Dr. Justin Sewell – Veterinarian/Owner

Dr. Justin Sewell was born in Fort St. John and spent his childhood days attending Charlie Lake, Bert Bowes and North Peace schools. He grew up on a farm in the Peace valley where he spent his summers working. After graduation he obtained a biology degree from Trinity Western University in Langley. He and Maradith were married in the summer of 1998 and they moved to Saskatchewan for veterinary college. Their first son Harrison was born the year after graduation, and was joined by brothers Miles, Trace and Barrett over the next 9 years. Maradith and Justin love to travel and enjoy looking for a veterinary conference somewhere they haven’t been. If they are staying home, Justin enjoys getting out into the great outdoors and passing on his love for nature to his sons.

It was always Justin’s goal to move back to his home town and practice medicine. He had a shepherd growing up and knows how much “just a dog” can mean to someone. He understands the stress and anxiety that are present when any family member is ill, and aims to first help clients understand their pet’s condition and then work through the decision making and treatment processes with them. It really is about helping people . . . Care for their pets.


Dr. Steve Chapman

Dr Steven Chapman is a local grown talent. Graduating from North Peace Secondary School in 2009, he had already been volunteering with us for three years. Coming back each summer for employment, Steven worked his way through school completing his BSc in biology at UBC Okanagan in 2013. He was accepted into the Western College of Veterinary Medicine where he completed his veterinary degree in 2017. At Rivers Animal Hospital, Dr. Chapman has developed his interests in large and small animal medicine, traveling to “the field” to help the larger patients. His dog, “Goose” is often his wingman on these trips and is always around when Dr. Chapman is enjoying the many fishing and hiking opportunities in the area.


Maradith Sewell – Owner

Maradith was born in Victoria, but moved to the mainland before she turned 2. She grew up in Maple Ridge on the South Allouette River. Years of swim club involvement lead to work as a lifeguard, swim instructor, aquafit instructor and swim coach. These jobs brought Maradith to the north for the first time after graduating from Maple Ridge Secondary School. For 4 summers she would return to work in Dawson Creek while pursuing her Bachelor of Science in Kinesiology. After meeting and marrying Justin Sewell in 1998, she transferred to the University of Saskachewan to complete her degree. Maradith continued to work with a physiotherapy clinic, a chronic disease management program, and fitness instruction classes while Justin completed his veterinary studies.

Maradith and Justin now have 4 wonderful boys: Harrison, Miles, Trace and Barrett. The past years have been spent raising boys, while continuing with her love of teaching fitness classes and courses. Many mornings are spent inspiring people to get active and enjoy it, afternoons are spent connecting with clients and their pets here at Rivers, and evenings are filled with the excitement of watching their boys play soccer.
Maradith’s personal interests involve travelling with her family, baking, teaching fitness classes, spending time with their church family and being artistic.
