Making a Difference

We offer previously incarcerated people a workplace where they can grow. We do it by offering mentoring, which helps with soft skills, and support by celebrating small wins. We believe that a supportive work environment that allows people to make mistakes so that we can use those mistakes as a learning lesson is key to helping people grow confident about their future.

At 42, we believe in bringing refreshment, not just to your home and business, but also to our community. Everyone has made mistakes.

We believe we are called to help bring a refreshing change in these individual's lives, which in turn bring positive impact to our local community.
