Bill Lang

President

Following his father’s footsteps, Bill Lang Jr. has been part of the Certified family for over 30 years. As President and CEO of the company, he has built upon the foundation left by Bill Lang Sr. to improve and expand the company to new heights. Regardless of how big Certified becomes, however, Bill wishes to maintain the same family-like dynamic that has led the company to prosper since its early beginnings.

Sam Lang

Vice President

Graduated from Loyola University Chicago with a bachelor’s degree in Business Administration and Operations Management, Sam is putting to use what he learned to help Certified grow and improve. Though he has been working for the company since he was a child, he still has much to learn about the fastener industry and looks forward to working with the rest of the Certified team along the way.

Lonnie Barna

Sales Engineer

Lonnie has been in the fastener industry since the invention of the wheel, first as an expeditor and then a buyer. He then went on to sales and sales management. Having great interest in the products propelled him into problem solving and application engineering, which he then applied to Certified and has been an invaluable member ever since.

Bob O’Brien

Sales Executive

As one of our leading fastener experts, Bob has been with CFIS for over 15 years and in the fastener industry for over 40 years. In the past, Bob has been a certified internal ISO auditor, and takes an active role in the quality process at CFIS. He was also a board member of the Midwest Fastener Association where he has served both as the President and the Treasurer.

Patricia Johnson

AP/AR Manager

Patricia has been with us for over 25 years and has played a fundamental role in Certified’s success. Patricia handles many of the office responsibilities – such as our accounting and finances – that keep Certified running. Just pay those bills on time so she won’t come running after you next!

Herbert Estacio

Warehouse Manager

Herbert is the man behind the scenes that makes sure our customers get their orders on time. As Warehouse Manager, Herbert has done tremendous work improving our operations. Some of his accomplishments include: reorganizing the entire warehouse and its inventory, streamlining operations, and improving overall efficiency within the workplace. A tech-wiz and incredibly quick learner, he has gone above and beyond his responsibilities to help the company succeed.

The Warehouse Team

Although they did not receive individual descriptions, there’s no question that every member of our warehouse crew is invaluable to Certified’s success. They always do their work and do it right, and they never fail to cause a laugh for the employees and customers. A huge thanks to every one of them for all of their hard work and dedication over the years!
