Make a Donation

Each year, SI3R gives more than $15,000 back to the community in the form of scholarships, supporting mission-based programming, and implementing projects designed to improve the lives of women and girls. Your donation, no matter the size, helps us achieve our service goals.  SI3R is a 501(c)3 organization; therefore, your donations are tax deductible. If you would like to donate, please send a check to:


Soroptimist International of Three Rivers

P.O. Box 1097

Richland, WA 99352 

If you would like your donation to be applied to a specific project or initiative (e.g. Live Your Dream Award, Women's Opportunity Awards, STOP Trafficking), please specify this in the memo section of your check. 

Attend a Fundraiser 

Our fundraisers are a great mix of fun and philanthropy. Each year, we hold a holiday dinner/auction that is sure to delight you and your friends. Over the course of a fabulous dinner, you have the opportunity to bid on baskets containing local and regional goodies. All proceeds from this event go towards funding our service projects throughout the year. Similarly, in the spring, we hold a winemaker's dinner where you can enjoy Mid-Columbia's finest wines and bid on mystery wines while contributing to our worthy causes. Stay tuned throughout the year to see how you can participate in these events.

Volunteer Your Goods/Venue

A lot of hard work goes into coordinating our fundraisers and community events. We often call upon the community to help us with donated goods such as wine, gift cards, food, and other materials. We also appreciate your partnership in helping to house our events and meetings. If you'd like to volunteer your space or specialty items, we would be very appreciative. To discuss this in more detail with us, please contact us at sithreerivers@soroptimist.net.

Spread the Word

Our greatest allies in this community are the people who speak highly of our organization. We are on a mission to grow our club so that we can help more women and girls. Your words have power, so use them to empower others! Tell your friends about the good work that we do, invite them to visit this website, or request more information from us to post up around the community. We appreciate all of your support and goodwill.
