Joseph Sutton-Holcomb

Senior Arborist

Joseph is an arborist and horticulturist who leads our Integrated Pest Management Program. He specializes in plant health care, residential tree assessments, risk assessment, interpreting municipal tree codes, plant appraisal, and pneumatic (air) excavation. His project resume at Tree Solutions Inc. includes tree protection during construction and large-scale tree inventories. Joseph has over 10 years of experience in the environmental sector, giving him a wide and eclectic foundation of knowledge. His previous experience designing, installing, and managing landscapes and green stormwater infrastructure provides valuable background for his consulting work at TSI.  

When he isn’t studying trees, Joseph enjoys bicycling (on and off road), hiking, camping, and overenthusiastically dancing to live music.
