Mr. Tony Scott, Principal & 8th Grade Administrator

​​noid1y11056.jpg​I was born in Kansas, but at an early age moved to Lincoln Nebraska. I am the third child in a family of four children. Having attended the University of Nebraska, I still have strong ties to the "Big Red" athletic programs and continue to be a fan. I moved to Colorado Springs in 1985, having a love of the mountains, hiking and camping. I taught and coached at Air Academy High School before moving to Liberty High School as a teacher and coach. I had the opportunity to wear many hats while at Liberty as I performed the duties of Dean of Students, Athletic Director and Assistant Principal. I've been a Principal in the district since 2001 at Mountain Ridge Middle School and Challenger Middle School.

My wife is a school counselor and I have a son and two daughters. I love to be outdoors and enjoy those pursuits that brought me to Colorado in the first place.

Every child has gifts!

They each unwrap those gifts at different times throughout their lives. It's the responsibility of teachers and administrators, in partnership with parents, to help each child find their gifts. Children must have a solid academic core foundation as well as exposure to a variety of co-curricular and exploratory activities to help them explore their areas of interest. Educators need to develop positive relationships with students and work to remove obstacles so that each child can grow to reach their full potential and utilize those their own unique gifts.​

Personal Biography: I am a fourth generation Colorado Springs native (my two boys are fifth generation natives). I graduated from Doherty High School in 1985. I married my husband, Brad, in 1995. Our son, Bennett, was born in 1999 and Samuel was born in 2002.

Professional History and Credentials: I have a BS from Colorado State University and a BA from the University of Northern Colorado. I received my Masters degree in Education Administration and Supervision from the University of Phoenix. My 1st teaching job was as an English teacher at Liberty High School. After being in the classroom for four years, I took a position as an at-risk, drop out prevention coordinator at Liberty. I then became one of Liberty's assistant principals. I became an assistant principal at Challenger in 2002.

Philosophy about teaching /administration: I believe that one person can change a child's life. I have a particular passion for working with at-risk students. I view my role as an administrator as one of guidance and teaching, as well as helping students become responsible citizens.

I love my job here at Challenger an am very proud of our students and staff.

 Mrs. Liz Alvarez, Assistant Principal & 7th Grade Administrator

noid1y11222.jpgPersonal Biography: I was born in Miami, Florida, but have lived in the Springs since 1993. My husband, Juan, and I were married in 1986 and have two children.  My daughter, Jessica, was born in 1990 and my son, Anthony, in 1992.  Both attended District Twenty from kindergarten thru 12th grade, graduating from Rampart High School. Jess is a UCCS graduate and Tony attended there, as well. 


Professional History and Credentials: I purposely chose the University of Florida because they had a middle school program.  I was determined to be a middle school teacher because I felt that was the most influential time in my life.  I earned my bachelor's and master's degrees there shortly before moving to Colorado.  My administrator license was earned in 2007 through the University of Phoenix. My 25+ years in education have mostly been at the middle level teaching math and Language Arts.  Timberview was my first D20 home and then I opened Mountain Ridge in '97. I am thrilled to be a cheetah and look forward to continuing my years with D20 here at Challenger. 


Philosophy: All students CAN learn.  We need to take them from where they are and help them to grow academically and emotionally.  Every student needs someone who will take an interest in them and help them grow as a person. My role is to provide guidance and to serve as a positive role model in their lives.
