About
Treaty Supply Greenville
Since our founding in 1902, Treaty Supply has been a trusted and preferred supplier for the commercial, residential, multifamily, manufacturing, and service sectors throughout Western Ohio and Eastern Indiana. Based in Greenville, Ohio, we proudly offer a wide range of products from industry-leading manufacturers such as Kohler, Rheem, Sterling, and Moen, allowing us to meet virtually every project need. Our long-standing reputation is built on reliability, product knowledge, and a commitment to helping our customers succeed.
Treaty Supply is part of Hajoca Corporation, a company with roots dating back to 1858, when a single entrepreneur invested $200 to begin serving plumbers in Philadelphia. More than 150 years later, Hajoca has grown into a national leader while continuing to shape advancements in the plumbing industry. This success is driven by a unique business philosophy and talented people, blending the strength and resources of a large organization with the flexibility and personal focus of a local business.
While Hajoca’s reach is broad, its approach remains local. Treaty Supply operates with the independence to serve our community’s specific needs, from the products we stock to the people we employ. Our team members are dedicated professionals who value service, integrity, and reliability—and they are also your neighbors. By combining local insight with the support of a strong national network, Treaty Supply delivers exceptional service rooted in quality people and lasting relationships.
