John Charles Martin, rancher, businessman, mentor and friend to countless people passed away November 6, 2012, at St. Mary's Hospital in Grand Junction. He was 68 years old.John was born August 2, 1944, in Grand Junction to Richard and Wilma (Billie) Martin and spent his younger years in the Grand Valley. In 1952 the family moved to Carbondale, where John remained until his death. John graduated from Carbondale High School in 1962 and developed his mechanical skills at a diesel school in Utah.John married Marilyn Trump in 1972 and they had two children, Sean and Holly. John and Marilyn spent nearly 25 years together before divorcing. John went on to marry Laura King and spent the last twenty years of his life with her. With that union he also welcomed Laura's children into his life: John, Katie and Zane.John was known to all as a man with diverse interests. He was exceptionally passionate about work and spent many years building his businesses. Through the years John was involved in ranching, sand & gravel production, ready-mix concrete, real estate development, and restaurant ownership, among many other fields. John loved to take on a challenge and was an excellent source of business advice. He thrived on making big deals and was at his best in high pressure situations. He was also a man who was always ready to listen when a person had a problem, and genuinely wanted everyone he knew to be successful and happy in what they were doing. John's generosity and compassion were cornerstones of his personality.When he wasn't working (which was rare), John enjoyed snowmobiling, jeeping and collecting antiques that he found on eBay or in little, out of the way stores. He had a fantastic sense of humor and liked to work South Park references into conversation. He loved animals and being outdoors and combined the two whenever he could. John rarely went anywhere without his buddy, Kelpie Grande`.John is survived by his wife, Laura Martin; children Sean and Holly (Robert) Martin; step-children Jon (Erin) Willis, Zane (Charlea) Hubbard, and Katie (Shelly) Willis; siblings Bill (Helga) Martin and Jimmie (Dan) Downer, as well as several grandchildren, nieces and nephews.Following a private burial, the family would like to invite all who knew John to attend a celebration of life gathering Wednesday, November 14, at 11:00 A.M. at the Tybar Ranch, 100 Angus Lane, outside of Carbondale. In lieu of flowers, we request that those who wish to honor John's memory do so with a contribution to the American Diabetes Association.
