Andrew also does some CQA for swine clients. Andrew and his wife Cheryl have four children, Scott, Lauren, Reid, and Tessa.
Dr. Emma Webster
Emma Webster spent her veterinary externship with us in 2008, and so we knew we were very fortunate to have her join our team when she graduated from the Ontario Veterinary College in 2009. In addition to an admirable level of general veterinary knowledge, she has taken a comprehensive course in ultrasound and dentistry and has a special interest in Ophthalmology. Outside of the clinic, Emma enjoys horseback riding, painting, and spending time with her family on their hobby farm in Drayton. Emma shares the farm chores with her husband Rob, three children (Miles, Sidney, and Samantha), their dog Kajun, their cat Spencer and about 20 chickens.
Dr. Kelly Barratt
Kelly has been on the Heartland team since she graduated in 2005. She is now a part-owner and spends her days split between doing dairy cattle herd healths and working with Dairy Farmers of Ontario as a quality assurance program consultant for the proAction program and other Canadian dairy industry projects. Kelly was awarded a “Top 40 Under 40” in Agriculture for North America by Vance Publishing in 2014 and the Ontario Association of Bovine Practitioners Award of Excellence in 2017. When she is not at work, you can find her working alongside her dairy farmer partner, Adam, and their young son, Noah. Kelly’s other hobbies include riding her dressage horses, traveling, wine and cheese tasting, and she has recently taken on a farm project of her own – beekeeping!
Dr. Christie Morrow
Christie graduated from OVC in 2010, and her strong interest in dairy cattle medicine led her to Listowel upon graduation. After being away a few years, Christie rejoins the Heartland team to pursue her dairy production systems and embryo transfer passions. She completed the embryo transfer training course in Saskatoon with Dr. Reuben Mapletoft in 2013 and looks to explore all opportunities in this field. When not working, you can find Christie enjoying time with her family on their dairy farm with their dogs Lightning and Frankie. The Heartland management team excitedly welcomed Christie as co-owner in January of 2020.
Dr. Kim Watson-McKenzie
Kim Watson-McKenzie had a rural upbringing, and animals have always been an important part of her life. She graduated from the Ontario Veterinary College in 1994, started her position in Listowel in January 2005, and became a co-owner in 2008. Kim has extensive experience in both Medicine and Surgery. Kim and her husband, Rob, enjoy spending time with their three children Melynda, Brayden, and Turner, and continue to be the kids’ biggest fans no matter what sport they are participating in. They also appreciate visits with family ‘back at the farm’, daily walks, and any opportunity to ride their motorcycles. They have an energetic yellow lab named Nala and a playful cat named Ike.
Dr. Mary Walker
Mary Walker graduated from the Ontario Veterinary College in 2011 and is happy to be splitting her time between Heartland Animal Hospital of Listowel and Drayton. Mary grew up in the city of Brampton and is enjoying the more rural lifestyle that Listowel offers. Mary has an interest in pain management in her surgical and medical cases. This past spring, she participated in a comprehensive course on abdominal ultrasound and just completed a similar course for horses. Mary loves to travel, read, and relax with friends and family at her family cottage in her free time. She lives in Listowel with her loveable but mischievous dog Wiley “The Coyote.” He is a rescue from a Northern Ontario native reserve and is a constant source of entertainment (and trouble) in his efforts to be an indoor dog!
Dr. Rod Wieringa
Rod graduated from the Ontario Veterinary College in 1994. After graduation, Rod practiced in Stratford for just over a year before moving to Listowel to work at Heartland Veterinary Services. Heartland’s large progressive dairy practice was the main attraction to move to Listowel. Shortly after arriving, Alton MacKay asked Rod to start flushing cows with him. Rod is a graduate of OVC’s Dairy Health Management Certificate Program and has a strong interest in embryo transfer technologies and dairy production medicine. What brings Rod the most satisfaction is being part of the next generation of veterinarians and staff as they develop their skills and help our clients achieve success. Rod lives in Listowel with his wife Lisa, and their two boys Matthew and Carter, and golden retriever Murray.
