About Us

Edward T. VerHalen, Sr., founded VerHalen, Inc. in 1911 as a sole proprietorship in Milwaukee, Wisconsin. Though the Company was owned and operated by Mr. VerHalen, he was eventually assisted by Edward S. VerHalen, Jr., and Harvey M. Nelson, who joined the Company in 1936 and 1937, respectively. Upon Mr. VerHalen’s death in 1950, Edward Jr. and Harvey were elected to take over the corporation and conduct business as equal partners.

VerHalen grew under the guidance of Mr. VerHalen, Jr. and Mr. Nelson, adding additional sales offices in Madison and Green Bay. In 1968, William H. Calawerts joined VerHalen as General Sales Manager of the Green Bay operation. In 1980 Bill and his wife, Norma, purchased VerHalen and Mr. Calawerts moved the Company headquarters to Green Bay. Under the leadership of Bill Calawerts, the Company continued to grow with offices in Green Bay, Madison, Brookfield, Appleton, and Greenfield.

In 1997 management of VerHalen was assumed by Bill’s sons, John, Chris and Mike. In 2015 the business decision was made to brand the divisions independent of one another creating VerHalen Construction and Pella Windows and Doors of Wisconsin. In 2023 John and his wife Anne purchased 100% of VerHalen. John, as President, oversees the management of the company.

In 2025 John and Anne built a new 85,000 square foot showroom, warehouse and office at 2423 French Road in De Pere, WI. Today, Pella Windows & Doors of Wisconsin has showroom locations in De Pere, Brookfield and Madison.
