Peter Gruenwoldt

Seattle Tree Care Owner and Lead Arborist

ISA Certified Arborist PN-6127A , ISA Qualified Tree Risk Assessor

Peter’s love for trees runs deep and started young. Growing up in a small Western Washington rural community, Peter started learning about trees at an early age alongside his father, a U.S Forest Service Forester and ISA Certified Arborist. Peter’s initial exposure to Forestry was on long hikes with his father cruising old growth timber stands and collecting data about spotted owl habitat. Climbing to the highest vantage point has always been second nature to Peter, and he spent many days of his youth rock climbing in the Pacific Northwest, Alaska and California. Peter studied Environmental Science at the University of Redlands, and then combined his love of climbing with his love of trees, and became a proficient and skilled tree climber working for several different companies in the Seattle area.


Knowing that there was an extra level of depth, sustainable practices and customer service he could provide, Peter founded Seattle Tree Care in 2006. A husband and father of three, Peter will always put your safety and the enjoyment of your property first. Peter is committed to creating the maximum benefit that trees and people share and is grateful to work with your amazing Seattle trees while practicing the art and science of responsible tree care.

Kelsey Gruenwoldt

Seattle Tree Care Owner and Business Manager

Kelsey is a fourth generation Seattle native with a great appreciation for this beautiful region. She earned her BA from the University of Washington in the Program on the Environment (2003), an interdisciplinary degree that included Forestry classes. In her studies of old growth forests she learned Tree Identification, Stand Management and Tree Assessment. Post University Kelsey worked as the Director of a local environmental company with a mission to help sustainable businesses grow. When her first child was on the way in 2007, Kelsey decided it was time to help build her own family business. She took her HR, bookkeeping and managerial skills, and put her energy into shaping and growing Seattle Tree Care.


To this day Kelsey loves making sure that the Seattle Tree Care team is at the ready to provide an outstanding experience for your tree care, because a lifetime spent in Seattle means Kelsey knows that when the sun shines we all want to enjoy the great outdoors!
