Ohio University B.S. Geology ’81, Queens University M.Sc. ’84
I am an Associate Vice President at the ARCADIS U.S. office in Wexford, PA, working as a Principal Geologist and Project Manager for soil, groundwater, sediment, and surface-water investigation and remediation projects, primarily located in the United States, as well as in Canada and Europe. I earned my B.S. degree from Ohio University in 1981 and my M.Sc. degree from Queens University in 1984. I toured the world for a year and began my career in 1985 at Integrated GeoSciences as a geologist/geophysicist exploring petroleum targets by electromagnetic methods in the northwest and central United States.
After returning for post-graduate studies in hydrogeology at Ohio University in 1986-1987, I began my environmental consulting career with Groundwater Technology in the Washington, D.C. area. From 1993 until 2000, I worked with Philip Services Corp. in the Pittsburgh area. I took a position with PTS from 2000-2001 and began my current position with BBL/ARCADIS in 2001.

I have managed projects that used the following remediation techniques: biologically based reductive dechlorination, geochemically based metals sequestration, groundwater containment and treatment, physical isolation using engineered barriers, physical state transformation/removal, direct physical removal, and monitored natural attenuation.
I serve as the primary liaison between my project team (including nationally recognized technical experts in a wide range of fields) and clients, regulatory representatives, legal representatives, and the public. In addition, I provided, and continue to provide litigation support through expert and factual witness testimony.
