This year will be my “trifecta” – third year in Third Grade at STS and my fourth year overall. I look forward to working alongside Mrs. Toussaint, again, this year. Third Grade is an exciting year filled with new routines, challenging work, standardized testing, exciting Field Trips, Team building skills, and, of course, a bit of fun!

For those of you that I haven’t met…I live in Crystal Lake with my husband, Mike, who does fundraising for the local sports teams. My daughter, Meaghan, just graduated from St Mary’s University in Minnesota and will be completing a Service Year in Psychology, in Denver, CO this year. My son, Jack, will be continuing his education at Western Kentucky University as a sophomore this year.

After college I taught for 9 years in private school education, and then stayed home to raise my children. I, then, taught for 3 years in District 47 and came full circle 3 years ago, back to private education, in First Grade, here at STS. The atmosphere of a Catholic school is what pulled me back.

I look forward to Third Grade, again, this year and am happy to be a part of the STS family. This is my home parish and I feel truly blessed to work with the amazing staff and wonderful families here at St Thomas School.

I am very excited to be teaching 3rd grade this year! I really love teaching here at St. Thomas! I have been working with children all of my life. I have directed summer camps for children up to 10 years old, I was involved in the Confirmation program at St. Mary’s in Huntley, I taught 4th grade CCD for ten years and I have directed and taught in many different preschool programs. I hold a BA in Social Science with an emphasis in Psychology and a minor in Physical Education. I also hold a post bachelor teaching certificate to teach K-9 in the State of Illinois.

 I have always been passionate about my faith and am very happy to be working with so many wonderful people who share my values. I treasure the opportunity to teach children about Jesus during my work day. I have lived in Crystal Lake for five years with my husband and love it here!
