A BIT ABOUT US

Bob Griffis - I have been collecting minerals for over 50 years, since I was 8 years old.  I have both B.Sc. and M.Sc. degrees in Geology, worked as a computer systems analyst, and have worked since 1989 as a corporate EHS manager.  I am published in the fields of igneous geology, geotechnical engineering, computer programming and computer applications in geology.  While work pays the bills, my first love is, and always has been, minerals - particularly from classic and unusual places.

Sarah Griffis - I began collecting minerals while in college, and have a special fondness for Sand Selenites and artistic specimens.  I have a B.Sc. degree in Geophysics, worked in the software industry, and published in the field of computer applications in geology.
