    About Us

    Mission Statement: Portland Tree Service is committed to providing quality professional and sustainable tree care and tree services while maintaining high standards of safety, efficiency, and customer satisfaction.

    Portland Tree Service is owned and operated by Oregon native, Aaron Krieger. His passion for arboriculture was born from his love of outdoor recreation. Restless working a traditional office job, he started his outdoor career as a Wildland Firefighter, and is now licensed by the Oregon Construction Contractors Board (CCB #198715), an ISA Certified Arborist (PN-8224A), who is also TRAQ qualified (Tree Risk Assessment Qualified). He is extremely knowledgeable about the Pacific Northwest plant life, landscapes, and forests, and continues to educate himself on a personal and professional development level.

    PTS is now comprised of staff and crew members who are as passionate about our PNW forestlands and urban treescape as he is. We don’t just work outdoors, we play outdoors: hike, bike, snow, and camp. We also give back to local trail building and park projects by volunteering time and resources to ensure our outdoor recreation lands are protected and maintained for future generations to enjoy.

    Portland Tree Service is locally owned and operated. We love the PNW and are committed to preserving its awesomeness through trees.
