Greg Frederick started his career in education at Tulsa Public School’s East Central High School where he taught Social Studies and coached football and track.  Greg has been in school administration since 2009 and has served as a Dean of Students and District-level Coordinator with Tulsa Public Schools and as an Assistant Principal for Union Public Schools at the 6th/7th Grade Center. In 2013 He was hired as the Principal of Jefferson Middle School in Oklahoma City Public Schools, and in 2015 began serving as Principal for U.S. Grant High School, Oklahoma City Public School’s largest high school.  At U.S. Grant, Mr. Frederick oversaw exponential growth in both the schools’ student population and the schools’ programming; creating or piloting many school based programs to help students overcome obstacles in their educational careers. In 2020, Greg was named as OKCPS’s Outstanding Principal of the year by the Foundation for OKC Schools. 

“Mr. Frederick’s experience is impressive, and we feel it has prepared him to be a great leader for the Mustang Education Center,” Executive Director of Human Resources, Chris Tobler said.  Assistant Superintendent of Secondary Education, Ryan Mckinney added, “Greg has a very successful track record, and we feel like he will be a great fit to lead at the MEC.”  Superintendent Charles Bradley concluded by adding that “We are excited to see the great things that he will do in his new role.” 

“Words cannot begin to describe how excited I am to join the MEC Team,” Frederick said.  “I have always seen it as my responsibility as an educator to give students opportunities for growth and to take away obstacles to learning.  I can think of no place more suited to do just that than Mustang’s MEC. To give our district’s youngest students the opportunity for the best possible start in Pre-K and to remove obstacles to graduation for our students in Alternative Education, it’s the best of both worlds. I am looking forward to serving my home district and community and I’m very excited to be a Mustang Bronco!” 

Greg and his wife, Courtney, have lived in Mustang for almost ten years.  Courtney is a Mustang Alum and has previously served in the district as a Student Support Specialist and classroom Para at Trails Elementary and Counselor at Prairie View Elementary.  They have two children in Mustang Schools, Phoenix (9) and Conley (6) both of whom attend Trails.

Hi, my name is Michael Mattingly.

I'm the Custodial Supervisor at MEC.  I retired from a major Airline in October 2008 and started the next chapter at MEC in August of 2009.

I value our students and staff members everyday as I meet and greet them with a caring smile. My team and I do a quantitative analysis of the school site to ensure the students and staff enjoy a sanitary and secure environment for learning activities.

As for me I always love a good hike at a State or local park and kayaking. I have a lovely wife who is a teacher at the Mustang High School, a lovely daughter and a beautiful fur baby named Macy.
