Who We Are

Dan's Excavating Service, Inc. is a family-owned and operated business founded in 1997. Our goal is to be a professional, problem-solving firm that completes construction projects with the highest standards of materials and proficiency to exceed customer expectations.

Dan Tellkamp

Founder & CEO

Meet Dan, founder of the “Professional Digg Force”. In 1997, Dan decided he wanted to start his own business in his hometown of Grant, MI. Over twenty years later, he still loves what he does. His background in the construction & farm industry started at the early age of ten when he started work on a local dairy farm. That early beginning was the start of a life long passion for dirt, crops, cows and big equipment that roll black smoke!

Some of Dan’s hobbies are taking care of his cows, snowmobiling, being involved with his church and spending time with his five children (many of whom are involved with the family business)and wife of 29 years, Jackie. If you see Dan rolling down the road, be sure to wave or honk on your way by!
