After 5 years in mixed and large animal practice in southwestern Ontario, Brent joined Cannington Veterinary Services in 1998.


Brent has developed a special interest in Equine Dentistry, but enjoys the variety of medical and surgical cases that large animal practice provides. Brent is married to Dr. Sue Talbot, and they are blessed with 2 daughters. Brent enjoys spending time with his family and actively volunteering in pastoral ministry.

Prior to veterinary school, Erin evented up to the preliminary level competing in both the US and Canada. After graduating, Erin spent a year completing an internship at an equine clinic and referral centre in Wisconsin and then went to work at Port Perry Veterinary Services. When not working with animals, she enjoys spending time with friends and family, getting outdoors, playing sports of all kinds, and travelling.


Dr. Rachel Shanahan

Rachel grew up in the Stouffville area before attending the University of Guelph and graduating in 2007 from Ontario Veterinary College. She worked in a mixed animal practice in the Kawartha Lakes area for a year before going to work at Port Perry Veterinary Services. In 2012, Rachel joined on as a practice owner. She gained her certification in Animal Chiropractic in 2014 and offers that to both equine and bovine clients. For fun, Rachel enjoys playing hockey, baseball, horseback riding and hanging with her two kids.


Dr. Rod Schell

Rod graduated from the Ontario Veterinary College in 1977. After several years in mixed animal veterinary practice, he started Cannington Veterinary Services in 1995 as a solo large animal practitioner. For the first few years, it was a family operation with his wife, Deb, and daughters, Denna and Riley, looking after the office reception. He enjoys the challenges of all aspects of large animal practice, but especially dairy medicine and surgery.


Rod and Deb (who may still occasionally be found working around the office) have four adult children and 14 grandchildren.

Dr Rod is now looking forward to transitioning into retirement, with some continuing part-time work in the practice.

In his spare time, Rod enjoys woodworking, renovating his home and cottage, and just spending time at the cottage with his family.


Our Office Staff


Sherry Lewis

Sherry was born and raised in Nova Scotia in a prominent draft horse family. She came to Ontario and has been active in the draft horse industry ever since. She had manned the front office in a few other veterinary clinics before coming to Cannington Veterinary Services in 1999. Sherry and her husband, Stephen, have a 50 acre farm outside of Cannington, where they enjoy raising, training and showing Clydesdale, Shire and a few Percheron horses.

Natalie Silverstone

Natalie came to us at Cannington Veterinary Services in July 2021 after 20 years in regular and referral specialty small animal veterinary medicine. She is now our new main office person, and you will find her doing everything from answering the phones and booking our farm calls to making up all the medications and products our clients need. Natalie lives in Keswick with her husband Christopher and son Derrick and their little Boston Terrier Bruin on the lake. They like to all spend their free time either sitting around a nice bonfire or at their private beach swimming and soaking up the sun. Natalie looks forward to meeting our clients and doing all she can for the practice and our clients for many years to come.
