Entrepreneurship in Veterinary Medicine

After working a desk job for a few years, Cathy Mittenson became interested in finding a career that let her be outside. Between a love for science and growing up surrounded by animals, veterinary medicine was the perfect fit for Mittenson. This led her to apply to NC State College of Veterinary Medicine.

Not only is NC State consistently ranked among the top veterinary programs in the United States, but it is also home to innovative veterinary research and entrepreneurship. When Mittenson graduated in 2018 with her veterinary medicine degree, she found her passion for large-animal medicine through the strong relationships she formed while traveling to clients rather than working in a clinic.

After seven years of experience in veterinary medicine and observing various managerial styles — along with a dusty business degree — Mittenson was ready to dive in and create a veterinary practice that reflects her values as a clinician and supervisor.

Following Her Heart

The field of large-animal medicine is in a state of self-reflection as fewer and fewer vet school graduates choose it as a career. There are changes needed to make the industry more welcoming to new graduates and to ensure it is a sustainable, long-term career.

With a goal to serve as an example to future graduates of how large animal medicine can be a fulfilling, sustainable career path, Mittenson and fellow NC State graduate, Bonnie Swift, started Heart Horse Mobile Veterinary Services, a full-service, mobile vet clinic for farm animals — including horses, goats, sheep and pigs. They provide general preventive care and 24/7 emergency services for the greater Triangle area.

Providing exemplary patient care is just the tip of the iceberg for why Mittenson started Heart Horse. She really enjoys the problem-solving aspect of veterinary medicine and values making clients feel heard and respected. She strives to ensure everyone who loves the patient feels they are part of the team (owners, veterinarians, farriers, trainers, etc.), so they can all work together in the animal’s best interest.

The Journey to Start a Business

Mitteson and Swift had to check many boxes to get their business started in 2025. From researching cell phone carriers, navigating government paperwork and educating banks and loan agencies about the unique properties of mobile large animal medicine, the team worked their way through the list. 

Mittenson noted they are lucky to have the support of colleagues, friends and family. They also had several friends who had started their own practices and provided guidance on what to expect in the first year.

“It is definitely intimidating to go out on your own, not knowing when that first paycheck will come, but our families were very supportive of our endeavor, and that helps tremendously. I am incredibly grateful to be in a position that allows me to pursue this new adventure,” she said.

Exploring Veterinary Entrepreneurship

The veterinary medicine industry can be hard; adding a layer of entrepreneurship can make it even harder. Mittenson leaned on advice from colleagues and friends, noting that the North Carolina Veterinary Medical Board was very helpful.

Networking was also crucial to getting Heart Horse started. From their connections with clients, they got help with vehicle financing, an accountant and a tax advisor.

Mittenson emphasized a few pieces of advice to current veterinary students:

• Maintain relationships that you have developed before and during vet school — you never know who knows who.
• The veterinary field is a tight-knit community, and there is a huge network of support available to you.
• Make checklists and do your research prior to making any financial commitment so you know what the road ahead looks like.
