She also works as a rabies collection officer for the OAVT Rabies Response Program.  In the summer months she enjoys getting outside hiking, camping and canoeing whereas in the winter she can be found watching YouTube videos and snuggling with her many pets. These include Jade, her Husky/Shepherd X, two orange and grey tabby cats Wiki and Zuko, and her Butter Ball python, Shade. So who are those two little puppies with her in the photo? Here's the story... She was volunteering for a week in a remote community in northern Ontario,  spaying/neutering for the community to help stop the animal culling practice there. That's where she met these adorable pups and their mummy. Her team ended up spaying/neutering just over 60 dogs and a dozen or so cats in 1 week! And they flew back to Toronto with three puppies who all found nice homes. 🙂

Tech Assistants

Cailey Chard

Erin Longo

BSc in Biological Sciences from University of Guelph (2017), currently working on MSc in Clinical Studies at UofG (current)

Since she was a little girl, Erin always loved animals. She grew up with a border collie rescue named Larry and her current family dog is another border collie rescue named Sadie. She also had a guinea pig named Butter and frequented the local rescues to say hi to all the animals! Since then she has worked and volunteered with rescue organizations and veterinary clinics in a variety of positions. During her university years, her love of animals continued through working in developed countries with veterinarians performing spay, neuter, and vaccine clinics to help countries with overpopulation issues. Soon after she found her passion when she ended up working with wildlife in rehabilitation centres. She was trained as a wildlife technician with the National Wildlife Centre and Hope For Wildlife, and she most recently worked to help Guelph wildlife with the Guelph Humane Society.  Erin is currently pursuing her MSc at the University of Guelph and joined us part-time to continue working with animals (puppy and kitten cuddles are needed to finish her MSc)!

Erin enjoys coming home to snuggle with her two cats Max and Millie while reading a good book or watching TV. Max is an ultimate cuddler and often likes to sit on her mom’s shoulders while she cooks. Millie is an ultimate lap cat and loves to nap, but she often gets the zoomies when anything with feathers is around, she will also do anything for a good treat. Erin loves to spend time in the outdoors to cycle, hike, and go to the beach!

Randi Speziale

BSc in Biological Sciences from University of Guelph (2020)

We are very pleased to have Randi join us full-time for the summer after spending many evenings volunteering her time at the clinic. As well as volunteering at Cornell, she has given her time at a variety of other clinics and kennels as well as the Humane Society in Thunder Bay. When she's not at school or volunteering, she enjoys travelling, reading books, and spending time at her home and cottage in Thunder Bay. As well, she likes hiking, walking and snuggling with her 6 yr old Golden Retriever named Nash. She also has a hamster named Thor.

She shares her home with an additional 'foster failure' feline, Mimaw, and is remembering her two beautiful dogs Karma and Gabriel that she sadly lost this past year.

Pat Sandford

Pat grew up in England where she loved to escape to the rolling hills, the moorland, or cliff paths beside the sea. Her favourite nature adventures invariably involved horses, cows, sheep, dogs and cats.
Years later in Canada, when her son went into grade one in 1989, Pat realized her dream of working in a veterinary hospital. She has been working in the veterinary profession ever since. Along the way she has cleaned kennels & floors, groomed dogs & cats, assisted in surgery, at the front desk and every other corner of the hospital! The part of working as a veterinary receptionist Pat enjoys most is being part of the beautiful relationship between pets and their people.
Pat has worked at several veterinary hospitals in Mississauga, including Park Animal Hospital where she worked as a receptionist for over 18 years.
When not behind the reception desk, Pat can be found in yoga studios (practising on her mat or singing), hiking in the woods with her camera, writing creatively and cuddling with her delightful kitty companion Penny. Sadly, Pat just lost her longtime feline companion Shanti, whom she misses greatly.

Hannah Taylor

Hannah comes to us from the great white north - Thunder Bay - where she grew up and also completed an HBSc in Biology at Lakehead University. She has over 4 years of experience working as a customer service representative at a range of vet hospitals. When not at work, she enjoys outdoor pursuits such as camping, hiking and running, as well as photography and crafting. Because of her partner's allergies she is unable to have a dog or cat of her own so she has a Leopard gecko named Kiwi, and she gives extra snuggles to all the dogs and cats that come into the clinic!
