What a school year! Marked by a really fun Winter Formal, Posters, and a TikTok spirit day. Those were the days.  I miss everyone so much and I am in sadness I don't get to see you on the last days of school.  I want thank students and parents for being kind, patient, and repectful in this insane time.  Learn from this process. 

Seniors:  I hope you had a rewardning and valuable experience at Canyon Del Oro High School.  I belive it is th best high school in Tucson and it is a priveledge to be able to attend.  It also holds a great reputation so you can go into the world being PROUD to be a DORADO.  I sure am!  Thank you all for the hard work.  I hope your summer is mild in temperature and you get to find the people you are meant to be.  Congratulations class of 2020.

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.
