Erik Gustafson - ISA Certified Master Arborist RM-7467B - Owner/Sales Representative/Co-President

My passion for everything outdoors began young while growing up in Western New York, and has carried with me into my professional cErik Gustafson Arboristareer. After high school, I attended community college where my passion for the outdoors developed into a fascination with trees. I then attended the State University of New York’s College of Environmental Science and Forestry (SUNY-ESF) in Syracuse, receiving a BS in Forest Health.

I went to work after college for Bartlett Tree Experts, and then decided my love for mountains   and climbing would bring me to Colorado in 2010. I am now an ISA certified master arborist  and a Qualified Supervisor (#26098) with the Colorado Department of Agriculture for pesticide applications in multiple categories including ornamentals and forestry.

I feel that my education and experience allows me a unique perspective on the issues affecting   our native and urban forests and am excited for the opportunity to live and work here in this incredible part of the country.

Keith Boarman - ISA Certified Arborist RM-7501A - Owner/Climber/Crane Operator/Co-President

I started out my professional life in the Army as a Green Beret. When I got out of the Army I found a job as a tree climber. I fell in love with tree work. It has all the rigor and excitement I  enjoy and you get the gratification of helping to maintain our urban ecosystem.

Prior to starting Patriot Tree company I worked at many various companies in both Colorado and New York, both as an employee and as a subcontracting arborist. I noticed a large demand for high quality and affordable tree services in Boulder County. At the same time I noticed quality and customer service severely lacking in some of the companies I was working for. I was also very irked by the overuse and abuse of chemicals for plant health care.

When I started Patriot Tree company I took many lessons learned in both Arboriculture and in the Army Special Forces to create an excellent tree company. We are a team oriented company and we pay attention to detail. I make sure our team takes great pride in everything we do from the trickiest removals and the finest pruning job to cleaning up a small aspen stand or shearing some hedges.

I also strive to make sure we have the right equipment and skills on hand to offer any level of tree service, so we are a one stop shop forall of the trees on your property.


Michael Boarman - Tree Climber


Since I was very young I have had a great love for everything outdoors, because of my love of the outdoors I decided to pursue a degree in Forest Health from The SUNY school of Environmental Science and Forestry in Syracuse NY.  After receiving my degree I moved to Colorado and began working in tree care.  I started at one of the oldest and largest tree services in Colorado where they taught me the ropes.  Tree work came naturally to me as my education and love of physical activity helped me to excel.  When an opportunity to work here at Patriot Tree Co. for my brother came up, I jumped on it.  I really enjoy the small company atmosphere.  It allows for a higher commitment to quality and I truly feel we are one of the best tree crews around.
