Thomas Leary is Global Sales Director and Business Partner at Baytech-HandMadeStone (HMS), a pioneering company transforming denim finishing with sustainable abrasive solutions. A Santa Monica native and UCLA graduate now based in France, he leads HMS’s global growth and strategic partnerships. HMS replaces traditional pumice stones with a patented, plastic-free alternative made with ZDHC-approved binders and upcycled pumice dust, maintaining the same aesthetic finish as pumice while eliminating its negative traits. Designed as a cost-saving, drop-in solution, HMS dramatically increases durability, reduces water use, and eliminates sludge—all without requiring new machinery. Mr. Leary’s work focuses on showing how sustainability can scale alongside performance, cost efficiency, and environmental responsibility in the global denim industry.
