EDITOR AND GRAPHIC ART CONTRIBUTIONS:

I assisted professional tracker, Fernando Moreira with his book, Visual Mantracking back in 2016.  Fernando admitted the need to have his written work edited; as English is not his native language.  I graciously stepped in to help with the editing and book cover design.  I share some of his success, knowing that I helped make Visual Mantracking the best it could be.

My interest in tracking has increased through affiliations with combat/tactical trackers such as David Scott-Donelan, Ty Cunningham, David Everhart, Mic Bonin, and Troy Lettieri.
