  • Dr. Wendy Robertson, DVM

    Dr. Wendy Robertson, an associate small animal veterinarian at Trumbull Animal Hospital,
    already knew as a ten-year-old growing up in Ridgefield, CT, that being a vet was her dream.
    That’s the year she became involved with the local dog shelter and a non-profit cat rescue
    organization. From her volunteer work there with homeless dogs and cats, her true passion and
    desire to become a veterinarian sprang.
    Early on her mother warned her that veterinary medicine is not an easy job of “playing with
    kittens and puppies all day.” Taking hold of that challenge, Dr. Robertson found a local
    veterinarian who allowed her to volunteer in his practice at the age of 14. She has worked in
    small animal veterinary practice ever since.
    After her growing up years in Ridgefield, Dr. Robertson moved to Virginia during high school
    followed by undergraduate studies in microbiology at Virginia Polytechnic Institute and State
    University (VA Tech). A standout student with, by then, multiple years of experience working in
    veterinary clinics, Dr. Robertson was one of an elite group of students admitted to the
    Virginia-Maryland Regional College of Veterinary Medicine in Blacksburg, VA, after only her
    sophomore year. She was awarded her Doctor of Veterinary Medicine in 1995.
    Initially after obtaining her DVM, Dr. Robertson practiced primarily equine medicine in
    southwestern Virginia. In 2000, family circumstances brought Dr. Robertson home to
    Connecticut and back to small animal medicine.
    After working in both small animal general practice and small animal emergency medicine, Dr.
    Robertson found her home at Trumbull Animal Hospital in 2008. Dr. Robertson’s professional
    interests include small animal internal medicine particularly cardiology and endocrinology,
    geriatric medicine, pain management and feline medicine.
    When not working at Trumbull Animal Hospital, Dr. Robertson enjoys spending time with her
    husband, Darryl, daughter, Emily, their dog (Bailey), four cats (Isabelle, Gracie, Chloe and
    Simba) as well as nine fire-bellied toads (Spotty Dot, Croak, Toad, Hop, Sally, Plunk, Chunk,
    Dude and Murray). Bailey is often seen during her time filling in as a receptionist at Trumbull
    Animal Hospital.
    With 13 marathons and an ultra (Bimbler’s 50K 2018) under her belt, Dr. Robertson is an active
    runner, equestrian and outdoor enthusiast often frequenting the Trumbull Rail Trail.
