Karen Miller: a Lifelong Love of Animal Health

Karen Miller’s passion for animal health began long before her professional career took off. Growing up on a farm, she was the family member tasked with assisting the veterinarian, gaining hands-on experience that would shape her future. Her participation in 4-H showing horses, dogs, and beef calves, further nurtured her understanding of animals and their care, while also instilling a lifelong curiosity about the science behind their health.

Encouraged by mentors, including her family’s veterinarian, to pursue science and math, Miller knew she wanted to work in the animal health industry.

Acceptance into the University of Minnesota’s Animal Health Technology program at the Waseca campus marked a major launching point. Only 32 students were admitted each year, and Miller began just two weeks after graduating high school, facing a rigorous panel of faculty and administrators. The program’s demanding academics, strict grading policies, and professional expectations – white lab coats at all times, no casual attire – instilled in her the discipline and professionalism that would carry through her career. “The program taught us to always present ourselves professionally, and that has served me well for five decades,” Miller said.

From those early days on the farm to a pioneering career in veterinary technology, sales and leadership, Miller’s story is one of dedication, adaptability and a profound love for animals. Recently retired, her 50-year career illustrates how early experiences, mentors and a commitment to professional growth can shape not only a career but an enduring legacy in the animal health industry.

The Shifts That Shaped A Career

Miller’s career spans a diverse range of roles across the veterinary and animal health industries. She began as a veterinary technician at Cullen Veterinary Clinic before moving into sales with SmithKline Beecham, Ciba-Geigy, and later Novartis, where she built strong relationships within the veterinary community. After working independently as a practice consultant, she joined Midwest Veterinary Supply, where she served as companion animal director, bringing decades of hands-on and strategic experience to the role.

Over the course of her career, Miller has had a front-row seat to the sweeping changes that have reshaped veterinary practices, product development and the industry’s workforce. Reflecting on her years in the field, she points to several defining shifts that helped shape both her journey and the profession as a whole.

“One of the biggest changes I saw,” she recalled, “was the shift from mixed or large animal practices to companion animal focused clinics.” In her early years, many clinics primarily treated production animals, with small animal appointments squeezed into brief windows late in the day. Over time, these practices evolved into dedicated small animal clinics, catering exclusively to pets. This shift mirrored broader societal changes, including increased pet ownership and the growing role of pets as family members.

Miller also reflected on the early gender dynamics of the profession. “Walking the halls at the University of Minnesota, every class photo on the wall was filled with men,” she recalled. At the time, the field was overwhelmingly male, and there were few, if any, visible role models for women entering veterinary medicine. Today, women make up the majority of veterinary students. Miller believes this shift helped shape a profession that’s not only highly skilled but also deeply connected to the emotional needs of pets and their people.

The evolution of veterinary products, particularly parasiticides, also stands out in her career. Early on, clinics received truckloads of multiple products to address fleas, ticks, and intestinal worms, requiring complex, multi-step treatments. Today, single products manage multiple conditions, streamlining care and improving convenience for veterinarians and pet owners alike. “That was mind-boggling to see,” Miller said, noting that parasiticides remain one of the top revenue categories for veterinary hospitals.

Miller was also part of a watershed moment in 1995 when Ciba launched the first nationally televised animal health product aimed directly at pet owners. Initially, some veterinarians were skeptical, or even irritated, by clients asking for products advertised on TV. Yet, the campaign marked a turning point, pioneering consumer-focused marketing in the industry. Now, she said, veterinary clinics routinely market directly to pet owners with their own online stores and campaigns.

Fulfilling Work

Miller describes her time with Midwest Veterinary Supply as some of the most meaningful and rewarding of her career. She first partnered with Midwest while working as a manufacturer’s rep and had long admired their approach to business and client relationships. When it came time for a new chapter in her career, she reached out, and the team welcomed her with openness and trust.

“They didn’t have a defined position when I came on board,” she recalled. “But Jeff Burkhamer encouraged me to find where I could make the most impact.” That trust gave Miller the space to help shape what would become the role of companion animal director, a position that allowed her to bring together her experience, curiosity, and passion for veterinary care.

“I always felt supported in exploring new ideas,” she said. “They gave me room to grow and contribute in ways that felt meaningful.” Miller credits Midwest for cultivating a culture of learning, innovation and respect that kept her energized and connected to the work for many years.

Equally significant for Miller has been her experience in the broader animal health community. She describes it as a unique and empathetic network, united by a shared love for animals. “People drawn to this industry are sensitive to the needs of others,” she said, noting how veterinarians and industry professionals come together in times of crisis, from mental health challenges to natural disasters. Colleagues across states support each other during wildfires, floods, hurricanes or other emergencies.

Miller also observes how the community celebrates professional achievements. When someone rises to prominence or accomplishes something extraordinary, the industry collectively congratulates and showcases them. She attributes this to the relatively small size of the community, which fosters warmth, connection and genuine care. “It’s not a big community,” she said. “We take care of each other, and we support each other. That’s what makes it special.”

Mentors and Their Impact

Miller credits much of her 50-year career in animal health to the mentors who shaped her personal and professional growth. “My parents were my first mentors,” she said, instilling in her and her siblings the importance of a strong work ethic, treating everyone with respect, and always considering other perspectives. These early lessons became guiding principles throughout her career.

Dr. Clough Cullen, the founder of the University of Minnesota’s Animal Health Technology program, stands out as her most influential professional mentor. He not only designed the program to define what veterinary technicians could achieve but also encouraged Miller personally. After graduation, he invited her to work at his clinic. “He taught me the value of education and learning, and that’s been key in my success,” Miller noted.

After her technician role, Miller shifted to academia at Dr. Cullen’s request, teaching with him at Waseca. She carried that focus on education forward, coaching pet owners, students, clinic staff, and veterinarians.

Another key professional mentor, Charlie Benz, helped Miller understand that relationships are the true currency of the animal health world. Through their collaboration, Miller discovered that real networking had nothing to do with business cards. It was about listening, bringing the right people together, and building genuine relationships. Over the years, she welcomed the opportunity to foster those connections – introducing colleagues to new opportunities, helping clinics find the right support and solutions and quietly opening doors for others behind the scenes.

Networking, for Miller, isn’t transactional, it’s deeply human. It means remembering names, following up with intention, and believing that everyone has something to contribute. “The last conference I went to, I could walk through the halls and people would greet me by name,” she said. “I love that.” Those hallway greetings were more than a sign of recognition; they were proof of a career spent building real connections across an industry she loved.

Helping and Serving

As Miller reflected on chapters of her career in animal health, her advice to newcomers is rooted in listening, curiosity and service. “Listen more than you talk,” she said, noting that asking questions and valuing others’ experiences is crucial. “Realize and acknowledge that everyone has had some kind of experience, and it’s valuable.”

Miller believes that not everyone arrives with the same education or background, but that’s exactly what makes the profession stronger. “Everyone has something to bring to the table. Everyone has lessons to share, and we all have something to learn.” She encourages professionals at every level to stay open to new perspectives and to approach each conversation with humility and curiosity.

That openness includes the ability to ask for help – something Miller sees not as weakness, but as a strength. “There’s real power in admitting when you don’t know something,” she said. “It builds trust. It invites connection. And it shows you care enough to get it right.”

For Miller, the profession is defined by its purpose: helping and serving. “How can I serve and how can I help? That’s what this profession is all about,” she said. Love for the work, she added, is essential. Many colleagues who temporarily leave the field often return, drawn back by the profession’s unique fulfillment.

Relationship building has been central to Miller’s success. She describes it as both instinctive and intentional – a foundation for her career and her life. Whether visiting a clinic, attending a conference, or mentoring colleagues, she makes a point to be fully present, genuinely engaging with others. “I believe everybody has a story, and I love to hear their story,” she said. Over time, her dedication to maintaining connections has created a broad and enduring network, one she can rely on for problem-solving, advice, and collaboration.

As she enters retirement, Miller expresses pride in her career and excitement for what lies ahead. Known for her adventurous spirit, she’s embracing this next chapter as a chance to say “yes” more often – to people, to possibilities, and to experiences she once had to schedule around work. Among her long-awaited goals is an African safari planned for April 2026 with high school friends, led by classmates who grew up in Tanzania. She is eager to explore the continent, experience wildlife firsthand, and share the adventure with friends. “People think I’m very spontaneous, but now I want to say ‘yes’ to every opportunity that comes my way. Let’s try it. Let’s do it.”
