Bridging Two Worlds
"Bridging the Gap Between the Natural Herd Dynamic and the Domesticated World"
Every horse lives in two worlds.
One is the world nature prepared them for.
The other is the world we ask them to live in.
Although domestication has changed where horses live, it has not changed who they are. Every horse continues to interpret life through the emotional, sensory, and social operating system that nature carefully shaped over millions of years.
My life's work is devoted to helping bridge those two worlds.
Not by asking horses to become less like horses, but by helping us better understand the remarkable animals they have always been.
Because I believe our responsibility is simple:
Helping humans understand horses as nature created them, so they can thrive in the world we've created for them.

Up Coming Event October 2nd-4th, 2026
Featuring Kerry M. Thomas with Featured In-Saddle Coach Sarah Welty
Sometimes the best opportunities are the ones you didn't expect.
A rare opening in Kerry M. Thomas's schedule immediately before departing for the Who Is The Horse? European Tour has created an opportunity to bring the immersive two-day Sensory Mapping Masterclass™ to Paswaters Acres in Fort Lupton, Colorado.
And because this is a true Colorado Pop-Up, this special pre-tour experience is being offered at a special Colorado Pop-Up rate for one weekend only.
Herd Wired: In Pursuit of Discovery
​
"Herd Wired is a foundational work on equine behavior and herd dynamics, exploring how horses process environment, pressure, and social structure at a neurological and emotional level. It is increasingly used as a reference by educators, professionals, and welfare-focused organizations seeking a deeper understanding of the horse beyond surface behavior."
A Field Companion for a Journey Through the Mind of the Horse
Step into the horse’s unseen world.
Decades of fieldwork—wild herds to elite athletes— distilled into a legacy you can hold in your hands.
Not a manual. Not a memoir.
An invitation.
​
“A literary field companion into the heart of the horse—
and the soul of connection. Herd Wired will change how you see your horse, your role,
and the emotional language between you.”
—Tegan Lush, 5★ Eventer, Australia
"Kerry nails it with this new book. Your horse has an operating system and "Herd Wired" is the owner's manual, a fascinating read for anyone who aspires to understand their equine friends from the hoofs up." Mark Coomes former Louisville Courier-Journal Turf Writer
"Herd Wired should be required reading for anyone who engages horses! Thanks for being an equine ally, Kerry!" Lissa Pohl ~ Equine Assisted Learning Expert

Reading the Horse, Reading the Ride. In conversation with Sarah Welty
Sometimes one conversation is all it takes to begin an entirely new chapter.
In this episode of Beyond the Hoof with Kerry and Daphne, we sit down with Sarah Welty—owner and trainer of Left Hand Ranch Equine in Fort Lupton, Colorado
For more than fourteen years, Sarah has worked as a natural horsemanship trainer, colt starter, and Mustang specialist. Her approach is grounded in understanding behavior, building trust, and creating clear communication between horse and rider.
We met Sarah and her family at the Wild Horse Symposium in Colorado. After watching part of her demonstration, something about the intention, feel, and communication Sarah brought to the saddle stayed with Kerry.
That chance meeting has now grown into an exciting new collaboration.
n this episode, we talk about:
• How Sarah found her way into working with horses
• What Mustangs have taught her about trust and communication
• The role intention and feel play in the saddle
• How we met at the Wild Horse Symposium
• What Kerry recognized in Sarah’s approach
• Why understanding both the horse and the ride matters
• The new partnership taking shape between Kerry and Sarah
• What listeners can expect from the upcoming Colorado Masterclass
Kerry reads and interprets the horse from the ground. Sarah brings the perspective from inside the ride. Together, they are creating a more complete way for students to see, feel, and understand the conversation taking place between horse and rider.
This Colorado event may be their first step together—but it could be the beginning of something much bigger.

"A horse lives by the laws of their nature. Where they fit in to the herd, how they interpret their world, how they learn, how they're coached, how they ultimately perform, is governed by the rules of that nature; it is wise to make an effort, to understand it."
