About Us

Our Company History 

At Wirth, Inc. we pride ourselves on being large enough to provide the quality of service you deserve, yet small enough to see that every job has the personal touch you've come to associate with our family name. 

In 1965, after several years in the contracting trade, Ray Wirth, along with his wife, Judy, founded Wirth, Inc. Their dream was to create a superior business based on honest, dependable service dedicated to the homeowner, residential, and commercial customer. Ray and his employees worked long hours to keep up with the demand for his excellent service and installation work. Over fifty years of dedication has built a strong and reputable company. 

Ray and Judy's dream has made Wirth, Inc. the largest plumbing and mechanical business in the Geneseo and surrounding area. Today Ray enjoys retirement and has passed his business knowledge and practices onto his sons and daughters. Ray now serves as Chairman of the Board; Ki is the President and General Manager; Cory and Jason are experienced licensed plumbers; Jodi is the Secretary; and Wendy is the Bookkeeper. Ray's son-in­law, Mark Shannon, serves as HVAC Manager. Ray, along with his dedicated employees, offer their customers the exceptional service that can only come from over 100 years of combined experience. Their hard work, integrity, and customer satisfaction speaks for itself. The company has grown in size to include forty dedicated, and well-trained employees and thirty service and installation vehicles making Wirth, Inc. the unrivaled mechanical contract leader in Henry County.
