I am here to help you use geology to make informed decisions

I can bring over 40 years of experience to your business.

My Philosophy

I started my career with the US Geological Survey (USGS) as part of a project that had two main goals; (1) to figure out how to apply geology to real life situations, and (2) to communicate those results to the appropriate users. I carried those goals with me throughout my 41-year career with the USGS.

I was the USGS Aggregate Geologist from 1976 until my retirement. My current business builds on the knowledge I gained with the USGS, and I now specialize in aggregate resources (sand, gravel, and crushed stone) and other industrial minerals.

As a Research Geologist, I utilize the scientific method to acquire geologic knowledge and arrive at conclusions about the world around us. The scientific method is conducted in an objective manner and tends to produce unbiased results.

Regarding aggregates and other industrial minerals, those results can be used:

  • During the permitting, land-use planning, and resource protection process to facilitate informed land use and resource management decisions.
  • For the selection of mining and processing methods to maximize production efficiency and minimize environmental impacts; and
  • For planning and implementing the reclamation of mined-out areas.
