Mrs. Tonia Hardtke

HELLO!  ¡Bienvenidos!  I have been a teacher in CCSD #89 since 2001. Currently, I am an "EL" teacher at Glen Crest Middle School.

EL stands for "English Learning". Something I've learned over time is that we are ALL English learners!  

Working with students and families who speak languages other than English is my passion as an educator. Helping students acquire and improve their English language skills while empowering them to succeed in the classroom is my mission.

Education: Bachelor of Science - 1993, Master's in Curriculum & Instruction - 1997, ESL Endorsement - 2008, ESL Bilingual Endorsement - 2015, Middle School Endorsement - 2017. Lifelong learner.
