Thomas Lane
Thomas is Donna's trusted partner and co-trainer, bringing his own deep passion and expertise to the team.

“Dogs learn best in the environment they live in. In-home training eliminates distractions and ensures the skills stick — because we train where the behavior actually happens.”

What Dog Owners Are Saying
“Donna transformed our wild puppy into a well-behaved companion in just 4 sessions. Absolutely incredible! We had tried everything — online videos, group classes — nothing worked until we called The Dog Trainer LI.”
“Thomas worked with our rescue dog who had serious anxiety. The results were beyond what we hoped for. He has such patience and genuine love for dogs. Our boy is a completely different dog now — calm, happy, confident.”
“We've tried other trainers. Nobody comes close to the expertise and patience of The Dog Trainer LI team. They came to our home, worked with our entire family, and the results were immediate and lasting.”
