Outstanding craftsmanhip shown on his models has earned him numerous awards plus widespread appreciation and respect.


His hobby is now his profession. Drawing upon his modeling success, John has expanded into new fields, offering consulting services, instructing, seminars, exhibitions, as well as continuing to teach modeling theory and practice to the younger generation interested in this work.
