Jill Calvert


Miss Jill is a graduate of Illinois State University.  She graduated with a degree in math education and began working at Lake Zurich High School after graduation.  Shortly after getting married her husband was transferred to Denver, CO where she began teaching middle school math.  After the birth of her son, Zach, she and her husband moved back to Illinois and settled in Grayslake.  Two years later their daughter, Cory, was born.

Miss Jill stayed home with her children until they were in school full time.  She was then lucky enough to begin working at PLP in 2005. After having taught at both the high school and middle school levels Miss Jill has found the perfect place to be- with preschoolers J.  They have such joy and enthusiasm for life!

Zach currently lives and works in Bloomington-Normal while Cory is beginning her career in Chicago in Occupational Therapy.  Miss Jill loves to spend time with her family- playing games and watching movies, and with her animals.  She currently has 3 cats and 1 dog (but you never know who may join us next).
