Dr. Jinni Demine

Owner/Fear Free Certified Veterinarian

“My call to care for animals came to me when I was 4 years old. My friends and I found a stray dog on the streets of Russia and we spent over a week keeping the dog hidden while dog catchers were in our area. Since then I grew up finding those stray animals, cleaning them, feeding them, and bandaging their wounds (sometimes using my own clothes). When I was a young adult, I was accepted into a veterinary school in the city of Moscow which was 2 hours away from the little village where I lived. Every night, when I finally got home from school there was a line of pets with their very preoccupied people waiting for me to treat their various maladies. Breakouts of distemper and parvovirus were common in our building and it was heartbreaking to lose those pets.”

Dr. Jinni Demine graduated from University of Guelph in 2001. She has started her studies in Moscow, Russia right after high school. Her passion has always been ensuring that your pets live long and healthy lives. Her special interest is in dentistry. In fact, Dr. Demine routinely donates her time to perform dentals for pets in Humane Societies and Rescues to ensure they get a great start with their fur-ever families.

Dr. Jinni’s other passion is exotic pet care. Her dream is to be a mom of a Russian Box Tortoise, that is in addition to her dog, Deysi, and her cat, Vasilisa. In her spare time, Dr. Demine is very involved in the community. Her community passion is to promote and initiate any programs through Rotary International involving youth. Dr. Jinni and her 3 children have been a host family for many teenagers from around the world.


Fear Free Certified Practice Manager

“As a child, I always wanted to be a Veterinarian, but I ended up in Public Relations and Corporate Communications, and specializing in Human Resources and Business Management. This afforded me the opportunity to work in a large variety of industries, and the experiences have given me the skills to take care of the people who take care of your pets. Happy staff with a good work-life balance are of the utmost importance to me as it is reflected in everything we do. Being in the veterinary clinic is simply the icing on the cake!”

Andrew was born and raised in Sudbury, Ontario, and moved to the Quinte area in 2015. When he isn’t working or volunteering, he loves spending time with his family, his Jack Russell, Jack, his three-legged Dominican Republic rescue pup, Saul, and detailing his cars.


Fear Free Certified Registered Veterinary Technician

“As long as I can remember I have been fascinated with animals. Everything from their biology to their behavior has captivated my interest. As an athlete, I have also come to love the comraderie and energy that a close-knit team creates. Veterinary medicine allows me to immerse myself in my passion while working closely with a team that shares that passion. There is no other place I’d rather be working.”

Fear Free Certified Registered Veterinary Technician

“I have always loved science and the capabilities each individual living thing has. I grew up eager to take care of the stray animals in my neighbourhood and being attracted to Ontario’s wildlife. After graduating with a Biotechnology diploma in 2015, I realized I could use my science background and love for animals together by becoming a Registered Veterinary Technician to help care for them and my community”.

Fear Free Certified Veterinary Assistant & Treatment Room Coordinator

“From a very early age, I knew I wanted a career working with animals. From walking neighborhood dogs, looking after stray neighborhood cats, volunteering at local horse barns and the Humane Societies, there was always something so satisfying about helping animals in need. I graduated from St. Lawrence College with my Veterinary Assistant certificate and have worked in this amazing field on and off.”

For the past 2 years, Heather has been working closely with Dogs and Cats of the Dominican Republic, helping give a voice to those who can not speak for themselves.
Volunteering in the Dominican in February 2019 with DCDR made Heather realize that she needed to get back in the field she was always meant to be in – helping animals in need!


Fear Free Certified Veterinary Assistant

“Ever since I was little, my family repeated the word “focus” and assured my connection with animals. Becoming a Veterinary Assistant and an Ecosystem Management Technologist, I can indulge myself into the human-nature relationship to protect our companions from the environment. Since 2014, I’ve committed my focus on veterinary care, wildlife rehabilitation, volunteering; and am grateful for the opportunities I’ve had in relation to my field! Animals don’t have voices, and it’s my passion to continue to learn and protect them against any potential hazards”.

Andrea’s commitment to not only animals, but our ecosystem, furthers Trenton Pet Hospital’s commitment to sustainability and drives us forward in our quest of being mindful while practicing medicine. 


Fear Free Certified Client Service Manager

“As a child I have always loved animals. My parents adopted a dog when I was in Grade 1 and it was a day I’ve never forgotten.  She was the best dog.  I knew then that I could never be without an animal in the house.  She passed away when I was in college and as soon as I had my own home I adopted two cats.  From there on my husband and I have had many animals including dogs, cats, chickens, ducks and bunnies.  They bring so much joy to our lives and our children have grown up with a love for animals too.”

Sarah grew up in Trenton and now resides in Frankford with her husband, three children and a small hobby farm of pets, including her cat Dakota and her dogs River and Bailey. She has worked in Customer Service for more than 20 years and is excited to now be working at a Veterinarian Hospital where her love of animals can shine.



Fear Free Certified Client Service Representative

“I have loved animals all my life, and  always felt that I need to be an advocate for them. Growing up I always wanted to be a vet but sometimes life has other plans. I ended up working in the public sector which was also rewarding. In 2012, I had the opportunity to go back to college and chose to do the Animal Care course. Since then I’ve been so fortunate to work with animals. I even took my passion one step further, in 2010 I started volunteering and fostering dogs with some rescue organizations. In 2012 My best friend and I cofounded Just Paws Animal Rescue a foster based dog rescue, and to this date, we have placed over 1000 dogs (and some cats) into their forever homes. We have taken in dogs on death row in shelters, international dogs whose lives looked bleak, and assisted owners who can no longer take care of their pets due to life’s circumstances. I have a beautiful, compassionate daughter, and 2 of my own dogs, and I now feel my life is complete and fulfilled.”
