Parker County's only training facility for gymnasts to reach their Olympic dreams! Tina Rusinovich, the owner, first opened the door of The Rock in November 2007. As a Christian business woman, she is proud to claim the Lord and Christian morals in her business practices and all programs offered at The Rock. Our scripture verse proclaimed on the wall as you walk in is "The LORD is my rock, my fortress and my deliverer; my God is my rock, in whom I take refuge. Psalms 18:2. We hope you and your child feel welcomed during your time with us.
