Dr. Katrin Schmidt, DVM

Hospital Administrator and Chief Veterinary Director

Dr. Katrin Schmidt is in charge of making sure all team members understand their impact on the client-and-pet experience to ensure a better outcome for all. She was born and raised in Germany in a rural mountain setting. She enjoyed horseback riding and country living at an early age. In fact, she spent most of her childhood working with animals including horses. Training horses exposed her to many of the behaviour principles we apply to most species, including humans. As a teenager, she lived in Dallas, Texas, and Hudson, Quebec. 

Dr. Schmidt has always had a passion for medicine, science, and technology.  Her interest and experience in solving complex problems with new and unique ways led her to attend the Veterinary College in Guelph. Veterinary medicine seemed just a little bit more challenging than human medicine or computer science. 

Since graduating with a BSc. in 1991 and a DVM in 1993, Dr. Schmidt—along with her husband, Dr. Bolton—has been a veterinary practice owner since 2000. She co-founded the Barrie Veterinary Emergency Clinic in 2001. As primary patient care coordinator and hospital administrator, it was important for her to be adequately trained in patient and client care as well as business needs. So in 2004, she completed her Certificate of Veterinary Practice Managers diploma and most recently graduated from the MBA program at Lakehead University. 

With her work experience in veterinary community services, she is able to help clients and members of the team with personal and professional challenges and dreams. Helping others succeed in improving pet health and strengthening the human animal bond continues to be a rewarding experience. As a constant learner, she also enjoys educating and coaching others. 

Dr. Schmidt is very fortunate to have her immediate family residing in the Barrie and Orillia area. She lives with her husband, Dr. Bolton; their two children; and their Doberman and ponies in lovely Horseshoe Valley. The family loves spending time outdoors both in the summer and winter. 

Dr. Holly Spring, DVM  


Dr. Spring grew up on the family dairy farm in Elmvale, where her childhood was enriched with many different animals, from cats to cows. She loved to work with the animals and was inspired by the family farm vet who treated the sick animals. 

Dr. Spring attended the University of Guelph and completed her undergraduate work in animal biology. She volunteered and worked at clinics to get experience. She went on to complete her Doctor of Veterinary Medicine at the Ontario Veterinary College. Now, she works with companion animals, mostly dogs and cats. She performs surgery and examinations. She also educates clients about preventive care, nutrition, pain management, and dermatology.  

Dr. Spring and her husband, Dr. Cameron Lindsay, have a household of furry children. Maude is their happy go lucky Boston terrier. They also have four cats named Jim, Pete, Herb, and Ronald. She likes spending time with friends and family, CrossFit training, and cross country skiing in her spare time.

Lindsey’s passion for the wellbeing of animals began at an early age; she remembers having a special fondness for her family’s pet cats and attending vet visits with her parents. Dr. Rogers has remained a Simcoe resident and has spent the last 8 years working in a small animal practice in Barrie. Her and her husband Eric live in Springwater where they spend their time getting together with friends for game nights or catching up on the news.

When not at home or the cottage, Lindsey and Eric spend their time taking care of their pet family: Carter, a 6year old golden retriever who is the best behaved of the bunch, always willing to please and greet you with a toy; Ernie, a smooth coated Brussels Griffon puppy, is the new addition to the clan who always has the family laughing at his antics; and Lenny and Carl – 11 year old domestic shorthair brothers. Lenny can be found anywhere there is food or a plastic bag to chew on. Carl can be found screaming outside the bedroom door at 6am when it is time for love.
