about us

We Stand Behind Our Core Values

RSI Manufacturing began in 1995 as Re-Source Industries, Inc. Through the years our specialty has evolved from uncomplicated production machining using custom-built special machines to complex, precision, production machining and assembly using CNC machines. RSI relocated to Muskegon, MI from Coopersville, MI in 2004, with over 30,000 square feet of manufacturing space.  

RSI takes great pride in offering our customers comprehensive and well-engineered solutions to their manufacturing challenges. With over 25 years of experience and hundreds of implemented solutions, it’s no wonder that RSI has been the choice of so many innovative businesses!  

In August of 2020, RSI was acquired by Waseyabek Development Company (WDC). WDC is the economic diversification arm of the Nottawaseppi Huron Band of the Potawatomi Indians. WDC’s mission is to acquire and grow non-gaming companies and business assets to diversify the Tribe’s revenue stream and create quality career development opportunities for Tribal Members. RSI now operates under the name RSI of West Michigan, LLC and joins other companies, such as Baker Engineering, LLC of Nunica, MI in the WDC manufacturing group.
