Guided by FAITH, FAMILY, AND A PASSION FOR SERVING OTHERS, the 4R Foundation was established to advance the ministry and donation efforts of the 4R Restaurant Group. In 2004, John Rivers harnessed his passion for cooking to serve the community in the greatest way possible. His will to serve others led him to host a cookout fundraiser in support of a young girl who was battling cancer. Recognizing the impact his cooking could have on those around him, he embarked on what came to be known as the “barbecue ministry.” John, along with friends, family, and a growing team of volunteers, cooked for anyone that needed help – schools, churches, charities, civic organizations, and people in distress.

Over the years, the "barbecue ministry’s" popularity grew until John could no longer handle the operation from his garage. Pledging to preserve the values of the ministry, he opened his first restaurant, 4 Rivers Smokehouse, in 2009. From those modest beginnings, 4 Rivers has expanded to twelve locations throughout Florida. Throughout the years, 4 Rivers and its employees have maintained a focus on community support.  As of 2016, 4 Rivers has contributed over $2,000,000 in charitable donations to organizations and individuals in need. In 2015, the 4R Restaurant Group established the nonprofit 4R Foundation to ensure the continuation and enhancement of its charitable efforts.
