It All Started...

Before Earthadelic was Earthadelic, it was a small lawn care company that now co-owner, Dale Madden, started as a kid. Dale always had an interest in plants and outdoors, which he turned into a small lawn care business. After he graduated from the University of Tennessee, he decided to continue his business out of his passion for being outdoors and his eagerness to engage with customers.


In 2006, Steve Polte joined the company and became Dale’s business partner. Steve, who obtained a Bachelor’s degree from Cornell and an MBA from the University of Tennessee, brought 30 years of experience and knowledge to the table. With Dale’s passion for landscape construction and Steve’s business knowledge, they began the journey that has led them to a successful partnership and company.
