Keesen Landscape employee Stella Perez celebrated her 19th anniversary as an employee.

Keesen Enterprises, Inc. was founded in 1972. More than 40 years later, the company is still growing and thriving, having built a reputation for reliability, quality work and outstanding customer service. Many of our customers have been with us for years, and we enjoy a very high annual renewal rate in an industry that generally experiences extremely high customer turnover. In 2016, we joined forces with other landscape industry leaders to become a Heartland company. Heartland is dedicated to putting people first, building relationships and delivering exceptional service across Denver, Colorado. Together, we operate with a shared vision of excellence—combining the best practices with the right tools to put our team, our clients and their customers first—giving our all, in everything we do, every single day.
