Our Company
Rooted In Relationships
For more than 50 years, Keesen has helped care for commercial landscapes across Colorado through dependable service, responsive communication, and long-term client relationships. Since 1972, our team has partnered with property managers, ownership groups, HOAs, and facilities teams to support outdoor environments that are used, experienced, and relied on every day.
We believe strong landscapes are built through consistency, attention to detail, proactive planning, and long-term property care. That mindset continues to shape how we approach landscape maintenance, irrigation management, snow and ice response, seasonal enhancements, and ongoing property support throughout Colorado’s Front Range.
Our Mission
Keesen exists to support commercial properties through reliable service, proactive communication, and thoughtful landscape care built around the long-term operational needs of the properties and communities we serve.
Our goal is simple: communicate clearly, follow through consistently, and build relationships clients can rely on season after season.
Behind every Keesen property is a team of account managers, field crews, irrigation specialists, enhancement teams, and snow professionals committed to responsive communication, operational consistency, and long-term client relationships. Our people are what make the Keesen experience different.
Our History
Keesen was founded in 1972 with a commitment to dependable service, strong relationships, and quality work. More than five decades later, those values continue to guide how we operate and support commercial properties across Colorado.
Through industry changes, economic shifts, major winter storms, and even the loss of our headquarters in a devastating 1998 fire, our team has continued to adapt, grow, and support the clients and communities that rely on us every day.
In 2016, Keesen became part of HeartLand, joining a network of commercial landscape companies that share a people-first philosophy and commitment to service excellence. While the company has continued to evolve, our focus remains the same: take care of people, communicate clearly, and do the work the right way.
Keesen maintains active involvement in professional organizations that support high standards in commercial landscaping, irrigation management, safety, and environmental stewardship. Through continuing education, industry partnerships, and ongoing training, our teams stay informed on evolving best practices, regulatory standards, and operational efficiencies across the industry.
