    Welcome! I am very excited to be teaching mathematics at Hamilton High School. This will be my fifth year here not only at Hamilton, but also in the state of Arizona. I am excited to continue growing as teacher and learning from my students.

    My Education and Professional Background

    I graduated from California State University Fullerton with a B.A. in Liberal Studies in 2007 and then continued my studies at Pepperdine University where I earned a M.A. in Education. I taught in Los Angles for 7 years serving the community I grew up in. I am now entering my 12th year of teaching and although I have primarily taught Algebra 1, Geometry and Algebra 2, I have also taught Biology and Anatomy & Physiology.

    My Educational Philosophy

    I believe all students can and will learn.
