Josh provided seed capital to Kris Krane to form 4Front Advisors in 2011 and joined as a full-time team member in 2014 when 4Front began to explore opportunities beyond consulting. Previously, he spent 13 years as an equity analyst and portfolio manager in the financial services industry, during which time he became one of the youngest vice presidents in Credit Suisse’s history. Josh moved into private equity in 2008 because he wanted to have a more meaningful impact on companies.

As an electrical engineer, Scott spent twelve years designing and managing the implementation of military base security systems in eight countries and thirteen states. The desire to put his talent and energy into a different kind of global effort, one which has the potential to heal millions and make the world a better place, drew him away from a comfortable career and toward the emerging, chaotic world of cannabis.
