Mrs. Heather Sienkiewich

Welcome Rucker Eagles!

My name is Heather Sienkiewich and I am beyond blessed to be with our Rucker family and 5th grade team this year!  This will be my 2nd year teaching 5th grade and my 8th 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 sweet baby boy Noah.  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 be working with our Prosper families this year!
