Developing horses and riders for the world stage.
Decades of horsemanship, coaching, and results — from junior championships to a 5* Grand Prix podium, the Paris Olympic Games, the World Equestrian Games, and the European Championships.
For over two decades, I've developed horses and riders at the top of the sport — from junior championships to CSI5* Grand Prix podiums, the Paris Olympic Games, the World Championships, and the European Championships.
I'm a third-generation horseman: my grandmother founded Evergreen Equestrian in the early 1960s, and I worked for years under Norman Dello Joio, individual bronze medalist at the 1992 Barcelona Olympics. Since 2016, coaching has been the work — not a sideline, but the profession I've built everything around.
With Harrie Smolders and Chris Sorensen, I co-founded M.70 — a coaching and athlete management company where every rider trains directly with all three principal coaches. Alongside it I run Du Val Soleil, breeding from proven 1.60m Grand Prix damlines, and Evergreen Equestrian, sourcing and matching horses at the highest level.
I split my time between our bases in Europe and Wellington, Florida — an operation built so athletes can train, compete, and develop from either side of the Atlantic.
A bespoke coaching and management company for show jumping athletes, co-founded by Sean Crooks, Harrie Smolders, and Chris Sorensen. Riders train directly with three championship-level coaches — not assistants — for individually focused development built on data-driven methods and traditional horsemanship.
Breeding · Sport · Excellence. A deliberately small program producing performance sport horses from proven Grand Prix damlines — quality over volume, every year.
We source and produce horses to the highest levels of the sport, then pair them with the right people — matchmaking built on decades of knowing exactly what a horse can become, and exactly what a rider needs.
