About Us

Our firm was founded in the early 1980’s in Ishpeming Michigan and set a standard for quality and integrity. In early 2015 our founder retired and we were purchased by Keith G. LaCosse who has been dedicated to the community of Ishpeming for decades and is proud to carry on the firm’s legacy of excellence.

LaCosse & Associates CPA, P.C. is a full-service accounting firm whose goal is to help clients and businesses with any and all of their financial and accounting needs. We work one-on-one with our clients to analyze their financial situation and give them support and advice that will help them in the long run. It is important to our firm to take the time to listen to our client’s goals and needs. We know how vital financial security is, and we are here to help you develop a tailor made plan to turn those dreams into a reality.
