About Us

A local IT leader since 1990.

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.

  • We believe in taking care of our clients and our employees, and investing in long-term relationships.
  • We believe in keeping things as simple as possible, using best practices and established industry standard solutions.
  • We believe in the value of an objective expert opinion, and that our advice to clients should be unbiased by an interest in selling hardware or software.

This philosophy has served us well since our founding in 1990, and continues to drive us today.

Our Leadership

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.

Peter Seitel,
Founder & Partner Emeritus

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.

David Leonhardt,
Managing Partner

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.

Martin Rodriguez,
Sales Manager

Judi is a team-oriented manager and creator of legendary “ice cream sandwich day” at the Service Desk. During off hours she’s often cheering on her kids on the volleyball or basketball court.

Service Desk Manager

Our team includes over 30 technical personnel across three offices in Seattle, Tacoma, and Bellingham. 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.
