Peter Gruenwoldt

Seattle Tree Care Owner and Lead Arborist

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

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.

Favorite Tree: Alpine Larch (Larix lyallii)

Kelsey Gruenwoldt

Seattle Tree Care Owner and Business Manager

ISA Certified Arborist PN-9267A

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!

Jason Harmon

Project Manager

ISA Certified Arborist PN-8359A, Tree Risk Assessment Qualified

Jason has perfected the art of wandering through his own backyard. Born just on the northern tip of Lake Washington, in Kenmore, Jason fell in love with trees while hiking a small section of the Pacific Crest Trail, a path he trekked with his father every year for 15 years. This love of trees was shared equally between father and son, who both became ISA Certified Arborists, proving, once and for all, that the apple does not fall far from the tree. The two ran their own tree service company until Jason’s father retired in 2021, and Jason found his way to the STC team. A place to work that feels like family was just what he was looking for. It didn’t hurt that STC has a fleet of the highest quality equipment in the industry. Jason, his wife Elizabeth, and their chihuahua, Quinn, can often be found road tripping, backpacking, and hiking together.
