Meet the Team
Wilbur
Dogtor of Veterinary Medicine
Dogtor Wilbur has been living and breathing rehab since he was just a pup. He spent months of his puppyhood with a splinted leg, then worked his way through physical rehabilitation to regain the strength and flexibility he had lost. These days, he strictly manages the CROC team, ensuring the high level of medical care our patients deserve. He frequently sacrifices his time and dignity to personally test all equipment, exercises, and treatments to make sure they meet his expectations for patient experience. His favorite part of rehab is meeting new patients that need a little confidence boost and helping them take on new challenges. In his free time, Dogtor Wilbur enjoys whipping human legs with his incessant tail wags, visiting the pet stores to get free cookies, and sunbathing.
