About Us

changing the game in customer service and property care

Family-owned and operated, we genuinely care about the health and well-being of your trees, shrubs, and lawn.

How It All Began

Mark Nega, Green Doc president and consulting arborist, spent several years working for large companies doing what he loves most: providing healthcare for trees, shrubs, and properties.

As time passed, Mark began to imagine new possibilities. When it came to customer service, Mark knew there must be a better way. That’s when he started Green Doc.

Since 1998, Green Doc has been providing property owners throughout the Chicagoland area with the premium tree, shrub, and lawncare they deserve.

You can be assured that Green Doc will provide high-quality, customized care to help your plants thrive.

Our Expertise

Mark has been a certified arborist for over 20 years. With a Bachelor of Arts degree in Environmental Resource Management, Mark has over 25 years of experience.

When you work with Green Doc, you can rest assured that your property is in good hands. Mark and the team will regularly assess your landscape and proactively address problems before they become major issues.

Our holistic, scientific-based approach will help ensure your landscape is at its healthiest not just today, but for years to come.
