I started mineral collecting right after I graduated from Earlham College in 2006 and two years later I earned my Masters of Art in Teaching at Earlham College in 2008. I fell in love with minerals when I took Mineralogy and the mineral specimen that took my breath away (and got me hooked) was this particular dioptase from Erik Louw's and Marshall Sussman's Collection, ( http://www.mindat.org/photo-18577.html ).

As I have gotten older, my focus on mineralogy has shifted, though I still have a collection of minerals from worldwide localities. My main focus are specimens from my home state of Ohio and minerals from the Illinois-Kentucky Fluorspar District. My favorite minerals are fluorite, celestine, and dioptase.

Besides collecting minerals, I also enjoy learning about historical information about mineral localities and try to share my knowledge that I have found on Mindat.

If you would like to use my photos, you have my permission to use them. All I ask for you in return is to properly cite the photos you will use. Thank you...

Finally, I also belong to the Cleveland Mineralogical Society. If you are interested in joining the club, go ahead and send me a private message!
