In recent years, he has launched B2B partnerships in 25 US states, payor agreements, collaborations with manufacturers, and hospital discharge initiatives. Ben was also able to codify process with sales-achieving industry-leading referral conversion rates while simultaneously driving B2B utilization and unit economics.
