Owner Joe Cohen serves as CEO and principal consultant, holding CHFP (Certified Human Factors), CHCM (Certified Hazard Control Manager), and CXLT (Certified XL Tribometrist) designations, with advanced degrees from California State University, Northridge (MA, Applied-Experimental Psychology, Human Factors) and Alliant International University in San Diego (MS, Industrial-Organizational Psychology). The 92120 office provides expert witness testimony, accident investigation, and human factors analysis for litigation involving slip-and-fall injuries, vehicular collisions, construction-site incidents, and workplace exposures, and attorneys at firms including the Law Offices of Devon K. Roepcke, PC in San Carlos retain forensic specialists for case-specific analysis. The firm is the successor company to Cohen and Associates, a sole proprietorship formed in 1988 by H. Harvey Cohen, PhD, CPE, who previously co-owned Safety Sciences, Inc. (founded 1977) and served as a federal research scientist at NIOSH and as a post-doctoral research fellow at NASA. Joe Cohen has been qualified as an expert in Superior Courts across multiple California counties, Superior Court of Arizona (Maricopa County), District Court of Nevada (Clark County), United States District Court (District of Nevada), and the Intertribal Court of Southern California. The Waring Road suite sits in the Allied Gardens business district near the Interstate 8 interchange, and the firm's industry consulting arm handles workplace safety audits, ergonomic workspace evaluations, and program development for organizations in hospitality, transportation, manufacturing, healthcare, and construction — sectors where general contractors including Attic Construction in College Area manage jobsite conditions subject to OSHA and Cal/OSHA oversight. The practice draws on over three decades of casework spanning serious injuries and fatalities across industrial, residential, recreational, and commercial settings.
