Originally founded in Watchung, New Jersey in 1994 as Whitestone Environmental Compliance Management, Inc., the company added geotechnical engineering and construction inspection capabilities in 1995 and subsequently was renamed Whitestone Associates, Inc. in 1999. Whitestone became a 100% employee-owned firm in 2021 when our Employee Stock Ownership Program (ESOP) was finalized.

Whitestone specializes in commercial, industrial, retail, multi-family and mixed-use site development/redevelopment from initial environmental and geotechnical due diligence investigations through site remediation and construction phase testing and inspection. Whitestone’s Property Condition Assessment & Facility Management group and Hazardous Building Materials Assessment & Management Services division provide a full range of building evaluation and consulting services geared toward existing facilities slated for continued occupation, repurposing, renovation and/or refinancing.

Branch offices in Chalfont, Pennsylvania (1999), Southborough, Massachusetts (2016), Rocky Hill, Connecticut (2017), Wall, New Jersey (2018), Philadelphia, Pennsylvania (2019), Tampa, Florida (2022), Bedford, New Hampshire (2022), West Palm Beach, Florida (2023) Rochester, New York (2023) and Buffalo, New York (2024) as well as satellite offices in Charleston, South Carolina (2015), Seattle, Washington (2020), Miami, Florida (2022) and Ridgewood, New Jersey (2023) were opened to accommodate Whitestone’s growth, expanding client base, and extended geographic range. Whitestone relocated to its current Warren, New Jersey corporate headquarters in 2020.

The company’s growth and continued success can be attributed to a simple “customer first” business philosophy and strict adherence to the firm’s Core Values of which the primary attribute is Quality. Whitestone’s zero-tolerance policy ensures the quality of our employees and our work product is of paramount importance. Additionally, Whitestone emphasizes its role as consultants, not just as engineers or scientists, and all employees are trained to “put yourself in the client’s shoes” – know what’s most important to the client, and ensure that the message is delivered in a way that’s easily received and readily understood.

Whitestone grew out of the recession of the early 1990’s, weathered the Great Recession from 2008 to 2013, and maintained operations through the COVID-19 pandemic. Our success is the product of maintaining our corporate focus, adhering to our Core Values, and ensuring an exemplary client experience. Yet, we’ve also retained a “corporate family” atmosphere and make certain we balance hard work with quality of life outside the office. Our corporate culture also embraces a “giving back and paying forward” philosophy that includes promoting charitable activities and volunteering opportunities.
