Copy: In 2004, John Rivers channeled his will to serve others into a cooking fundraiser to support a young girl battling cancer. Recognizing the impact his cooking had on his community, John, along with friends, family and a growing team of volunteers, decided to continue the barbecue ministry for any person or cause that needed support–schools, churches, charities, civic organizations and anyone in distress. Over the years, it outgrew John’s garage, and in 2009 he opened his first restaurant, 4 Rivers Smokehouse, with a pledge to preserve the barbecue ministry’s values. Since then, 4 Rivers has expanded its focus on community support to 14 locations throughout Florida and one in Georgia.

In 2015, the 4R Restaurant Group established the nonprofit 4R Foundation to ensure the continuation and enhancement of its

charitable efforts. We are proud to host and participate in events that bring awareness and support to impactful issues benefitting their respective charities, such as Cows ‘N Cabs in Winter Park, Florida, as well as its sister event, Pink & Swine, in Tallahassee, Florida. Apart from fundraising events and community gatherings, we continue to serve others by welcoming informal requests for grant distributions for child development and education, critical needs and social services, and catastrophic injuries and illnesses. Our latest initiative is The 4Roots Farm, which is dedicated to fostering a healthier and more economically vibrant regional food system. John believes in the power of collaborating, educating and empowering positive change through the nourishment of and access to a local food network. In the end, we will build a better future for our children and generations to come.
