Gregory is best known as the founder and former CEO of Mesmerize, a leading point-of-care and out-of-home media company serving healthcare providers, patients, and brands nationwide. During his tenure, he led the company's growth through strategic partnerships, acquisitions, and innovation, culminating in multiple strategic transactions and successful exits. Today, Gregory is the Founder and CEO of Cullet, a company focused on building the circular economy for glass through reuse, recycling, and localized processing infrastructure. In 2025, he led the acquisition of Repeat Glass to form Cullet Ohio, establishing the company's first operating platform and accelerating its buy-and-build growth strategy. A passionate advocate for sustainability and regenerative business models, Gregory combines decades of entrepreneurial experience with a commitment to creating environmental, community, and economic value. Through Cullet, he is working to modernize an antiquated glass system by keeping materials local, source-separated, and in circulation.
James Arnold is a recycling entrepreneur and sustainability advocate with more than a decade of experience building source separated glass recycling programs. In 2014, while earning his MBA, Jamie founded GlassBandit in Kansas City, helping pioneer community-based glass collection and recycling solutions.
In 2021, Jamie and his family returned to Cleveland, where he grew up. Before relocating, he successfully sold GlassBandit, combining the business with KC Crush Glass. The company continues to operate today as Crush Glass. Following his return to Northeast Ohio, Jamie recognized the need for a dedicated glass recycling system and launched Repeat Glass in 2022. Under his leadership, Repeat Glass grew into one of the region's leading source separated glass recycling programs. In February 2025, Cullet LLC acquired a majority interest in the assets of Repeat Glass to form Cullet Ohio LLC. Jamie stayed on as a partner, retaining a significant minority ownership interest, continuing to lead the company's growth and expansion efforts. Today, as Vice President of Business Development, Jamie focuses on expanding glass reuse and recycling infrastructure, developing strategic partnerships, growing community collection programs, and helping build a stronger circular economy for glass across Northeast Ohio.
Noel Pacheco helps ensure reliable collection service across Northeast Ohio. As a driver and part of the operations team, he works directly with customers and community partners to keep glass moving through the local circular economy.
