Though there rarely seems to be much free time, both Dave and Tom believe in giving back through their profession to worthwhile causes. Through donation of their professional services at little or no cost to the client, many organizations have benefited. Currently we are working with ARK, a non-profit wildlife rehabilitation center in Roscommon County. Last year we provided all of the design services for the Houghton Lake Little League Complex, which was inspired by a young area ball player who died after being hit by a drunk driver.

We always set aside time for projects like these so let us know if we can work for your cause.
