ABOUT ETHOS

Logo_ETHOS_Hand_Trans.png

Sergio Oliden opened the doors in 2012 and hit the ground running on some large design projects thanks to the incredible communities here in Maricopa County, Arizona. Since then, Sergio's reputation grew not only for his design and construction background but for the way he served his clients. Sergio solidified the foundation for Ethos' people-over-profit culture. Keith Dahlen and Nicolai Oliden joined the company in 2016 with the dream of taking the company to the next level.

We have been extremely blessed by our clients, colleagues, and community for continuing to reach out to us for their design needs. Our company has grown since 2016 and our "people first" culture, servant leadership nature, and commitment to excellence has only strengthened with each new team member we bring on board.

Ethos is a certified DBE/SBE company with services covering structural, roadway, civil, and geotechnical design.

MISSION & VALUES

To foster the well-being and growth of our employees in order to passionately serve the needs of our clients and community.

 
People Matter

We put people – team members, clients, and family – first. Every single person deserves to be treated with respect, dignity, and a caring heart.

Infectious Enthusiasm

We believe we work at the best company in Arizona! That enthusiasm overflows into our design and coordination on every project.

Unyielding Integrity

We hold ourselves to the highest level of integrity. We tell the truth, take responsibility for our mistakes and failures, and we honor our commitments, even when it is difficult, expensive or inconvenient.

Two Ears One Mouth

We seek first to understand any problem that faces us or our clients.

Embrace and Drive Change 

We understand we live in a constantly evolving world. We aspire to embrace new technologies and methods and present opportunities to our clients to improve their projects.

Make it Better

We are human which means nothing is perfect. We constantly work to make things better – design better, lead better, serve better. Whatever it is, we seek to continually improve to better serve our team and clients.

Teamwork Makes the Dream Work

We work as team members and not employees. We aspire to be the best team players and work closely together with
our clients to bring success to their projects.

Excellence in the Ordinary

Everything we do, we do with excellence. From designing bridges to taking meeting minutes, it is all work that matters.

Do More with Less

We are focused and serious about the efficiency and productivity of our office. We all work hard to serve our clients effectively.

Have Fun!

Let’s be honest, engineers are not known for being the “fun” people. Life is too short to not enjoy your time at work, so we prioritize fun in and out of the office.
