Mrs. Courtney Biller

Welcome to Hillcrest Math!! I will be starting my 20th year of teaching in Deer Valley School District. I have experience in 3rd-6th and gifted Math. I have been a teacher at Highland Lakes (1.5 years) and Las Brisas (14 years) and so excited to be apart of the Hillcrest staff I will be jumping into my 5th year being a Falcon. 
 
I have 3 wonderful children, a set of identical twin girls going into 9th grade and a son entering 4th grade.
 
I look forward to exploring and investigating the math concepts this year with your child!
