A trusted arborist
Stef Ringgenberg founded Boulder Tree & Landscape Company in 1972. For 32 years he treated trees for customers in the Boulder Area until the company was sold. Boulder Tree was a full service tree service that did pruning, insect and disease control, fertilization, and anything else related to the care of trees.
During those years, Stef became a recognized expert on the care of trees. He was on the Board of Directors of the International Society of Arboriculture and is designated a Certified Arborist by that organization. Stef was also a Registered Member of the American Society of Arboriculture for many years.
Boulder Tree & Landscape Consulting no longer does the physical work but now gives advice on tree care. Stef is a tree doctor who can diagnose what’s wrong with your sick trees, but a better idea is to call Stef before the trees get sick. He can give you a plan to keep your trees healthy!
