A partnership of the Americas
Vladi Rivkin
Vladi Rivkin grew up in Palo Alto in the San Francisco Bay Area where he discovered his passion for polo at the Menlo Circus Club. His competitive drive soon brought him north to Marin and Sonoma, where, in 2015, he founded the Horses and Horsepower Polo Tournament and launched PoloSF, a full-service polo lease horse operation. In 2020, Vladi established Stone Tree Ranch and began developing Napa Valley’s first arena and field polo club, based in Calistoga. Today, his operations extend from his own polo club in Calistoga, the home of Stone Tree Ranch, to Wine Country Polo Club where he competes and provides lease horses, to Pilar, Argentina, in partnership with professional player Manuel Crespo. A member of the Federation of International Polo, Vladi also organizes international polo trips and tournaments in collaboration with fellow FIP clubs.
