“The Calder team truly understood what mattered most to me: ensuring Thornapple’s people and customers would be well cared for. Their dedication to that end exceeded my expectations. After vetting multiple offers, we determined that the best succession plan, one that would honor our past and place us on the best path forward, was the one that involved someone I have known and worked with for several years. I am grateful to have gone to market through Calder, to have met with strategic and financial buyers, and to have obtained the assurance that Scott is the best successor.”
– Josh Rich, Former Owner, Thornapple Excavating, Grand Rapids, MI (Seller)
“The dynamic of purchasing a company from someone who happens to be your employer is quite unique. However, between my existing friendship with Josh and the courtesy that Marc extended, the process couldn’t have been any better. Marc did a tremendous job representing Josh and walking me through the process.”
– Scott Dore, Owner, Thornapple Excavating, Grand Rapids, MI (Buyer)
Calder Capital is pleased to announce the successful sale of Thornapple Excavating, Inc., a leading excavating and site preparation contractor based in Grand Rapids, Michigan, to individual entrepreneur Scott Dore, also of Grand Rapids, Michigan.
Originally named Hulst Dozing, Thornapple Excavating was incorporated in 1985. Thornapple Excavating is a premier commercial excavating company providing clearing, demolition, earthwork, utility installation, and site preparation services throughout West Michigan. The Company has become synonymous with quality, precision, and reliability, leveraging advanced CAT machinery and GPS technology to deliver superior results. Under the leadership and ownership of Josh Rich since 2016, the Company has continued to grow substantially. Rich engaged Calder Capital’s Sell-Side team to find a successor aligned with Thornapple’s values and long-term legacy.
Rich found himself spending more time on office and administrative duties, tasks that didn’t align with his passion. Through the sale, he aimed to return to what he enjoys most: operating heavy equipment, moving dirt, and meeting with customers one-on-one. Rich is looking forward to pursuing these passions in his new venture, Airport Aggregate.
Scott Dore, longtime Estimator and VP of Operations for Thornapple Excavating, acquired the company from Josh Rich. Dore’s intimate understanding of the Company’s culture and client relationships ensures that the company will continue on its growth trajectory. His acquisition ensures continuity in leadership, quality, and customer commitment that have been hallmarks of Thornapple’s reputation for over 50 years.
Rich shared, “I’m confident that Scott will continue to build upon the foundation that Thornapple was built on: integrity, excellence, and a commitment to doing things the right way for our customers and our people. Having worked with Scott, I have complete faith in his ability to lead Thornapple Excavating into the future.”
Dore expressed enthusiasm for the opportunity ahead, stating, “I would like to thank Josh for this Great opportunity he has offered to me in buying the business. My future goal for the growth of the company is to surround myself with great people that will help me take the company to the next level using all our past and future experiences.”

Dore complimented the Calder team, adding, “The dynamic of purchasing a company from someone who happens to be your employer is quite unique.
