About Us

About the Firm


Providing Exceptional Tree Care and Fine Gardening Since 1971

Unlike many professional tree service, garden and landscape companies, Les Arbres approaches each property with a sense of community. Our family-owned tree service firm enjoys the stability of career personnel — talented professionals who tend to remain within our organization for long periods of time. Our staff of arborists and tree service specialists, landscapers and gardeners take every opportunity to enrich their individual knowledge and expertise. Our team members share their experience and have deep respect and affection for their fellow employees.

We pay particular attention to the art of listening. We listen to our clients’ ideas, dreams and unique points of view about their home and their trees, landscape and property. We strive for excellence in our work at every opportunity, so it’s not surprising that we attract gifted, reliable professionals.

Les Arbres arborists and horticulturalists are tree service and garden problem-solvers. Each member of our team — the designers, installation specialists, maintenance experts and others — has cross-disciplinary skills that guide and enrich our decision-making process. Every member of our team also possesses inherent knowledge — of music, art, history, literature and philosophy — that extends far beyond the formal boundaries of their job description, and these come into play in our tree service and design specialties.

We utilize wide-ranging knowledge in our work, creating solutions within each landscape that are inspired and informed.  We work together and in conjuction with our clients to build and maintain a free-flowing exchange of concepts, principles and processes. Together we achieve more than any one of us could achieve alone — a concept we embrace for ourselves, for our company, and for our clients.


About Leslie Lewis III (Founder)

Leslie Lewis III has been a practicing Connecticut Licensed Arborist for over 40 years. He began his career working with local tree and gardening services and discovered a natural talent in the arboricultural and horticultural fields. In 1971, he founded Les Arbres and, like the thousands of trees Les has planted, the firm has been growing strong ever since.

For years, Les has taught arboriculture at The Bartlett Arboretum, helping others by spreading his wealth of knowledge and experience. Part of his pro bono work has included the pruning of one of the massive white oaks at the Agricultural Experiment Station in New Haven.

Along with his extensive knowledge of the arboreal arts, Les is well known and regarded for his strong artistic sensibilities. He loves to view each tree as a living work of art that can be nourished, helped and shaped to its fullest potential. That message has been passed down to his son and the other dedicated members of the Les Arbres team he has trained over the years.

“Still Climbing After all These Years”

Still a very active tree climber at age 71, one of Les’ goals is to be the oldest active climber in Connecticut. He is known throughout the area as a quiet and contemplative person, with a reputation for perfectionism in his impeccable work. He strives to ensure that each member of the Les Arbres team thoroughly understands every aspect of the profession, and has a gift for breaking down complex projects into simple, understandable steps that colleagues and clients can appreciate.


About Leslie Lewis IV (Partner)

Les “the Fourth” as he is known, whose father Leslie Lewis III (above) founded the firm, has been fascinated by trees and climbing in them since he was old enough to stand. He says, “I feel so lucky to be able to do something that I love, and to be able to do it with my father, it’s a genuine blessing.”

“Following in his father’s footholds”

Les IV has won two HOBI Awards: Best Landscape Design in 2023, and Best Amenity: Gardens and Legacy Trees in 2018. The HOBI Awards are given out by the Home Builders & Remodelers Association of Connecticut (HBRA) to recognize excellence in the housing industry.

Les has also passed both requisite examinations and is the firm’s second licensed Arborist for the state of Connecticut. The licensing is administered by the Connecticut Department of Energy and Environmental and Energy Protection (DEEP). He passed them on his first try, no small feat in that many professional arborists hold Connecticut’s to be among the top five most difficult exams in the United States. Les is also an International Society of Arboriculture (ISA) Certified Arborist.
