About Buffalo Supply

Buffalo Supply was established in 1983 when a medical device sales representative determined there was a need for specialized, small business distributors in the government sales channel that would support both healthcare manufacturers and federal healthcare facilities.  Buffalo Supply continues to evolve to meet the needs our customers and manufacturing partners, by holding multiple federal contracting vehicles, making sure our service members and veterans have access to the best healthcare devices and supplies available.  In holding these contracts directly with the federal government, BSI ensures we maintain compliance with all of the Federal Acquisition Regulations (FARs) and any other regulations that apply, at the order/task level and at the national level.  With nearly 40 years of experience in the federal market, you can count on BSI to make the process as easy as possible.  Government.  Simple.

At Buffalo Supply, we believe in true customer service. When you call us, you always get to talk to a real person, right away. We are always happy to help you.
