Meet Our Team

  • Dr.

    Dr. Scott Stevenson originally joined the TIVS team as an Externship Student and that evolved into him becoming one of our veterinarians and eventually he took over ownership of the clinic from Dr. Willows. Scott is originally from Barrie, Ontario, but fell in love with the Gananoque area while investigating blacklegged ticks and Lyme disease in the Thousand Islands during veterinary school. He carries this passion with him today, regularly speaking to veterinarians and clinic staff across Ontario about expanding tick populations and the increasing threat of tick-borne illnesses to both pets and humans. Scott’s goal is to be the person that all current and new clients of TIVS seek out to answer all questions related to ticks in eastern Ontario!

    Scott was first inspired to pursue veterinary medicine when his family dog, Katie, a cocker spaniel, experienced a gall bladder rupture and spent time at the Ontario Veterinary College’s teaching hospital. He was fascinated by how the veterinary team was able to improve Katie’s health while also strengthening the bond his family had with both Katie and the veterinary team.

    He has a special interest in emerging technologies, particularly in how new technology can help build a stronger relationship between the veterinary team and the patient’s family. He considers himself incredibly lucky to have spent time working with LifeLearn in Guelph, Ontario, training Sofie - the first cognitive computing solution in veterinary medicine, powered by IBM Watson.

    Scott lives with his wife, Lisa, their sons James, Everett and Tyler and their cat, Raven. In his spare time, Scott enjoys playing golf, and is looking forward to once again competing in provincial amateur championships and local invitational tournaments. He also enjoys back country camping and canoeing, hiking, playing hockey and snowboarding.

  • Dr.

    Dr. Monika Janssen joined us in November of 2020 and is a 2013 graduate from Guelph’s Ontario Veterinary College. She was actually classmates and surgery partners with Dr. Stevenson in school! She and her husband have a 2 year old daughter named Evelyn and a 7 year old Akita named Kuma. Monika loves all pets and aspects of being a Veterinarian, but she has particular interest in dermatology, ultrasonography and small mammal medicine (bunnies, and pocket pets).

    In her spare time Monika loves hiking, beach volleyball, camping, cuddling puppies and kittens and collecting books that she may or may not find the time to read!

    You’ll often find Monika on the floor giving love to her patients before and after their exams. Her enthusiasm, sense of humour and her genuine care and compassion for all animals have made her popular with our patients, clients and staff alike! 

  • Dr.

    Dr. Stephanie Gerritsen is a 2019 graduate of the Ontario Veterinary College and is the newest addition to the TIVS team! Stephanie is originally from Whitby, ON and found her love of veterinary medicine through her numerous pets and frequent trips to the Toronto Zoo growing up. Once she graduated from the Ontario Veterinary College, Stephanie spent a year practicing emergency medicine in Peterborough, ON before carrying on to general practice working with dogs, cats, and exotic animals in Cambridge, ON. 

     Stephanie has a special interest in the care of all animals, from fur to feathers to scales! She is a current member of the Association of Exotic Mammal Veterinarians, the Association of Avian Veterinarians, and the Association of Reptile and Amphibian Veterinarians on top of her time working with dogs and cats. While she loves all the animals that come through the door, she has an extra soft spot for falcons, hawks, and other raptors as she was lucky enough to work with these beautiful birds the past few years. 

     Stephanie lives with her fiance, Dan, and a sassy senior tuxedo cat named Stella. In her downtime Stephanie loves to explore hiking trails and camp in the woods as well as crochet amigurumi and sketch. 

     Dr. Stephanie is excited to be joining the team and is looking forward to taking the best care of your beloved dog, cat, rabbit, guinea pig, hedgehog, lizard, snake or bird!

    Outside of work Mandy loves to do what she calls ‘Granny Crafts’ like crocheting and quilting. She also enjoys acrylic paint pouring and paint nights. She also loves camping and hiking with her dogs.

    The joke at work is that Mandy especially loves the ‘squishy faced’ critters. This is evidenced by her two dogs.

She also lives with her 2 (much loved) domestic shorthaired kitties named Poppie and Little Em.
