In the fall of 2018, Hallstar reorganized its global organization into two distinct divisions – beauty and industrial – to better focus on market-specific industry solutions and support its customers. The company created two new division president positions, while John J. Paro remained chairman and CEO.
Masciantonio came to Hallstar in 2001 with the acquisition of RTD Chemical where he had worked since 1995. Starting as a business director for Hallstar personal care ingredients, he added sourcing and purchasing responsibilities over the years and, in 2013, was named vice president, supply chain, and general manager for all product lines, successfully leveraging the synergy between product management and sourcing. From 2016 to 2018, Masciantonio served as the North America region vice president responsible for all P&L operations, sales and sourcing in the NA territory.
