Traverso Tree Service is owned and operated by John

Traverso, who founded Traverso Landscaping in 1981. 

(He was a nurseryman for six years at Orchard Nursery

in Lafayette prior to that).  To supplement his winter

income John diversified and started doing tree work

along with his landscaping. 


In 1986 he became a Certified Arborist with the

International Society of Arboriculture and found out he

really enjoyed doing tree work.    


In 1989 he decided to concentrate exclusively on the

tree service portion of his business and dropped the

landscaping.  The company has 18 crew members of

which three are Certified Arborists and twelve are ISA

Certified Tree Workers. These certifications guarantee

our customers the highest quality of work.  Education is

very important to John and he has made it a top priority

in his company. He wants all of his crew members to

know how trees grow so that they can better serve

our clients and their trees.

The Company's goals are to provide our clients with

proper tree care in a safe and professional manner.  Our

Motto is, "When it has to be done right, call

Traverso Tree Service." 


John is very active in the ISA and is on the certification

committee which oversees the certification process and is

the coordinator for the ISA Arborist and Tree Worker

Certification program in Concord, California. John is

past president of the California Arborist Association. He is

still involved with the organization by helping to organize

educational & climbing workshops to help newcomers in

the industry. In 2005 John became a Board Certified Master

Arborist, a new certification program with the ISA.  He enjoys

trees so much that he makes them part of his vacation!  He

enjoys planning recreational tree climbs with other experienced

tree climbers as you can see with the pictures on this page.
