Josh Colman
As a young boy I was always interested in mechanical objects and item's that could be disassembled and put back together. I had built bicycles to minibikes before I was twelve. I had schooling in drafting (cad cam) but had become bored once I had a job doing this.
I took a part time position in a local dealership (GM & Toyota) in the parts deptartment. I spent eleven years there until leaving to further my horizon's at Mathewson's, which I have been with for thirteen years.
I have recieved schooling and certification in automotive management operations, various customer handlings, GM and Toyota parts management and general automotive repairs. I have always enjoyed this industry and found it to be very rewarding.
Outside of Mathewson's I enjoy many outdoor activities, sports, family and of course I'm involved with cars and events.
