About Guenther Supply, Inc. Starting a small business back in the 1940’s and early 1950’s, Gordon Guenther, along with his brother Marvin, built walk-in coolers, refrigeration equipment, and retailed plumbing, heating, and refrigeration supplies.

In 1956, Guenther Supply was founded when Gordon Guenther and Lyle Trader ventured into the wholesale supply business, selling plumbing, heating, and refrigeration supplies, then adding petroleum-handling equipment.

In 1963, Raymond Zwicky joined the firm, providing valuable business experience to the young company. Ray served as President of Guenther Supply, Inc. from 1972 until his retirement in 1990.

Through the next few decades and into the present, Guenther Supply, Inc. grew consistently. To meet customers’ needs, Guenther Supply added new product lines of pipe, valves and fittings, and related items. New facilities were put up to house the increasing inventories.

Today we have a fully integrated computer system offering real-time inventory availability. We have a busy shipping department and a fleet of delivery trucks to get our products to our customers. And we continue to grow.

Keeping pace with modern technology, we offer our customers the most innovative tools and products in the market. We have a knowledgeable full-time staff working together and dedicated to customer satisfaction.
