Mission & Vision

We are chemotherapy angels who provide motivational and financial assistance to women living with triple-negative breast cancer.

Our organization focuses on triple-negative breast cancer because there is no targeted treatment for it—yet. As we strive to lessen the burden on women who receive this diagnosis, we also aim to find a targeted treatment for TNBC. Our individual assistance is tailored to each woman’s situation and needs, and everyone we support becomes part of our loving TaTa Sisterhood.

Funding Research into TNBC Treatment

In addition to helping those with TNBC stay hopeful and strong, we are actively fundraising to support promising research in breast cancers diagnosed as triple-negative. In TNBC, none of the three targets for treatment of other breast cancers are present. Although traditional chemotherapy is an option to help fight the disease, these and other specialized hormone therapies are often not as effective.

Help us build a future where women with TNBC will have new and powerful treatments to support their healing.

“Make the most of every day.Make every day count.”

- Tara Boland, Founder

Our History

The TaTa Sisterhood Foundation was founded in 2013 and has supported more than 300 women with TNBC.

Our work has been powered by dozens of volunteers and hundreds of donors, building on the vision of our founder, Tara Boland, and her loving friends who came together to bring the TaTa Sisterhood to life.

Our Events

Whether we’re reveling in “MargariTa-Taville,” meeting up with other TNBC fighters for a Sisterhood brunch, or raising funds at an epic Wiffleball tournament, we make opportunities to gather all year long.
