She discovered the OTCC as a veterinary student, and immediately knew it was the place for her; now, it is the main focus of her career. Turtles are very special patients, and she has a particular fondness for giant snapping turtles. She loves the challenge of caring for each individual, and contributing to the conservation of wild populations with every successful release.
At home, Kristen and her husband surround themselves with nature and gardens, and share their lives with multiple furry senior citizens who keep them endlessly entertained and busy when not at work.

Dr. Sabrina Cirone, Veterinarian
Dr. Sabrina Cirone has had a lifelong interest in reptiles. She grew up with unconventional pets such as snakes, water dragons, and geckos since the age of 9.

Justine Hewitt, RVT
Justine joined the Turtle Team in January of 2022. She became smitten with turtles while working at a veterinary hospital that acted as a First Responder to OTCC. When we advertised for a full time technician, she knew this was for her! Justine brings a wealth of experience, and always has a smile on her face. Justine had the happy news in 2022 that she was expecting her first child, and left for a parental leave in the spring of 2023, but we look forward to seeing her back in 2024! Justine lives on a working farm some distance from OTCC, so is always kept very busy!

Selena Kirkland, Hotline Coordinator
Selena found out about the OTCC during her herpetology class while completing her Bachelor of Science degree in Biology at Trent University. As soon as she heard the organization hired summer students she knew she had to apply. She fell in love with the cause and working directly with the lovely Turtle Taxi volunteers who dedicate so much of their time and energy to the cause. This pushed her to get a specialization in Conservation Biology and do her school placement at the OTCC, before returning to the summer Hotline position the following year. When the full time position became available she was overjoyed to join the team as the Hotline Coordinator so she could continue to work with all the lovely staff and volunteers year-round.

Tracey Murfin, Grant Manager
Tracey has over 35 years of experience working in not-for-profit organizations specifically Children’s Mental Health. She has held both front-line and management positions and brings many skills specific to writing and developing programs, which makes her a good fit for the Grant Manager position. Tracey received a Social Service Worker Diploma from Fleming and attended the BA Social Development Studies Program through the University of Waterloo. Her passion for nature and photography has provided her with many hours of pleasure watching and photographing snapping turtles hatch near the family cottage. When she retired recently, her first task was to volunteer feeding turtles at OTCC. This has led her to the Grant Manager position.

Kate O’Day, General Manager
Kate has always had a love for animals, and has a soft spot for amphibians, reptiles, and insects. Like many of her coworkers Kate has a passion for wildlife conservation, science and turtles – though she refuses to pick a favourite one. Kate first connected with the Ontario Turtle Conservation Centre while completing an Honours degree in Biology with a minor in Environmental Science at Trent University, through an education workshop on the OTCC’s mission. She was quickly drawn in – and hasn’t really left since.
What started as volunteering in 2019 gradually turned into a range of roles, including summer student, Hotline Coordinator and General Technician – assisting in a range of OTCC needs, before moving into her current position as General Manager of Non-Veterinary Programs. Before joining the OTCC, Kate’s experience included operations management in a for-profit setting for several years, along with time spent in small-scale farming and volunteering in the local not-for-profit sector. Along the way Kate also completed a Professional Certificate in Not-for-Profit Management from Western University.
Kate enjoys the ever-changing, puzzle-like nature of her work and values the opportunity to connect with others in conservation while helping to engage and inspire new people to get involved. In her downtime, Kate enjoys spending time outdoors, reading a good book, and taking part in a competitive board game session!

Audrey Payne, Volunteer Coordinator
Audrey has had a connection with animals and nature her entire life, from bringing home barn cats from the farm down the road to collecting minnows in the lake with her brothers. She spent over 4 years working as a veterinary assistant and communications representative at multiple VCA small animal clinics, fostering her love of animal care and vet medicine. While working at veterinary clinics, her passion for environmental conservation persisted and led her to completing her bachelors of environmental science/studies at Trent university in 2025. While at Trent she escaped the academic chaos by becoming a volunteer cleaner at the OTCC. This led to a placement and in the summer of 2025 she worked on the animal care team. The organization opened her eyes to opportunities in conservation of species at risk and the ability to rehabilitate injured animals. After having the amazing guidance from the former volunteer coordinator, her excitement for education and animal husbandry led her to becoming the Volunteer Coordinator in the fall of 2026. When she first came to Peterborough she had no idea that her life would be so rich in helping strengthen our relationship with Ontario’s turtles and the members of our community who share her love for these amazing creatures!

Kelsey Scott, Education Assistant
When Kelsey found out that Peterborough was home to the OTCC, she knew that Trent University was the right place for her. She began volunteering at the centre during her first year in 2020 and completed co-op placements with the hotline and education team as part of her Conservation Biology degree. Kelsey’s passion for wildlife conservation continued during her semester abroad, where she gained hands-on experience with the Port Macquarie Koala Hospital and Dolphin Research Australia. After graduating in 2024, Kelsey pursued an internship with the Orca Behavior Institute on San Juan Island, studying 2 populations of killer whales. When the opportunity arose to work with the turtles again as Education Assistant, Kelsey knew she couldn’t pass it up. She is grateful to be a part of such an amazing team dedicated to important and rewarding conservation work! Kelsey is also an avid wildlife photographer and enjoys capturing the beauty of the natural world through her lens.

Becca Withers, RVT
Rebecca (Becca) has a very long history with OTCC, dating right back to 2009! Becca was the very first veterinary technician who helped OTCC, back before we had the funds to pay for any staff! Becca was such a help and came in every day to do treatments for an entire season – as a volunteer! Sadly, she did eventually have to leave to go to a paid position. Fast forward to 2023 and her path crossed again with Dr. Sue Carstairs, and they were able to catch up. At the time, we were looking to hire another veterinary technician, and Dr. Carstairs invited her to apply…and that is how Becca came to be a valued member of the OTCC team once more! A wonderful ‘full circle’ story. Outside of turtles, Becca’s passions are many, including being a very talented artist.
