First and foremost, Redi-Rock is a family-owned and -operated business that values hard work and the entrepreneurial spirit. Redi-Rock is owned and operated by the Manthei family, with the 2nd and 3rd generation of the family managing the day to day operations with the same passion and integrity they learned from their forerunners.
Founded in 2000, Redi-Rock was born out of the family heavy contracting business. When a large development required extensive retaining walls, nothing on the market could do the job, so Jim Manthei invented a custom solution that caught on locally and eventually became Redi-Rock International.
With almost a century of business experience behind this family,a constant drive to innovate and improve is a core principal that drives the Redi-Rock business model. Read on to learn more about how innovation has helped shape this family's business ventures.
Redi-Rock isn’t the first successful business for the Manthei family. This family has business roots going all the way back to the 1920s, and producing consistently high quality products is a top priority and hallmark of the Manthei Group of Companies.
In the early 1940s, two brothers, Ted and Ernie Manthei (left to right), were strawberry farmers who wanted to make their own berry baskets. However, after buying a veneer lathe by mistake, the brothers began manufacturing and selling veneer instead.
From humble beginnings, combining vision and diligence, Manthei, Inc. has risen to become one of the leaders in the veneer industry.
Today, Manthei Inc. is owned and operated by the second and third generations of the Manthei family, who provide experience along with creative thinking in forging new paths while continually improving upon existing ones. Manthei Inc. is one of the few remaining family-owned and operated veneer mills in North America.

In 1970, the Manthei group opened Sky Valley Resorts, a group of RV and mobile home resorts in Southern California. Sky Valley Resorts features pools fed from natural, therapeutic hot springs that draw visitors from across North America. Today, Sky Valley Resorts includes space for 1400 RVs and 270 vacation homes.

Initially, the family sold Redi-Rock in Northern Michigan only. As demand grew, brothers Jim, Ben, and Mark Manthei (left to right) realized that they were on to something big. Ben Manthei stepped up as Managing Partner of Redi-Rock and began setting up manufacturers across the Midwest. As the business grew, so did the staff and the manufacturing network.
Today, 130 manufacturers produce Redi-Rock across the United States, Canada, the UK, Spain, Northern Ireland, and the Republic of Korea. Interested in joining the team of manufacturers? Click here to contact us!
