My personal philosophy is that the work I do should result in environmental sustainability, social sustainability and my client’s business sustainability. Without all three, continuing environmental improvement can’t be accomplished.
Over the decade of the 2010’s, I taught many thousands of regulators, consultants, owners and other stakeholders about science-based petroleum hydrocarbon LNAPL assessment and remediation guidance that I helped write and revise as part of teams organized by the Interstate Technology & Regulatory Council (ITRC).
I help our Oil & Gas clients by providing strategic direction for their contaminated soil and groundwater sites, advocating for that strategic direction by engaging regulators and other stakeholders in a science based dialog, and backing up the strategic direction with practical knowledge of how to evaluate and demonstrate remedial effectiveness.
My most rewarding Oil & Gas project was remediation of an 18-acre fuel release and the associated mile-and-a-half long MTBE plume that was cleaned up to MCLs in an expedited timeframe to meet regulatory orders and other stakeholder interests. Because of the high bar set for this project, remedy design, implementation, and performance were all carefully and thoroughly evaluated by a team of national and international experts. As a result, I gained in-depth knowledge, perspective and insight that has allowed me to both teach and bring to many other projects a clear-eyed, science-based approach to petroleum hydrocarbon remediation.
The thing I enjoy most about my job is providing the science-driven solution to client’s environmental challenges that balances reducing the business risk of environmental liabilities with clearly achievable remedial goals. At every site, the balance between the liability owner’s business drivers, regulatory framework, cleanup levels, and cleanup timeframe, as well as contaminant hydrogeology, is a unique combination of commonly used and innovative approaches.
My most important professional accomplishment is working on the ITRC LNAPL team to change how US States, and other countries, regulate cleanup of Oil & Gas sites so that they promote better results.

I am an avid cyclist and enjoy riding everything from narrow trails to fire and gravel roads to smooth ribbons of asphalt.
