I was born in California and have lived in Arizona for 25+ years.  I graduated from CDO in 2002.  I went to Northern Arizona University in 2008 and graduated with a Bachelor's of Science Degree in Secondary Mathematics Education.  This is my seventh year as a teacher at CDO as a teacher and I am so excited to continue my career here. 

I make jewelry, bicylcle riding, hiking and traveling in my spare time when I am not grading. 

Over the summer I took a road trip to Utah and Colorado to visit Zion, Rocky  Mountain, and Arches National Parks.  

Mathematical Philosophy

I believe students need a strong foundation in mathematics to be successful in STEM (science, technology, engineering, and math) degrees and careers.  Students need a diverse, enriching, and supportive environment to achieve mathematical understanding and mastery.
