Message from President and Co-Founder

Thanks for stopping by our site! We started Breast Cancer Hawaii as a website back in 2016 to help reduce the information overwhelm that we experienced as patients navigating our own breast cancer diagnosis. Since then, we've expanded our programs based on the needs of the local breast cancer community. Today, we operate as a 100% volunteer-run nonprofit startup. 

You can find more details of our programs below, as well as profiles of our team members. We're continuously listening to feedback from local patients and survivors. If you have suggestions for us, we'd love to hear from you! Feel free to reach out to us at 808.215.0303 or
