Legacy Giving
Endowment
The Grande Ronde Symphony Association (GRSA) is proud to announce the establishment of the “Grande Ronde Symphony Fund” endowment managed through the Oregon Community Foundation’s Endowment Partners Program. Our fund will continue to grow over time, preserving and enhancing its value for the Grande Ronde Symphony’s future needs.


“The Grande Ronde Symphony has been filling this Valley with music for over 75 years. As they celebrate this history, the Grande Ronde Symphony Association is also looking toward and planning for the future. We hope our gift to the Grande Ronde Symphony Fund Endowment will encourage others to give and ultimately grow the fund to sustain the symphony for generations to come.”
– Dale and Ginny Mammen
Enriching lives through the power of music!
Our new endowment was initially funded by an incredibly generous donation of $50,000 from Dale and Ginny Mammen. Their confidence in the Oregon Community Foundation, along with the Grande Ronde Symphony Association, prompted the Mammen’s to make a challenge to other potential contributors to match their $50,000 contribution during the 2024/2025 concert season.
We are delighted to report that the challenge was met by contributions to the Grande Ronde Symphony Endowment by the following:
Andante Circle Members ($10,000+)
Dale and Ginny Mammen
Robert Delve
Earl and Lisa Davis
Anonymous Donor
Meredith and Jack Wilson
Allegro Members ($5000)
Matt Cooper & Sharon Porter
What a tremendous commitment to the future of the Grande Ronde Symphony this giving has created and we are so grateful to these generous friends!
This is only the beginning of helping the organization towards long term sustainability that would allow us to have security annually without reliance on grant funding, ticket sales, annual patronage and corporate sponsorships.
