Cory Yates | Co-Owner
Cory Yates has spent 29 years in the restaurant industry, in one form or another. Historically an entrepreneur, Cory has built and sold five businesses over that time, only to start anew with an increased excitement and vigor.
Most note-worthy, previous business endeavors include Accurate Chemical, sold in 2004, now a thriving juggernaut serving the restaurant industry throughout the southwest and Remington Restaurant Equipment Repair, sold in 2012. Lucrative in that industry approach, the current business venture is Alpha & Omega Restaurant Equipment Repair founded in 2015. Yates and co-owner and Edgar Martinez, lead technician for Alpha & Omega, seek to fill the gap between the larger, but less responsive companies and the unlicensed, uninsured “fix-it-all” guy.
The theory for Cory is to be customer centric. “Bend when you need to and give back to those who trust you with their own livelihood. Build relationships based on that trust and typically, all the results take care of themselves”.
Steady growth and a solid reputation for an unparalleled customer experience, industry revered skills, teamwork and accurate communication are, and always will be, Alpha & Omega’s goals. While other companies strive to be the largest in Arizona, Alpha & Omega Restaurant Equipment Repair strives to remain the very best.

From the moment I met the Administrative Team for my interview, I knew this was a company I wanted to be a part of. Their family bond and contagious enthusiasm for the company’s future, is unlike anything I’ve ever experienced.
