About Us

Using the latest in data modeling and machine learning techniques, Performance Genetics is the only company that utilizes DNA markers, cardiovascular and biomechanical measurements in a single prediction model to make selection of champion racehorses as accurate as possible.


While this is a scientific endeavor that is driven by the data we collect, we also place an emphasis on using our horsemanship and experience in the thoroughbred industry to achieve a balance between the science and practical horse knowledge and horsemanship.

Please feel free to take a look at our success stories as well as our informative blog and contact us should you have any questions
