About Our Trainers
Meet The Off Leash K9 Team
Devon Piatt graduated from Oklahoma State University and started her dog training career with Off Leash K9 Training in 2018. Since then, her love for dogs and helping families has only grown stronger. She believes that training isn’t just about obedience — it’s about creating a better bond and making life together more enjoyable.
Mark Piatt also graduated from Oklahoma State University with a degree in Applied Exercise Science. In 2020, he began training dogs and quickly found his passion in working with both dogs and their families. With his background in exercise science and years of coaching experience, Mark brings a hands-on, practical approach to training that focuses on structure, consistency, and communication.
Together, Mark and Devon are dedicated to helping dogs become well-mannered, confident, and reliable companions. At home, life is full with their two Border Collies and two kids, who all love being part of the adventure.
Allison Merritt - Program Coordinator
Allison Merritt is the Program Coordinator at Off Leash K9 Training San Antonio — and the first point of contact for most families who reach out. She’s the friendly voice who walks owners through the consultation process and helps match every dog with the program that truly fits their goals. And she gives that advice from real experience: before coordinating programs here, Allison spent 7 years as Head Trainer at the Off Leash K9 Training 30A location, training dogs hands-on every day. She supports both our San Antonio and Springfield locations, staying in touch from the very first phone call all the way to training day — and she loves helping families feel confident and excited about the plan for their dog.
Tanner Copeland - Trainer
Tanner Copeland has been training dogs with Off Leash K9 Training since 2020. His heart for this work is personal: after rehabilitating his own dogs, Tanner developed a special passion for the harder behavior cases — the dogs other people might be tempted to give up on. He knows firsthand that with patience, structure, and clear communication, even the toughest case can become a confident, well-mannered companion — and he brings that same belief to every dog and family he works with.
Geoff Iose & Casey Steinhauer - Trainers
Geoff Iose and Casey Steinhauer train side by side at Off Leash K9 Training San Antonio — and share life off the clock, too. Their Off Leash K9 journey began in California, where both of them trained at one of our California locations. After about a year there, they made Texas home, settling in Cibolo and joining the San Antonio team in 2021. Today they live in Cibolo with their son. Ask them why they love this work and the answer comes fast: there’s nothing like the moment a dog’s confidence clicks — and watching an owner’s face light up when they see what their dog can really do. Training as a team is what they do best: Geoff and Casey bring patience, structure, and clear communication to every dog they work with, and they love coaching owners just as much as training dogs. For them, it’s all about helping families enjoy life with a confident, well-mannered dog — on and off leash.
Cruz Salgado - Trainer
Cruz Salgado brings over a decade of coaching experience to Off Leash K9 Training San Antonio. Before training dogs, Cruz spent more than ten years as a personal trainer, helping clients reach their physical goals — and learning exactly how patience, consistency, and the right plan can change a life. His path to dog training started at home, working with his own dogs: rehabbing them so they could live better, fuller lives, without so much anxiety and fear. Watching that transformation lit a fire. Cruz realized the coaching he loved could change dogs’ lives — and their families’ lives — too, and he turned that passion into a career. Today he brings the same heart and discipline to every dog he trains.
