Mattawan, Michigan

"The thread that connects us is the fact that we impact millions – every room clean, welfare check, and meeting makes a difference. From the grandparents who desire to watch their grandchildren grow, to parents who want a quality of life for their family, and children who dare to dream, we impact those lives. those lives matter to all of us. What we accomplish today, will change the world tomorrow.” – David M.

Living in Mattawan

Our Mattawan facility, located in Southwest Michigan, is halfway between Chicago and Detroit. The site is only 10 minutes away from Kalamazoo (yes, there really is a Kalamazoo!), which is well known for Gibson guitars, hiking trails, and local breweries.

The opportunities to explore our wonderful lower and Upper Peninsulas are endless. One can easily travel any direction to find something beautiful, such as Mackinaw Island, wine-taste on Old Mission Peninsula, and cruise the snowmobile highways of the Upper Peninsula. Many amenities include county fairs, watching an afternoon Tiger’s game, a concert at the Fillmore, or cheering on two of our big 10 Universities.
