The History Of Thoroughbred Information Agency

Don Engel
Thoroughbred Information Agency (TIA) was founded in 1966 by the late California horseman Don Engel, a breeder who had purchased his first two broodmares in 1959. As with most creative pursuits, the inception of TIA began with a unique set of unpredictable circumstances.

While hauling a Thoroughbred mare one fateful day in 1966, Don stopped to fill his gas tank at a service station near Dixon, California, only to notice that his precious cargo — all 17 hands of her — had fallen down in a single stall of his two-horse trailer. Don panicked. How could he possibly get her back up to her feet without injuring herself, or him?

Suddenly, he remembered there was a Thoroughbred farm, Man Mar Ranch, nearby. Don drove there quickly, and was relieved when the farm owner, Manuel Jacinto, kindly helped him get the mare upright. Afterward, Manuel extended his courtesies to include a cup of coffee. As the two men chatted in the kitchen (something neither of them had envisioned they would be doing that day), Manuel mentioned he had just acquired a stallion named Slamruler, and casually asked if Don knew anyone who might help him advertise the new horse to California breeders.

A lightbulb went off above Don's head, and Thoroughbred Information Agency was born that very moment.

Thanks to Don's astute advertising efforts, Slamruler covered 66 mares — a very large book for the era — during his first breeding season at Man Mar Ranch. Other stallion owners took note of what Don was able to accomplish for the *Nasrullah sire, and soon they came calling too.

With his Thoroughbred Information Agency in full swing, Don initiated his "Confidential Report to Clients" in 1975. Twelve years later, that small publication evolved into "The TIA Newsletter," a popular resource which covered all Thoroughbred activities in the Western Region, with a specific focus on California, until 2007.

Among her other duties, Lisa also created and maintained TTA’s official website.
