London Cat Clinic

6 Stanley St
London, ON N6C 1A8


Dr. Sharon Rosenberg  

I graduated from the Veterinary College in Guelph, Ontario in 1989.  I spent 2 years in mixed animal practice before settling in London to do feline medicine and emergency medicine.  I purchased the London Cat Clinic in 1996 and continue to practice feline medicine, surgery, dentistry and behavioural medicine.  Besides being a Veterinarian, I enjoy reading, dancing, cycling,  the outdoors (especially sea kayaking in Georgian Bay and other more exotic locales) and travel in general.  I currently have 3 cats.


Dr. Mary-Anne Maloney  

In 2003, I graduated as a veterinarian from the University of Cambridge in the United Kingdom. I then spent a couple of years working with large animals, including an internship studying Equine surgery in Canada. I moved back to Canada in 2005 and worked with small animals in both emergency clinics and day practice. I started as a member of the staff at The London Cat Clinic in November, 2016. I am happy to be able to provide acupuncture for cats, and have a particular interest in pain management and in the conditions that are seen in older pets.

 My other interests include horse-riding, skiing, ultimate Frisbee and camping. I share my life with 2 cats, 1 dog and a horse.

Stephany Gauthier, RVT

I joined the London Cat Clinic in October 2016. I graduated from Northern College in 2007. From there, I went on to pursue my career in Calgary, where I worked at a small animal clinic for several years. I then decided to move back to Northern Ontario where I worked at a small animal clinic with emergency on-call services where I got to see a lot of interesting cases. After that, I settled in London. I currently have 2 cats at home named Chanelle and Dolce. My hobbies outside work include running, shopping and spending time with family and friends.
