Proudly serving Colorado for 70 years

The History of Swingle

I’m Tom Tolkacz, the CEO of Swingle Lawn, Tree & Landscape Care.

Seventy years ago, John W. Swingle started his own business – unaware it would grow into one of the most respected and innovative landscape care companies in Colorado. This year marks Swingle’s 70th year of proudly caring for Colorado outdoors.

In 1947, John founded Swingle Tree Surgery Company out of the back of his old, reliable Jeep. It has been said that John would climb high into the trees in order to properly prune them, while his wife would stand at the ready below. John would safely lower the branches he removed to the ground, where she would then stack them neatly in the back of their Jeep for disposal. They were a well-oiled machine destined for growth.

John’s incredible knowledge of arboriculture and his mind for business, combined with his unwavering dedication to his customers, enabled the company to expand rapidly. Quality workmanship, and keeping up with the latest technologies became Swingle’s standard – his motto, “stay ahead of the pack.”  

Sadly, just as John Swingle’s dream was being fulfilled, he passed away in September of 1956. At that time, leadership of the company transferred to Earl Sinnamon, a former Denver City Forester and lover of the outdoors. Under Earl’s direction the Company flourished as a leader in professionalism, credibility, and reliability – upholding the Swingle motto, “stay ahead of the pack”. In 1978, Earl revolutionized the industry by purchasing a computer system, long before his competitors. It was this type of foresight that brought the Company successfully into the 1980’s.

Upon Earl’s untimely passing in 1980, a partnership was formed between two long time Swingle employees, Dave Dickson and Charles Morgan. Dave and Chuck remained dedicated to the progressive philosophy formed in the Company’s early years that separated Swingle from competitors in the industry. They adhered to basic ideas such as quality service and exacting standards.

In December 1988, Chuck Morgan retired and Dave Dickson became Swingle’s new President. With over 30 years of service at Swingle, Dave remained committed to personal service, quality through innovation, and controlled growth by limiting the geographic areas of Swingle lawn care and tree services.

When I became the CEO of Swingle back in 1998, I had already been with the company for 11 years – fully aware of John Swingle’s legacy and philosophy to, without exception, do right by the customer, the community and the environment. After decades of strong growth, Swingle continues to support that philosophy with offices in Denver, Fort Collins and most recently our location in Firestone.

We still firmly believe that investing in our employees is paramount to our success. We continually set the standard for knowledge, experience and professionalism within our industry. We strive to do the best job possible by reinforcing trust and fostering the long-term relationships for which we are known for throughout the community.

We owe our success to the people of the Colorado Front Range – the homeowners and commercial property managers we’ve been honored to serve over the last 70 years. Thank you for the continued opportunity to care for your lawn, tree and landscape needs. We’re always here to answer any questions regarding your landscape so don’t hesitate to contact us.
