Discover the answers to the above questions during this basic financial workshop. You will learn how to manage money through simple changes and debt management plans. You will also learn how to make, grow, save, and protect your hard earned money using the basic principles for building a solid financial foundation that produces wealth.

Supporting Our Sisters International®

History & Mission

Supporting Our Sisters International (SOSI) founded by Madeline “MAD” Long-Gill, a survivorship organization was created to improve continuum care among African American and Hispanic breast cancer survivors. The goal of the organization is to help reduce breast cancer mortality for African Americans and Hispanics by focusing on health education for survivors.


Madeline established SOSI after many years of direct services as a training instructor for public assistance recipients, a homicide minister, domestic & sexual violence advocate, and a volunteer of 12 years with the St. Louis affiliate of Susan G. Komen Foundation. She served as President of Sisters Network Prince George’s County, an affiliate of Sisters Network Inc. These coupled experiences helped her understand the importance of health equity for all breast cancer survivors. Under her leadership, the awesome executive team of Sisters Network Prince George’s County reached over 10,000 people in less than 2 years through community health programs, workshops and medical screening participation. 


SOSI was created to support sisters worldwide with a message of health, hope, healing and quality care. Although the color pink represents breast cancer, SOSI has chosen to add a hint of green to denote living green aimed at helping women live healthier lifestyles to reduce their risk or recurrence of breast cancer.


SOSI has joined forces with survivors, family, friends, healthcare providers, researchers, community stakeholders, faith-based communities, and national organizations to create informative change within the breast cancer movement. SOSI believes we must support one another if we are to be the change. It will take all hands on deck to prevent and save lives!


Our mission: Through our exceptional attention to service, we are dedicated to saving lives by going beyond breast cancer awareness to empower, educate and inspire women around the world. We are committed to improving continuum care and services for the minority and under-served the community.
