Debbie Harper - High School Interventionist

Debbie Harper

My name is Debbie Harper.  I am the high school Behavioral Interventionist.  I have worked at Roadrunner School for twenty years.  The reason I have stayed here for so long, is because of the exceptional people I work with.  I consider myself lucky to be among such an amazing group of dedicated and caring individuals.  

I am married to a wonderful man, and have a loving, but rambunctious Pitbull dog.  In my leisure time I enjoy being in the pool and listening to music. I also really like cooking and hosting parties for my family and friends.

Phil Simms - High School History/PE Teacher

Phil Simms

I graduated from Arizona State University May 1978 with a BAE in Physical Education.  I started teaching that same year at Devereux Day School, a private school, in Scottsdale, AZ.    I began my masters program at Chapman University after teaching ~10 years at Devereux. The emphasis of my masters was in curriculum Instruction; however, in the process of earning my MA degree, I took extra coursework to become certified in elementary education and special education.  I earned my masters degree in the fall of 1993 after being employed by Paradise Valley Unified School District.

I was hired to teach social studies to Jr. and Sr. High students, as well as, PE (k-12) at Roadrunner (1992).   When No Child Left Behind was implemented in 2001 teachers teaching in secondary classes needed to be highly qualified in their subject area.   In 2001 I began taking a series of history courses to meet this requirement.

I continue to celebrate daily with my students as they grow and achieve and transition into post-secondary training/education or the world of work.  I am blessed to be able to teach every student at Roadrunner in subjects I feel most passionate about: American Government, Economics and Physical Education (K-12).

I have been at Roadrunner since 2013 and my favorite part of teaching here is getting to know our incredible students! I am excited every day to work toward teaching them how to be lifelong learners and successful citizens who change our community for the better!

Before coming to RR, I taught in the PVUSD Home Instruction program and prior to that, I was a band director for 20 years. I have a bachelors degree in Elementary Education K-8, Music Education K-12, and a masters degree in Special Education K-12.

When I was in high school, my favorite subjects in school were English and band. I am a trumpet player and like almost every genre of music. I have played in bands that have taken me to 11 countries, I also played at Carnegie Hall in NYC. I like almost every sport. I played girl's football in high school and like watching professional football. I played women's softball for many years, but I don't like watching it.

When I am not teaching, I like to spend time with my family. My older son is a chef and we enjoy eating at fun restaurants. My younger son is a professional trumpet player and we like going to rock and jazz concerts. I like to play with my two dogs, Chloe and Lola. Chloe is a sweet Pit bull and Lola is a deaf and blind Great Dane, together they are two handfuls of energetic fun!

I’ve been at Roadrunner for 15 years. Our students are the reason I come to work everyday, they always amaze me. When I was a child, I wanted to be a mom, an artist, and a nurse. My favorite subjects in school were science, art, and theater arts (set design and construction). My working career started in the medical field, I was a nursing assistant in labor and delivery, nursery and pediatrics. Later, I worked at the AZ Motor Vehicle Department.

I love Staffordshire terriers; mine is black and white.

Before coming to Roadrunner I helped students with Reading and math. I believe that every child should be valued and treated with respect. An education should empower a child and help him or her make a positive contribution to our world. I believe that every student comes to school with their own set of knowledge and skills, my goal as a teacher is to meet them where they are and help them be successful.

I moved to Arizona in 2001 after too many cold winters in Wisconsin. While in Wisconsin I worked in the technology department for a large accounting firm. I have been married to my husband Mark since 2005 and we have an eight-year-old son Sam. We also have a crazy one-year-old Golden Doodle named Charlie. Since a very young age, I knew I wanted to become a teacher, after our son Sam was born I decided that I wanted to return to school for my teaching certificate. It has been the best decision in my life.

In my free time I enjoy spending time with our son Sam, reading, biking, hiking, and going to the movies with my friends. One thing I will never turn down is chocolate.

I have a BA in Special Education from Western Governors University. This will be my second year at Roadrunner.

The 2016-17 school year will be my fourth year at Roadrunner. I have a Bachelor of Arts in Elementary Education, ASU 2004; a Master's Degree in Special Education, ASU 2012; and I’m Highly Qualified in Cross Categorical Special Education, High School English. What I like the most about working at Roadrunner is interacting with the kids. Because of the smaller size of our campus, I really enjoy getting to know all the students very well. Every day is a different adventure and it has been a dream come true to come back and teach in the district I graduated from.

My favorite subjects in school have always been Language Arts and English. When I was young, I wanted to play point guard on the Phoenix Suns. Basketball is my favorite sport and I'm still a huge Phoenix Suns fan. I also root for the Cardinals. I have a pit bull mix named Maggie and a cat named Millie. On my free time, I enjoy playing guitar, being outdoors, and walking my dog. I love reading, and I am a big Stephen King fan.

I’m originally from the Oregon Coast, but have lived in Washington (state), New York City, and Alaska. I am a veteran of the Army National Guard, in which capacity I was deployed to New Orleans to help out with the relief effort after Hurricane Katrina. I also spent a year in Afghanistan. I’ve been in Phoenix for about eight years and lived in the PVUSD for the last four.

I have a Bachelor’s of Science degree in Natural Resources Policy from Oregon State University, and completed the Post-Bacc Teaching Certificate-Secondary Education program at Rio Salado College--I did my student teaching at Shea Middle School, and worked as a substitute teacher in the district. This is my first year at Roadrunner.

My teaching specialty is science--I believe that promoting science literacy among the next generation is going to be critical in solving the challenges that lay ahead for our human society and the health of the planet--but I’m very excited to be working with Mr. Ratliff in the Roadrunner English classroom. I’m a novelist, and have authored, co-authored or ghostwritten more than thirty novels, as well as several magazine articles, but I’ve always felt the need to make a meaningful contribution to the community, and helping educate the next generation seems like a great way to do that.
