Simon was born and raised in Marathon, Texas by Juan and Gabina Villa. He attended school in Marathon and was a ranch hand for many years in the Marathon area, working for several ranches as a young cowboy. His passion as a young boy was to ride bareback broncs. His love for the ranch and cowboy life was evident by his love for country living.
