Ms. Carol Lilla
Hello and welcome to my website.  I am really excited to be starting my sixth year at Tri-City United.  This is my  44th year of teaching.  I started my career at Holy Redeemer School in Montgomery.  I taught Math and Physical education and also coached the junior high girls sports.  In 1981, I was hired to teach Math at Montgomery-Lonsdale High School and coach volleyball and basketball.  Previously I have  been varsity coach of softball, volleyball and girls basketball at MLHS and softball at TCU.

I obtained my teaching degree at Winona State College with a major in math and a minor in sociology.  Later, I obtain a coaching certificate from  Minnesota State Mankato and a Master's Degree in Education from St. Catherines University.

This year along with Computer Science, I will be teaching Algebra 2B and Geometry A.  We will be using the educational tool Moodle and the class will be run using the flipped technique.
