Celebrating 50 years of Excellence:

The OTTO Dream:
With confidence in his ability and faith in the American dream, Jack Roeser started OTTO in the basement of his Park Ridge, Illinois home in July of 1961. Jack used an initial investment of $5,000, along with his military, business and engineering experience to design push button and rotary switches.
OTTO Makes the Move:
By 1968, OTTO had developed a solid reputation as a high-quality switch manufacturer. Floor capacity in Morton Grove was being pushed to the limit and it was time to expand. The town of Carpentersville, located about 30 miles west of Morton Grove, had space available at an abandoned liquor store. OTTO purchased the building and sold the leftover liquor inventory, coolers and refrigerators to help pay for the building. Carpentersville became OTTO’s permanent home.
Tom Roeser joins OTTO:
In January of 1987, Jack’s son Tom joined the company as General Manager and assumed responsibility for OTTO’s day to day activities. By applying his knowledge and experience, as well as his life history growing up in the shadow of OTTO, revenues continued to climb rapidly. The combination of Jack’s entrepreneurial spirit with Tom’s business acumen and engineering skills solidified OTTO’s foundation as a world class engineering and manufacturing organization.
OTTO Focuses on the Future:
OTTO now begins the journey through the next half century. With OTTO’s focus on new product development and value-added services, OTTO is prepared with new equipment, room to expand and a growing staff. Plans are in place to continue OTTO’s focus on meeting the needs of customers with demanding applications around the globe. Because of OTTO’s vertical integration and ability to engineer value into specific product designs, customers seek OTTO’s expertise in solving challenging problems.
Keeping the OTTO Culture:
A strong family bond flows throughout the organization and at the root of OTTO’s success is the fine employees who arrive every day and commit to total customer satisfaction.
