• I am a recognized thought leader in process safety — co-author of two CCPS publications that define the standard of care in process safety litigation and governance: Process Safety: Leadership from the Boardroom to the Front Line (Wiley/CCPS, 2019) and Guidelines for Process Safety in Outsourced Manufacturing, 2nd Edition (CCPS, 2026). When opposing counsel challenges the standard of care, my opinions carry the weight of the CCPS frameworks I helped author.
• My standard-of-care authority is grounded in 44 years of hands-on experience — 21 of them in direct operational roles including Plant Manager, Production Leader, and Site Director — running the chemical facilities where process safety is won or lost at the front line. That operational foundation distinguishes my analysis from purely academic or staff-function experts.
• At Dow Chemical (Fortune 50), across two positions I led the corporate initiative that achieved a cumulative 90% reduction in Tier 1 incidents over ten year...
