Helen Coffeen,
I just completed my 40th year in the Crane District. I was a teacher at Rancho Viejo for 12 years in 5th, 6th and 3rd grade. I met my husband who was a PE teacher there and all three of my boys attended Rancho Viejo. Then I was an assistant principal for a total of 12 years at Crane Middle, Pueblo and Rancho Viejo. I have been a principal for 16 years 9 at Rancho Viejo and for the last 7 years at Centennial Middle School. I love being a principal and seeing all of my past students grow up and bring their children to my school!

Sonya Green, 
Assistant Principal

As your Assistant Principal, I want to thank you for the opportunity to work with our dedicated staff, our parents, and our students here at Centennial. There will always be challenges ahead of us, but it is essential to recognize that those challenges are there to give us a chance to build character, to learn, and to grow. 

Ever since I was in 5th grade I knew I wanted to be in education. Born and raised here in Yuma, I have been an educator for over 25 years. I am a member of the Arizona Educational Foundation’s Principal Leadership Academy, and formerly a Writing Coordinator. I also served as an Instructional Coach and a Lead Teacher. My teaching experience ranges from elementary level to middle school, and I was a Yuma County Finalist for Teacher of the Year.  

I look forward to working with you as we bridge the gap between home and school. Together, we can ensure that every student has opportunities to excel, while at the same time, helping them build positive relationships that will last a lifetime. With a positive attitude, a growth mindset, and a good character, I believe anyone can achieve great things.
