Worked Under:4th Generation Horseman


I am a fourth generation horseman with a lifetime of experience with racehorses and the horseracing business. Starting with a pitchfork and a lead shank in my hand at age 5; I was galloping and breezing horses by age 9; and rode my first race at 12. I continued to ride horses professionally for 30 years; galloping for Hall of Fame trainer Mr. Richard Mandella as well as the San Luis Rey Division of the Hall of Fame trainer Mr. D.Wayne Lukas (under the direction of Mr. Chuck Karlin; nephew of Hall of Fame Trainer Mr. Jack Van Berg). While at SLRD I began forming my own racing stable and started my first horse at Hollywood Park in 1983. I have over 700 career starts and have won or placed in over 10 stakes races including the Grade I California Derby. I have won such races as the California Cup Juvenile and the California Equest International; and have set track records at Turf Paradise, Hollywood Park, as well as a track and World Record at Los Alamitos in 1992 which still stands today. I graduated in 1994 from Oklahoma State Horseshoeing School and I am a fully Certified Orthopedic/Therapeutic Farrier. I have completed a 2 year internship with Dr. Steven V. Colburn D.V.M. (official Veterinarian for the Vessels Stallion Farms); in addition to 2 semesters at the San Luis Rey Equine Hospital under the direction of owner Dr. Barry D. Grant D.V.M. while in graduate school working on my M.S. degree. After receiving my M.S. degree I began teaching as a professor and continued researching horses while pursuing my doctorate degree eventually serving as an Associate Dean. I have spent my entire life around racehorses, on top of racehorses, under racehorses; and inside of racehorses. I have studied and researched racehorses from the molecular level of neurotransmission of behavior, gaits and biomechanics of locomotion, and still further into the diet selection focusing on the horses neurological capabilities of diet selection culminating in the ability to self-medicate. Furthermore, I have studied and researched the environment and evolution that shaped the modern day horse; thus the phenotypical and genotypical changes that began 54 million years ago. I have dedicated and devoted my life to the horse. My lifetime of experience in the racehorse business, and my education, are both vast and very diverse. Please consider me as your trainer and let me put my experience and education to work for you and your racehorse(s). Please feel free to contact me at anytime.
