Meet Our Team


Jim DeGrado


Founded in 1995 – After graduating from Colorado State University in Pueblo, Jim took the traditional path and worked for a Fortune 500 company. In 1995, during the mid ‘90s housing boom, Jim left corporate America to start CDI. Jim coupled his prior experiences from working in the family landscape contracting business, in rural Colorado, with his formal education in Business Management to start his new venture. His hard work and perseverance quickly blossomed his business model into CDI servicing all of Colorado, with seven different environmental divisions. Jim has extensive field experience in every aspect of CDI’s service offerings. He has personally performed and trained at every position at CDI. Extremely active in day-to-day operations, Jim brings guidance, inspiration and dedication to the fast-paced atmosphere of a company experiencing healthy growth. Today, even though CDI has become one of the Rocky Mountain’s largest Environmental Services companies, Jim pledges “CDI is big enough to serve you BUT small enough to know you”.

Vice President/COO

Zacc started at CDI in the Landscape Maintenance Division chasing a lawn mower.  He showed his dedication and ability to learn CDI’s business as he climbed the ranks: Foreman, Superintendent, Estimator until he earned his Manager stripes in CDI’s Erosion Control Division.  Then, during the housing boom of 2013, Zacc recognized CDI needed to start a new division coordinating Civil & Soil Management offerings which has grown into CDI directly managing/hauling hundreds of thousands of cubic-yards of soil each year.  Now, after all his experiences throughout CDI, Zacc has earned the title of Vice President/COO and is responsible for all day-to-day construction operations for all seven divisions.
