Hoyt Arboretum Friends' Seeks New Executive Director

Dear Friends of the Hoyt Arboretum:

Seventy-seven years ago the City of Portland designated land to become the Hoyt Arboretum. From its beginning, our founders intended to preserve the area for a diverse collection of species with a goal of ensuring everyone had free access to a unique living museum.

We have come a long way since then, and Hoyt Arboretum has matured into a special place where we now grow and exhibit over 6,000 trees and plants from around the world. We continue to rely upon volunteers, and access remains free of charge. Last year alone we provided hundreds of hours of educational opportunities, managed 11,000 hours of volunteer service, survived a landslide, installed Hoyt Arboretum’s first weather station and increased membership to an all-time high.

Five years ago, like many other organizations and individuals, Hoyt Arboretum was facing financial difficulties. Through the leadership and creativity of our Executive Director, Peggie Schwarz, and the dedication and hard work of our Board, we have righted the proverbial ship and I am proud to say that Hoyt Arboretum Friends is again a strong and financially sound organization.

I congratulate Peggie on her accomplishments, and on her recently announced retirement. While her departure is bittersweet, I am eternally thankful that Peggie dedicated her past five years to Hoyt Arboretum Friends. We wish her all the best and expect to see her out walking our trails and hopefully volunteering in the arboretum.

A search for a new Executive Director is already underway and we expect to complete our search later this year. The Board has retained the services of the Nonprofit Association of Oregon to assist us in finding someone who can help us maintain our outstanding financial strength, expand our educational programs and move Hoyt Arboretum to the forefront in our community.

The Board is also simultaneously updating our strategic plan because we have, through the hard work and dedication of many, accomplished virtually all of the goals set back in 2012. The timing is good as we will be able to hand our new Executive Director a new strategic plan at the beginning of 2017.

Thank you for your continued support of Hoyt Arboretum Friends.

At Hoyt Arboretum, every tree has a story to tell.

An arboretum is a promise to future generations. Just as we are enjoying mature and wonderful trees that were planted many years ago, the trees we plant today will grow to provide shade, beauty and value for decades and centuries to come. More than 6,000 specimens from around the world grow here, including more than 2,000 species, 63 of which are vulnerable or endangered. Hoyt Arboretum is a living laboratory where anyone can enjoy trees and plants that are both familiar and unexpected.
