Company History


President and founder Mary Ellen Cook started in the janitorial service industry in 1980. When the company she was working for went out of business she was asked by the client to remain and Cook’s Industrial Cleaning was created. In 1999 the company had grown to over forty clients, and became Corporate Cleaning Inc. Sheri Flahive became Vice President and our company continued to grow all through word of mouth. Corporate Cleaning merged with Sunshine Cleaning of Muskegon in 2006. This acquisition has expanded the company’s capabilities and coverage in the Western Michigan Region. We service everyone from the small one man office once per month to 200,000 sq. ft complexes seven days a week, all with the dedication to quality that you should expect from a contractor with the attention that only a small family business can offer.
