Meet the Team

Dr. Lindsay Paterson - BVSc (Hons) MRCVS

I was born in Scotland and later immigrated to South Africa where I completed my education and qualified from Onderstepoort, University of Pretoria. I spent many years working in small animal practice and completing my post-graduate honours degree, before joining the Johannesburg SPCA in 1990 as Assistant Chief Veterinarian. As a team of five vets, we also gave veterinary care to the African township of Soweto. Here I spent two fascinating years and gained a huge amount of experience covering a range of medical and surgical problems, many not frequently seen in normal private practice.

I then decided to open my own clinic in Sandton, north of Johannesburg, where I spent the next ten years running a smaller, very personal practice, getting to know the clients well, their pets and often their extended families - two and four-legged.

While awaiting our Canadian immigration application approval, I spent a glorious year working in private practice in Aberdeen, Scotland. Despite the beautiful countryside, wonderfully friendly people and colleagues, as I was unable to find a Scottish castle to fit my budget, I continued on to Canada as originally planned.

In 2005 I completed my North American Veterinary Licensing Exams and worked for the next four years at Lawrence Veterinary Clinic, and then later worked for the Toronto Humane Society. During this period I also took time off to visit India and volunteered with Vets Beyond Borders in Sikkim, a beautiful country, wonderful people and a very rewarding experience.

Having been lured by the pleasant "village" atmosphere of this location on Summerhill Avenue, I felt it was very suited to the smaller more personalized style clinic I enjoy. I had had my eye on the spot for years and was delighted when it finally became available.

Between raising five children (with music, hockey, tennis, judo, ballet, etc. ) and running my own clinic in South Africa, there was little time for personal hobbies -absolutely no regrets. However, in my next life, I will learn to play the piano, fly a helicopter, make stained glass windows, do falconry and competition dressage and own that Scottish castle- complete with a personal chef!

Now, as an empty nester, I now have three yorkies, Noodle, Pixie and Abi - who are often seen running off leash and out of control in Chorley Park!



Dr. Tiffany Mason - DVM

Tiffany grew up in Toronto and lives in the east end of the city with her husband and 2 children. She is currently living without a pet (gasp!), having recently lost her 19 year-old orange kitty, who was named Carrot. A new pet is definitely on the horizon for her. 

Tiffany received her Honours Bachelor of Arts degree in Psychology at Queen’s University, followed by her Bachelor of Science degree in Biology at the University of Guelph. She graduated from the Ontario Veterinary College in 2004. Becoming a veterinarian has fulfilled her childhood dream and makes “going to work” every day a true pleasure. Her veterinary interests include oral health care, geriatrics and feline medicine. When not working with the animals, Tiffany enjoys checking out live music, reading, puzzles and hanging out with her family.



Sivanne Detsky - Registered Veterinary Technician (RVT)

As far as I can recall I always knew helping animals would be my career. Throughout high school I worked at a 24 hour emergency veterinary clinic as an assistant, and learnt of the Veterinary Technician role in the hospital. After graduating high school I attended St. Clair College in Windsor, ON and in 2005 became a Registered Veterinary Technician. For the better part of the last decade I’ve worked as a veterinary technician at a very busy small animal hospital in Toronto. In June 2014, I joined Rosedale Moore Park Veterinary Clinic and am thoroughly enjoying the community practice Dr. Paterson has developed in this beautiful neighborhood. 

While most would think once I leave the clinic for the day I leave the excitement behind, I actually return home to an equally busy and pet filled home with my 3 children (Jordyn, Ari and Eliav), 2 Cairn Terriers (Tucker and Annie) and my 2 rescue cats (Colin and Maggie). My days are always busy and exciting, but I wouldn’t trade it for the world.



Jo Bishop  RVT

Born and raised in the Leaside neighborhood of Toronto, I have always grown up with a love of animals. I had always immersed myself in jobs working in animal care positions throughout high school before deciding that becoming a veterinary technician was right for me. I graduated from St. Clair College in Windsor, Ontario in 2008 and had worked at the same small animal clinic since graduating before being enticed by the lovely vibe and atmosphere of the Rosedale Moore Park Veterinary Clinic. Outside of the practice, I currently reside in Leaside with my golden retriever Gracie and newest feline addition, Larkin. I enjoy going horseback riding, golfing and spending summers at the cottage.




Natasha Nanji  RVT

Natasha graduated from Seneca College in 2017. While at Seneca, she fell in love with all things four legged and landed a job at the Toronto Humane Society. After graduating, she spent a month in Thailand working at the Baan Unrak Thai Animal Sanctuary where she was able to develop her technical skills in small animal care. Natasha is so excited to join the Rosedale Moore Park team and work with people as passionate as she is. She currently has found her spirit animal in her cat Olive and has just adopted a mystery mutt named Luna from the humane society.







Joanne Lavery - Receptionist

I was born in Northern Ireland during a time of political strife, so at a very young age my parents decided to immigrate to Canada to make a better life for my sister and me.

I grew up in Brampton Ontario, in a suburban setting like many other new Canadians. As a young girl I soon discovered my love for furry four legged companions and at sixteen I started my first job at the local Brampton Animal Shelter. I did my high school co-op placement at a neighbourhood veterinary clinic and after that I was hooked. I continued to work part time at veterinary clinics throughout my high school years. I knew from an early age that rescuing, fostering and finding forever homes for animals was going to be more than just a job, it is my calling. Over the years I've developed a knack for placing homeless pets in their forever homes and I have numerous “happy ever after” stories.

For the last 25 years I've worked within the veterinary field as a groomer, vet assistant, receptionist and office manager and can truthfully say I’m still passionate about my work and love working in the veterinary field.

I met Lindsay at a previous clinic and worked with her for four years and so when the opportunity to work with her again came up, I jumped at it. I am now happily a team member at the Rosedale Moore-Park Vet Clinic.

Currently I have two rescue dogs (both one-eyed), a Pekingese named Farrah Fawcett and a Shih Tzu Mix named Enzo Ferrari. On my off hours I like to enjoy a glass of wine with my husband Seamus on our back deck with the dogs.


Rebecca Keddy - Veterinary Assistant

Born and raised here in Toronto, I have always had animals in my life. In my family, I was the one who always took it upon myself to care for them. Shortly after graduating high school in 2013 I was helping out one of Dr. Paterson’s children, who by chance mentioned to me that his mother owned a veterinary clinic. We connected immediately and she took me on as an assistant, I have been here ever since. Working at this clinic has been an amazing experience; I am hoping to return to school to become a registered veterinary technician. My partner and I have a husky/blue heeler mix named Leo and a husky named Lucy. Every time I come to work I am always excited to see my coworkers and to be there for our patients.
