Before founding CATCH, David led dog-training operations for a multi-location dog-care company in New York City. His work included training thousands of dogs, teaching group classes, coaching dog parents, developing training programs, and educating professional trainers.

Credentials describe David's training background; they do not imply veterinary licensure or review outside his professional scope.

Training approach

David's public work through CATCH emphasizes humane, reward-based training and practical education for both dogs and people. Leedo's public resources clearly separate training guidance from medical diagnosis and direct readers to a veterinarian or an appropriately qualified behavior professional when the situation requires it.
