On September 1, 2020, our founder, Will Johnson’s position as a Director of Internal Audit was eliminated due to the effects of COVID-19 on the parking industry. On September 28, 2020, (27 days later), J3 Audit Group, LLC (“J3”) was a legally registered entity with a mission to help clients who have parking revenue and operational control concerns. With a mindset of educating and providing expert resources “J3” leverages our expertise and other auditors in our network to support our clients. To bring our story full circle three months after the formation of “J3” our first client was the company who had to eliminate our founder’s position and they are still a client to this day. We value building relationships, educating our clients, and empowering our clients to meet and exceed their expectations.
