Our History

JenTer Technologies


JenTer was incorporated by Jan & Wes Okrasinski in September of 2000 and named after their daughters Jenny & Terri. The business started as a part of a larger company where they made wiring harnesses & heaters for a wide variety of different applications. During the first several months after purchasing the business, Wes and a small group of new JenTer associates trekked nearly 2 hours each direction to learn the intricacies of making electrical devices.


Later, Wes & Jan moved the business from Manitowoc to Fox Lake, Wisconsin where it is currently located. The business continued to grow with Commitment to Customer Service, Attention to Detail, Focus on Quality, and Delivery of Superior Results - all traits which JenTer continues to pride itself in. Over the next 10 years, two external building additions were completed and two internal mezzanines were added to effectively triple the original production space.
