Oosterbaan Scaffolding (d/b/a Atlas Bleachers) was established by Garrett Oosterbaan, Sr. in 1959. Atlas Bleachers has been family-owned and operated by three generations for over seven decades. In the 80’s the company expanded into spectator seating for parades and various sporting events. We work as a team with architects, school boards and athletic directors to create customized seating facilities and our commitment to our customers is what sets us apart. What has remained constant throughout this history of transformation is our dedication to our customers, to our employees, and to the values on which Atlas Bleachers was built: integrity, quality, respect, and community.

Atlas values fostering creativity and building lasting relationships with our employees. Our warehouse is located on the southside of Chicago, IL and we travel nationwide to set up spectator seating going the extra “mile” with superior quality customer service. In order to build the most loved bleacher company, we need the most interesting and talented people. Are you one of them? If so, we want to talk to you!

It was a pleasure working with Atlas Bleachers on our Notre Dame football spring game set up. The staff, equipment provided, efficiency of set up and tear down, attention to safety considerations, etc all met expectations and I would not hesitate recommending Atlas Bleachers to others based on our experience. Certainly we would be interested in using your services again if the need arises.

Everything was great. Thanks so much for your help. The seating and press boxes were perfect for the championships. Hope to work with Atlas again in the future.

As the Athletic Director at Niles North High School, I want to personally thank you and your staff for the excellent service you have once again provided installing the temporary bleachers in our stadium. We have always been pleased with the quality of work your company has provided us over the last six years.

My fifteen years as AD has taught me that dependable service from suppliers like you is essential to the smooth operation of our athletic programs. We can't succeed without your support and professional execution of projects. The grandstand bleachers we rent from your firm, Richard, are an excellent addition to our fields and provide a safe seating solution for our spectators.

This letter of appreciation is our way of informing you of our deep appreciation of your efforts. We look forward to continued business with you for years to come.

Athletic Director
Niles North High School
