The husband and wife team Leonard and Lois Green co-own D. J. Stable. Green, a CPA and lecturer at Babson College, is a graduate of the Harvard Business School Owner/President Management Program. He holds a master’s degree in Taxation, with Honors, from New York University and an undergraduate degree in Accounting from Rutgers University. For almost 20 years, Green has taught Entrepreneurship and Family Business courses at Babson College. Green is also founder and chairman of New Jersey-based accounting and advisory firm “The Green Group.” The firm specializes in the Thoroughbred industry and has more than 700 equine-related clients, including many of the top-rated partnerships and syndications, as well as alliances with fellow owners and breeders, trainers, and jockeys.
During the 2020s, Leonard and Lois’ son, Jonathan, became more involved in horse ownership and took over management of the stable, and in 2025 the Green family found success at the highest level with the 3-year-old filly Nitrogen, who won graded stakes on dirt and turf and finished second against older females in the Longines Breeders’ Cup Distaff.
In her 4-year-old season, Nitrogen continued to excel, giving D. J. Stable their third Breeders’ Cup winner when she prevailed in the Longines Distaff at Keeneland.
