Business tip: Think outside the clinic. DNA testing doesn’t have to be sold in traditional spaces. Some of the most unexpected — yet high-traffic — places can become referral goldmines: strip clubs, pawn shops, tattoo parlors, barbershops, and even bail bond offices. These are places where real-life decisions are being made, emotions run high, and people need answers fast. Don’t be afraid to partner with businesses that serve the same communities you do — just in a different way. | Win with Barl
