Doc O'Lena was foaled in 1967, sired by Doc Bar and out of the mare Poco Lena. He is one of only two horses in the American Quarter Horse Hall of Fame with both parents also inductees; the other is Easy Jet. His color was bay, and his only markings were a small star on his head, and a small white half pastern on his left hind foot. He was bred and owned by Dr. and Mrs. Stephen F. Jensen of Paicines, California at the time of registration.
Career
The Jensens had hoped to sell Doc O'Lena as a yearling to cutting horse trainer, Don Dodge. Dodge had purchased Doc O'Lena's dam in 1953 from E. Paul Waggoner’s Three D Stock Farm in Arlinton, TX., and had successfully shown her to win numerous AQHA and NCHA awards and titles. After seeing Doc O'Lena, Dodge concluded that he was too small to be a cutting horse, and passed on the offer. The Jensens decided to keep Doc O'Lena and get him into the hands of a professional trainer. They contacted Shorty Freeman who, in 1968, was hauling for the NCHA World Championship title showing King Skeet for Adrian Berryhill. On his way to the San FranciscoCow Palace, Freeman stopped by the Jensen's to look at Doc O'Lena. Freeman wasn't concerned about the yearling's small size, and agreed to take him for training. During an interview, Freeman recalled the first time he tried to ride Doc O'Lena as a green broke, long yearling and the colt ran off with him. He said, "I didn't think running off belonged to him, so that didn't really bother me." Referencing Poco Lena he said, "Besides, I knew what the old mare was, so I wanted to ride him." He also said, "I didn't train Doc O'Lena anyway, he trained himself. I knew about 30 days after I got him that he was an exceptional horse... I always had to ride him last in the training program, 'cause if I didn't, I'd be mad at all the other horses in the barn. He was just that good." In April 1970, Adrian Berryhill partnered with Freeman and they purchased Doc O'Lena from the Jensens for $15,000. In December that same year, Freeman rode Doc O'Lena to win the NCHA Futurity, and "became the first competitors to make a clean sweep of the futurity’s preliminary go-rounds, semi-finals and finals", winning $17,357 for his new owners. Doc O'Lena's NCHA lifetime earnings totaled $21,991.93, and he had also earned an NCHA Certificate of Ability.
