Principal Janet Blackwell grew up in the small town of Pleasanton, thirty miles south of San Antonio. She attended Pleasanton High School where she displayed athletic prowess in several sports. She received a B.A. in Education from Southwestern Assemblies of God University in 1990; the same year she married her husband, Dawain Blackwell. She has taught 2nd, 3rd, 4th, as well as Gifted & Talented and Special Education. She received her M.S. in Educational Administration from Concordia University Texas. 


Her desire is to guide students to look at their life like a race. They must run their own race, meaning that they should not compare themselves to others but instead embrace their unique talents and abilities. If they are distracted by how others are running, they will not discover the course for their life. 

PURPLE is Ms. Blackwell's favorite color, which denotes good judgment and/or happiness. In her spare time, she and her husband love to train for marathons. She has completed 19 marathons. She finalized her dream by competing in the 2013, 2014, and 2015 Boston Marathon. When she is not running, she also enjoys reading or watching movies curled up with her two dogs: Belle and Foxie.

Mrs. Haily May Christensen comes to Rockenbaugh Elementary School after serving two years as the Assistant Principal shared between Johnson Elementary School and Walnut Grove Elementary School. Prior to that, she was in the Austin area at Blake Manor Elementary School where she served as the Assistant Principal for two years and an instructional coach for one year. 

After graduating from the University of North Texas with a B.S. in Interdisciplinary Studies in 2011, Mrs. Christensen taught at Walnut Grove Elementary School. She then went on to complete her Master’s of Education in Curriculum and Instruction specializing in Educational Leadership in 2013, also from the University of North Texas. She comes with a variety of first-hand elementary school teaching experience. During her career, she has been a 1st grade, 3rd grade, and 5th grade teacher.

Mrs. Christensen and her husband are both Carroll graduates and lifelong Dragons. Living in the Rockenbaugh Elementary school zone, they are looking forward to many wonderful years with the RES community. A little bonus fact about the Christensen family, they recently welcomed their first little Dragon into the world and cannot wait to watch him grow up a Dragon, just like mom and dad!

With a continued commitment to our core values of excellence, relationships, character and integrity, innovation, open and honest communication, and compassionate service, we are pleased to recommend Mrs. Haily May Christensen for Assistant Principal, Rockenbaugh Elementary School.

Mrs. Ashley Aldridge is starting her 13th year in education. She is overjoyed to be in her second year as the counselor at Rockenbaugh. Mrs. Aldridge taught 3rd grade at Walnut Grove Elementary for 9 years and prior to that she spent time in 5th grade, 6th grade and 8th grade classrooms.

 After growing up in Crowley, Texas, Ashley moved to College Station for her college years. She graduated from Texas A&M University in 2010 with a Bachelors in Interdisciplinary Studies and then again in 2016 with a Masters in School Counseling. Needless to say, her family bleeds maroon! Whoop!

 Mrs. Aldridge is not the only counselor in the family, her husband Adam is a middle school counselor in Northwest ISD. Ashley has two little ones of her own that definitely keep her on her toes- Grayson will be 4 in December and Avery will be 2 in January.

 Mrs. Aldridge loves spending time with her babies, traveling, crafting and shopping. She cannot wait to learn and grow with all the amazing kiddos at RES and help them navigate these precious elementary years!
