Cossentine Equestrian is a premier show jumping barn located in Portola Valley, CA, just off I-280 and centrally positioned on the Peninsula between San Francisco and San Jose. We serve riders from across the Bay Area who are looking for an exceptional, supportive, and personalized equestrian experience.

Led by Nessa Cossentine—a lifelong equestrian, professional show jumper, and microbiologist—our program is known for its positive, inclusive atmosphere and its ability to help riders of all levels thrive. Nessa is a patient and encouraging trainer who teaches every lesson herself, with experience supporting riders of all ages, backgrounds, and learning styles.

We offer tailored horse riding lessons designed to meet each rider’s goals—whether you're a first-time beginner, a returning adult rider, or a competitive rider aiming for national-level hunter and jumper shows. Our horses are carefully selected and matched to each rider, ranging from calm, caring, and experienced schoolmasters for those new to riding, to show-ready athletes for those looking to advance and compete. We believe the journey is just as important as the destination, and we pride ourselves on creating strong partnerships between horse and rider.

Our services include:
- Personalized riding lessons for all levels (hunter, jumper, dressage, equitation)
- Small group or one-on-one instruction
- Lesson horse, half and full lease opportunities
- Horse training and boarding
- Horse rehab program
- Schooling and rated show preparation and attendance
- Personalized horse purchasing assistance, including sourcing local and imported horses

Whether you're looking to start riding for the first time, return to a lifelong passion, or reach new levels in competition, Cossentine Equestrian is where riders and horses grow—together.
