About SI of Three Rivers

Established in 2002, Soroptimist International of Three Rivers (SI3R) is part of a global volunteer organization that has advocated for women's empowerment since 1921.


We work to improve the lives of Mid-Columbia women and girls through programs that lead to social and economic empowerment. Our club is passionately involved in fundraising to provide educational assistance, programs for esteem-building, career coaching and mentoring, anti-human trafficking efforts and much more.


SI3R members love living in the Tri-Cities. We strive to be women of influence among our peers to better serve those in need throughout the community. We work hard together and we also have fun together. We balance our business activities with social gatherings for members to mingle and unwind.

We pledge allegiance to Soroptimist and to the ideals for which it stands:

The sincerity of friendship,

The joy of achievement,

The dignity of service,

The integrity of profession,

The love of country.

We will put forth our greatest efforts to promote, uphold and defend these ideals for a larger fellowship

in home, in society, in business, for country and for God.
