Welcome students and parents.  This site is designed for students currently in my math classes as well as their parents and guardians.  I am currently teaching Geometry and Advanced Geometry.  This is my 9th year teaching at CDO and I absolutely love the students and faculty.  I graduated from CDO in 1980 and it is great to be back in "Dorado Land". 

 Core Educational Belief

I believe that all students can learn and be life-long learners.  Therefore, I strive to provide diverse educational opportunities that encourage my students to become innovative and knowledgeable about mathematics in order to pursue future endeavors.
