About Us

Ralph & Betty Sixel

In 1957, Ralph Sixel started his own electrical and plumbing business and named it R. L. Sixel Electric. Ralph worked on his own out of his garage on Dairyland Drive. As his business grew, his sons, Gary Sixel and Jeff Sixel, along with Leonard Schwinn came on board. After many years of work they were able to expand into a larger shop.


After 28 years in business, Ralph retired on December 31, 1985. Gary, Jeffrey & Leonard purchased R. L. Sixel Electric and renamed it Sixel & Schwinn, Inc.


In 2001, Scott Sixel and Mike Milbrath became partners with Gary, Jeffrey & Leonard. Soon after, as the business continued to grow, land was purchased to build a new shop located at N7677 Rangeline Road, Sheboygan, which is our workplace today.


In 2012, Gary relinquished his ownership with Sixel & Schwinn, Inc., but remains a part- time employee.


On January 1, 2016, both Jeffrey and Leonard relinquished their ownership. Leonard has retired and Jeffrey remains as an employee through December, 2016. On January 1, 2016, Andrew Schueler and Michael Baumann joined Scott and Mike to become the current owners of Sixel & Schwinn, Inc.


In the past 50 years, our highly qualified employees and the commitment to our customers has made Sixel & Schwinn, Inc. the dedicated business that we are today.
