Mrs. Heather Sienkiewich

Welcome Rucker Eagles!

My name is Heather Sienkiewich and I am beyond blessed to be a part of our Rucker family and 5th grade team!  This will be my 3rd year teaching 5th grade and my 9th year teaching math.  I previously taught 6th grade math and coached athletics.  

I attended Texas State University where I ran cross country and track for the Bobcats and met my amazing husband!  We are proud parents to our energetic Noah and our sweet baby Piper.  We love attending church, playing sports, and going on outdoor adventures together!

I have a passion for math and helping all students reach their highest potential!  I am so excited to partner with your child and family this year!
