St Louis Lawn Care | Hansen's Tree Service

Hansen’s Tree Service is a Treemendous Company

Hansen’s Tree Services was founded by Jeff Hansen in 1988. Hansen’s was the first tree-care company in Missouri to be certified by the Tree Care Industry Association. Hansen’s employs 10 International Society of Arboriculture-certified arborists, making the company one of the most accredited tree service companies in the St. Louis area.

Hansen’s owes much of its growth to the diversification of services as well as its philosophy on employee education. The company not only provides residential and commercial services such as tree diagnosis, treatment for sick trees, pruning, tree removal and stump removal, but also has expanded into other areas. Among these are Hansen’s mobile grinder, lawn care, mulch and firewood services and compost. In all, Hansen’s employees 90 people and operates a fleet of 75 trucks.

Mission:
The entire staff of Hansen's is guided by a three-point mission:

To educate the public on safe and proper tree care techniques, and to maintain a commitment to our own education so we're constantly able to provide the best information available.
To perform our job to exceptionally high standards, both in our tree and lawn work, and in our relationships with customers.
To be a resource of information and expert tree care advice to the residents, companies and organizations that make up the communities we share.

History:

Believe it or not, Hansen's Tree Service all started as a side job. Back in 1988, Founder and President Jeff Hansen, a longtime BFI employee, started trimming trees a few Saturdays per month so his wife could stay home with their children. Word started to get around, and the side job started becoming more regular, and even a bit overwhelming. With his employer's blessing, Jeff decided to turn the business into a full-time venture.

In 2001, we began offering our tub grinding services, which has allowed us to diversify services by offering recycled 100% organic mulch. We now have various grinders, both tub and horizontal, and are able to offer compost and select firewood as well.
