About Us

A local IT leader since 1990.

Seitel Systems is an IT engineering and consulting firm that was first established in 1990 as Seitel Leeds & Associates before becoming Seitel Systems, LLC in 2006, and now Seitel Systems, Inc. in 2022 (an ESOP Company).

The Seitel Systems difference comes down to one central principle that guides everything we do:

Treat our clients and employees like real human beings.

We believe that a successful business is a collection of like-minded people who have a shared expertise, passion, or mission that unifies their work.

Our Core Values

Our expertise is in solving technical problems, and our unifying purpose is to create solid IT infrastructure that allows businesses to flourish by freeing teams to focus on what they do best.

Our roots stretch back to 1990, and the philosophy that guided us then still drives us today with great success.

Our Leadership

Peter Seitel

Founder & Partner Emeritus

Our founder Peter “graduated” in 2015 (don’t you dare say “retired”), and can now generally be found bicycling the back roads, spending time with his family and friends, or volunteering as a math tutor.

David Leonhardt

Managing Partner

David has served in a variety of roles in the technology business since 1989. After hours you’ll typically find him playing soccer or cheering on the Sounders.

Martin Rodriguez

Sales Manager

Martin has been a part of the Seitel Systems “family” since 1997. He is sought out as a trusted advisor when clients need to find solutions to their IT problems… and also for his famous homemade tamales.

Judi Baker

Service Desk Manager

Judi oversees the day-to-day operations of the Service Desk and manages the team of support technicians. 

Jeff Custer

Project Services Manager

Whitney Hanson

Senior Engineer

Brian Simpson

Senior Engineer

Michael Eisenhart

Our team includes over 30 technical personnel across two offices in Seattle, and Tacoma. We are proud of the quality of work life we’ve created here, and the camaraderie you’ll find among our team.

Everyone on our team plays a vital role in supporting our brand and our way of doing business. As a result we set high standards for not just technical skills, but also for inter-personal skills, initiative and overall commitment to the larger client and Seitel Systems’ team.

Check out the biographies of our leaders, and you’ll immediately sense the difference. Our clients look to us first to keep their technology infrastructure happy & healthy, but they also look to us to be their trusted advisor and colleague.
