:

  • Complete, CORRECT, and submit every assignment (show your work) on time.
  • Ask questions.
  • Access resources (in class, textbook, School Loop, Google Classroom, Pearson Realize, etc.).
  • Copy the notes and the problems I do with the class (writing them reinforces them in your brain).
  • Ask questions.
  • Study for tests.
  • Ask questions and get help as needed.
  • Take make-up tests when necessary.
  • Participate fully every day.
  • Be respectful of everyone in word and deed. (Be positive and keep your language clean.)
  • Keep your phone put away during class (and ears free of AirPods and earbuds).
  • Check those online grades often.
  • Complete any and all make-up work promptly.
  • ASK QUESTIONS. (Do you notice a theme here? 😉)

Welcome Back to Math!

This is my 21st year at Alhambra and 36th year of teaching. Yes, if any parents were born after September, 1985, I have been teaching longer than they have been alive. I may be getting old. ;) I have taught everything from third grade and fourth grade to elementary P.E., to middle school math and P.E., to high school P.E. and math through geometry. I've coached football and tennis.


My wife and I have been married for 34 years. We have two grown sons, a grown daughter, and a daughter-in-law. My hobbies include skiing, swimming, hiking, music, cooking, art, and following the 49ers, Giants, and Warriors.


My aim this year is to take my students forward on the mathematics highway to graduation and beyond. Did you catch the reference to Toy Story? Warning: Dad jokes ahead! Although I'd rather be outdoors, I do love math as well. Welcome to my class. Let's have a great year!

Submit assignments via Google Classroom. Use Pearson Realize in the "waffle" for access to the textbook and Aeries for grades. Email me with questions, or ask me in class or during Office Hours.
