Our Firm

After 34 years as leaders in the engineering & environmental geophysical survey industry, Dorothy Richter, P.G., and Gene Simmons, Ph.D., P.G., have decided to shift gears slightly.  Now, we can share our life-long dedication to Geology & Geophysics by offering expert technical consulting services to engineering and design firms, government agencies, insurance companies, contractors, non-profits, and others.  We know how to be part of a team that works toward improving the technical quality of geological & geophysical investigations integral to large engineering & environmental projects for the benefit of the public good.

Yes, we are joining the gig economy, but then, so are all consultants.  And yes, this is a starter website so that friends, colleagues, and clients can find us as we get 



So please stay tuned, stay in touch, send us some gigs, and wish us well!
