Our Story

At its core, Riley Engineering was founded to improve the lives of people by ensuring that all have the necessary civil infrastructure to facilitate socioeconomic well-being. The company was founded by Dr. Ronson Riley Chee, Ph.D., P.E., who is from the community of Leupp, Arizona on the Navajo Nation. Having grown up on the Navajo Nation where socioeconomic hardships stem largely in part by the lack of basic potable water infrastructure, motived Dr. Chee to pursue the field of civil engineering and founded a civil engineering company with a specific mission to improve the quality of life. Founded in 2017, the company was named in honor of his maternal grandfather, Riley Jones, and nephew, Riley Honani to carry on a legacy of excellence, integrity, service, compassion and hard work. 

Our Mission

Ensure people and communities throughout the world have the necessary civil and water infrastructure to thrive and facilitate economic wellbeing. This is accomplished by upholding integrity, striving for excellence in all that we do, and recruiting passionate engineers. We promote high technical competency in our workforce and solve complex problems through innovative and state of the art engineering methods. 

Our Vision

A world where communities have the necessary civil and water infrastructure to sustain life, ensure socio-economic well-being, and economies are vibrant and thriving. 

Our Core Values


We do the right and honest thing no matter the price. We hold ourselves to a higher standard 

“The integrity of the upright guides them, but the unfaithful are destroyed by their duplicity” (Proverbs 11:3) 


We strive to do the best job we can regardless of the size of the project or task at hand. Mediocrity does not cut it at Riley. 

“Whatever you do, work at it with all your heart, as working for the Lord, not for human masters, …” (Colossians 3:23)


Engineering is our passion. We seek to find team members whose talents and giftings align with their passion for the engineering profession and helping others. Our founder has a passion and calling for engineering and thus we only seek likeminded team members. Our engineers at Riley love what they do, this translates into higher energy, higher performance, more creativity and high-quality work products. 

“Each of you should use whatever gift you have received to serve others, as faithful stewards of God’s grace in its various forms.” (1 Peter 4:10)

We Listen

As a client we know that you understand your needs better than anyone else. We do our best to listen and fully understand the problem first, then determine how we may be of assistance. We don’t engage in a project unless we are confident, we are the right team to help.

We Find the Answer

We may not know all the answers, but we will find it. Research is at the core of what we do. We know how to research, and we know how to solve problems. The founder of Riley has a Ph.D. in Civil Engineering and thus, thoroughly understanding the problem and researching solutions are integral to our training and embedded in our design process.

Our Work Ethic

We carry on the teachings of our elders of good old fashion hard work. No lazy people here. We know how to deliver and do what it takes to get the job done. We set the bar high for our team and staff.
