• Greetings, RES Families.  

    Due to the circumstances regarding COVID19, our campus and district are closed.  Myself and the RES staff are readily available for you while we are working from home.  I am available on campus on limited days, but email and phone is the best way to contact me.  

    To our students, I really miss you. Our school is not the same without you here!  I am looking forward to when things can be back to normal.  Until then, please keep reading and practicing with school work that has been provided to you.  Enjoy the time with your family and remember to spend some time reading everyday!

Mrs. Jennifer Foster

I am honored to be the Principal of Roger E. Sides Elementary. My experience ranges from a classroom teacher (K, 2nd and 5th) to an intervention teacher. I also served as the Assistant Principal of R.E.S. Elementary for 2 years before becoming the Principal at KC Primary.  I have made my way back to RES, the place where my career in education began.  

I am a 2008 graduate of University of Houston - Victoria and a 2011 graduate of Texas A&M University - San Antonio.

I stayed involved within our community through volunteer work and by being a part of several community organizations.

I hold an open door policy for staff, community members and parents of Roger E. Sides Elementary.  

My immediate family consists of my husband, son and two dogs.

Please do not hesitate to contact me if you have any questions or concerns.
