Lesley Vanclief, Office Manager/Veterinary Assistant

Lesley graduated from Durham College as a Veterinary Assistant in 2006 and before that earned her Equine Diploma from The University of Guelph. Lesley has been with us since 2012 and enjoys meeting new clients and maintaining a close professional relationship with all of our existing clients and their fur babies. She shares her empathy and love for all animals when it comes to dealing with our clients and makes it her mission for you to leave the clinic knowing you have received the best care for your pet.

When not in the office, you can find Lesley at her farm with a plethora of four legged animals, which include her two dogs, four cats and somewhere in there some fish, horses and a donkey! She has a passion for cooking, gardening, camping, horseback riding and kayaking, which she enjoys doing with her two children and her friends.

Halie Sproul, RVT

Hi, my name is Halie and I started at WOAH Fall 2023. I am an RVT who graduated from Seneca College in 2023. My favourite part of the job is meeting all the different furry friends who walk through the door. I am originally from Nova Scotia and have a Bachelor of Arts majoring in History and a Postgraduate Degree in Museum Management. I made the move to Ontario permanently in 2019 to explore a new career with animals. I love all things horses, large animals, Exotics and wildlife. In the future I hope to be a zoo RVT!

In my spare time I enjoy playing video games and spending time with my many pets. I have 1 dog, 2.5 cats, 3 snakes, 1 gecko and a horse.

Grace Janes, RVT

Grace Janes is a graduate of the veterinary technician program at Georgian College.  Her favourite part of the job is knowing she is helping your furry family members stay happy and healthy. She started as a receptionist in a vet hospital and was inspired to learn more and do more by becoming a technician. She has 2 dogs and 2 cats in her family and hopes to add more to the pack in the next year. Her other hobbies include drawing, cooking, hiking, and photography (mostly of her pets).

Aleashia Humphries, Office Manager/Veterinary Assistant

Aleashia came to White Oaks in 2013 to gather hours to apply to Veterinary College. She volunteered every summer and we liked her so much, we asked her to become a team member in September 2017. Aleashia’s love of animals comes from always having a house full of fuzzy feet. Her family enjoys fostering animals that wouldn’t have been given a second chance. These fosters usually have a medical condition that requires constant care. Her current foster Milo has cerebellar hypoplasia. Aleashia enjoys spending time with her friends, playing sports, dancing and volunteering her time, when not helping us. We hope that Aleashia continues with her vet schooling and becomes a future veterinarian here at White Oaks.

Laurie Rudder, Veterinary Assistant/Receptionist

I graduated initially as a Library Technician in 2020 and quickly realized that the place I needed to be was working with animals. I began working with the team at White Oaks during my placement and was hired after graduation from the Veterinary Assistant program at Durham College in 2022. I’m excited to experience everything that comes through the doors to learn and find my niche. Outside of the clinic I enjoy hiking, reading, video games and spending time with dogs.

Leah Martin, Veterinary Assistant/Receptionist

Leah applied right out of high school into the veterinary assistant program at Seneca College, doing her college co-op here and was hired when the term ended. Leah has always had a love for animals and wanted to work with them. She has 3 cats named Salem, Kilala, and Feyre. She also has two betta fish, Nezuko and Zenitsu. When Leah is not at work or hanging with her feline friends, she enjoys reading, baking, playing video games, watching anime, or painting.

Katie Matthews, Veterinary Assistant/Receptionist

Born in Australia, Katie graduated from University of Queensland with a BAS Hons in Applied Science and Ecology where she gained experience in field ecology, population dynamics, farmwork and zoology.  After arriving in Canada she knew working with animals was still the best fit and gained experience working more closely with cats and dogs since 2014. She currently has two rescue cats named Houdini and Marlon and enjoys exploring more of Canada.
