John and Sandy Bartos are synonymous with Midland. The Bartos’ involvement in the community over the last three decades has been extensive. They have volunteered in more than 25 state and local organizations and boards.

John currently serves as a trustee for the Charles J. Strosacker Foundation and as a member of the Brownfield Redevelopment Authority. He is on the boards of the Mid-Michigan Innovation Center, MITech+, the Blue Water Angels, and the MidMichigan Medical Center.

The Bartos’ wanted to make a difference in their hometown of Midland. In 1976 they founded The Three Rivers Corporation of Midland. They might have been the only ones who imagined 40 years later that the construction firm they founded would grow to 400 people.

John & Sandy were involved in building several of Midland’s treasured landmarks, starting with the Midland City Hall and in 2007 their company, Three Rivers, was chosen to build the Loons’ state-of-the-art stadium, Dow Diamond.

John grew up on the farm, owned by his family for the past 120 years, that adjoins CopperLeaf.  We are fortunate to still be able to call John and Sandy neighbors.

Cobblestone Homes was founded in the early 2000s by husband and wife team Mark and Melissa Wahl. After graduating from college and pursuing careers, both Mark and Melissa realized that their love for real estate and construction would no longer be a hobby but a passionate pursuit.

Cobblestone was founded on marrying innovation with craftsmanship. Having partnered with some of the leading building manufacturers and building science firms across the United States and Canada, Cobblestone has earned its place as one of the top one percent of custom homebuilders in the United States. Along with many state and national awards, Cobblestone has also been featured on HGTV.

Cobblestone has grown to offer services unlike any other in the Great Lakes Bay Region, offering in-house design, interior design, and customer care services. Team Cobblestone comprises some of the most talented design and tradesmen in the United States. Developing a strong team of individuals who not only have the technical talent, but also the personal integrity, attention to detail, and true care for people has been a driver in the Cobblestone success story.

Mark and Melissa have both served on state and national building associations, and Mark is completing his governor appointed term on the state licensure board. The two have been married for nearly 20 years and live on their horse farm with their beautiful daughter, Shelby.
