Leandro is the assistant trainer and Doug's right-hand-man. He keeps the team together and oversees the daily workings of the operation, all while maintaining an incredible level of horsemanship. He does all of this, always with a smile on his face. A native of Mexico and now a U.S. citizen, Leandro began as a barn hand in 1977 under Gary Jones at Del Mar. He waited 35 years for a Kentucky Derby win, which he finally achieved in 2012 with I'll Have Another, and then again in 2016 with Nyquist.
Stephanie is Doug's assistant trainer based at San Luis Rey Training Center. A native Nebraskan, she began her career in racing as a groom. After a brief career as a jockey in the Midwest and East Coast, she relocated to California where she worked as an assistant to Kristin Mulhall and Peter Miller before going to work for Team O'Neill. One of Stephanie's favorite parts of her job is participating in the 2 year olds' growth and development as they prepare to head to the main track. She is married to rider Conor Murray and have a beautiful daughter who is a familiar face at the barn as well!
Dennis is the keen eye and ear behind Team O'Neill. He has an incredible eye for finding quality horses at reasonable price levels with potential to become world-class athletes (I'll Have Another and Goldencents to name two). A seasoned bloodstock professional, Dennis is always on the lookout for the best prospects and possesses an astonishing amount of knowledge of the game. Of course, like any brother worth his salt, he keeps Doug on his toes!
A lifelong fan of horse racing and a SoCal girl born and raised, Sharla wears many hats as she handles all of the daily management details that keep Team O'Neill running smoothly. In addition to assisting Doug, she oversees social media and marketing, obtains and works with corporate sponsors, handles administrative duties, coordinates vet visits, handles jockey club papers and name changes, among other responsibilities. She especially loves utilizing a network of farms, contacts and other supporters to place horses after they have been retired from racing.
