Foster Trees is a Portland, Oregon based full service tree care company founded by Brad Swet, a certified arborist with extensive experience in the tree care industry. Brad’s passion for trees began years ago while working for the Nevada Conservation Corps as an Americorps member, where he began gaining knowledge and experience in operating chainsaws and working with trees in a forested environment.

He later transitioned out of forest fire suppression and began working with individual tree care in the urban environment of Colorado, where he gained additional expertise with rope climbing and cutting / pruning techniques while gaining familiarity with numerous types of trees and the best way to maintain their health and natural beauty. During this period he also became more knowledgeable in best practices of tree removal where required.

After later working as an ISA Certified Arborist for an Oregon based tree service company for several years, Brad decided to continue pursuing his interest in professional tree care with his own company, and Foster Trees was born.

Foster Trees has grown steadily since it’s founding, predominantly through word of mouth from satisfied clients throughout the Portland, Oregon area. We are a small locally based company that offers friendly professional service many larger companies do not, and provide each of our clients with personalized care when assisting them with their individual needs.

We have a sincere passion for working with trees, and part of our job is to educate clients interested in knowing more about best ways to care for their trees and when and where removal is the best option. We provide clients with accurate assessments and are happy to take the extra time to be sure our customers understand the science and reasoning behind our recommendations when providing estimates.

When you call Foster Trees, you will speak directly to the owner of the company, who will personally come out to inspect your trees and perform every aspect of the job along with qualified assistants as needed depending on the scope of your project.

We hope to be the company you call for all your tree related questions, whether concerned about a tree growing too close to your foundation or roof, concerns about a favorite ornamental tree’s health, orchard or new tree placement, or just someone to call when you feel overwhelmed by a Portland front or backyard that seems to grow faster than you can keep up with it!

As an ISA Certified Arborist, I pride myself on finding solutions that best match my clients’ needs and desires for their trees with the latest knowledge and science in arboriculture.
