Greenwise Client Relationship Management Team

Your Greenwise Team Is Designed to Give You the Best Service Possible!

We’ve always believed that our attention to customer service is one of our greatest assets (just behind keeping your lawns safe!). In our effort to continually improve your experience with Greenwise, we wanted to update you on who your team is for any immediate concerns. As always, you can email us at or call us at (847) 866-1930 and whoever answers will help you.

The goal of creating our team is to ensure you always have two dedicated customer service representatives at your disposal who know both you and your property.

With our assigned territories, every client relationship manager has a dedicated customer service representative working alongside them. That automatically gives you two consistent points of contact, so that when you have a question or need help, you know exactly who to call to get your answer.

“Creating our client relationship management team ensures we give our customers excellent service. With our team in place, we have a breadth of knowledge and experience and a team that is focused on each of our clients, which helps us respond quickly to our customers’ needs.”

—Austin Hall, Owner & President
