Dear Cheetah Parents and Families:

Welcome back to another new year of learning, growth and fun!  We hope that you and your child(ren) enjoyed a restful, safe and fun summer.  We're so excited to work with you again, to help your child's school experience feel positive, warm and caring.  I want to thank you for supporting your child(ren), we will persevere and work hard together through whatever challenges come our way.  

As we start a full-time, in-person school year,  I encourage you to stay connected with our teachers and support staff, so that we can help your students succeed.  This is one of the best ways to stay updated on your child's academic and social progress at school.  In addition, I'd like to introduce our newest School Counselor Rebekah Sieg.  You can learn more about her below! 

If you're seeking social emotional support, guidance or to chat about any questions or concerns you have - Rebekah and I are here for you!  Together, we can explore solutions that can help your child's continuing growth at Challenger. Your child's social, emotional and mental well-being are a top priority for us. Below are some ways you and your child can connect with us.  Please reach out in whatever way works best for you. I look forward to working with you!
