Our Veterinary Partners

Dr. Thomas Veens


Thomas graduated from the Ontario Veterinary College in 2012 and immediately joined Heartland Veterinary Services to pursue a career as a farm animal practitioner specializing in dairy cattle. He became part owner in 2016. Thomas’ main focus is herd health, with a special interest in reproduction, calf and heifer rearing, transition cow management, disease prevention, and protocol development. In addition, Thomas works with bulls at artificial insemination centers and is part of the embryo transfer team at Heartland. Thomas is also very interested in surgery and enjoys performing many different surgical procedures. Thomas lives in Fordwich with his wife, Angelika, and children, Julia and Henry. He enjoys hiking, camping, canoeing, kayaking, various other sports, and traveling in his spare time.

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. 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.
