Colden Corporation is an independent health, safety, and environmental consulting firm founded in 1996 in Philadelphia. It partners with organisations in the United States and abroad to deliver practical, tailored EHS solutions, working across industrial hygiene, occupational safety and environmental health and safety. The firm operates seven offices in key markets nationwide and counts Fortune 100 companies among its clients.
The company is owned and managed by practising Certified Industrial Hygienists (CIHs) and Certified Safety Professionals (CSPs), and professional certification is central to its technical work. Its founders, David de Lalla, Greg Richey and Chris Wesley, remain actively involved in the business. Staff work directly with clients on health and safety programmes, and the firm emphasises quality, continuous learning and responsive service.
Colden describes itself as people-centred and practical in its approach, with solutions shaped to the needs of individual clients rather than standardised offerings. Its stated values are Experience, Integrity and Service. The name is drawn from Mount Colden in New York's Adirondack Mountains, chosen to symbolise strength and resilience.
