Tiffani Crum, MS, DVM

Dr. Crum’s interest in animal behavior began long before attending veterinary school when she adopted her first dog from a puppy mill rescue organization.
She named her Sunny. Sunny was a timid, poorly socialized Bernese Mountain Dog who spent 3 years as a breeding dog. The special needs of this dog and her resilience are what really inspired Dr. Crum to become a veterinarian. While in veterinary school, she was VP of the Behavior Club and attended as many seminars as she could on Animal Behavior. Since graduating, she has focused much of her continuing education in this area. Dr. Crum is Fear Free and Low Stress Handling Certified. She is also a certified member of Family Paws, which is an organization dedicated to safely merging families with babies, toddlers, and dogs.

Dr. Crum currently sees behavior consults for both dogs and cats. After evaluation, she will discuss appropriate medications (when indicated), as well as design an individualized behavior modification plan to best help your pet.
