Few leaders in the animal health industry have successfully combined Veterinary medicine, marketing expertise, technical innovation, and people leadership as seamlessly as Dr. Cristiano von Simson. Over the course of more than three decades, his career has taken him from treating racehorses in Brazil to leading marketing and Veterinary services for one of the world’s leading animal health companies.
Along the way, he has helped launch some of the industry’s most recognizable products, built high-performing teams across multiple continents, and demonstrated how scientific expertise and business strategy can work hand in hand to improve the lives of veterinarians, pet owners, and animals alike.
During his appearance on The People of Animal Health Podcast with Stacy Pursell, founder and CEO of The VET Recruiter, Dr. von Simson reflected on the unexpected twists that shaped his career, the importance of lifelong learning, and why curiosity has remained his greatest professional asset. Throughout the conversation, one message emerged repeatedly: success isn’t about following a perfectly scripted career plan—it’s about remaining open to opportunities that align with your passions.
A City Kid Who Fell in Love With Horses
Unlike many equine veterinarians, Dr. von Simson didn’t grow up on a farm or ranch. He spent his childhood in São Paulo, Brazil—one of the world’s largest metropolitan areas.
“I grew up in a big city in São Paulo,” he explained. “A typical urban child. No big farm relations or anything.”
Yet one childhood experience changed everything. Around the age of seven or eight, he visited the mountains and encountered horses for the first time. It was an unforgettable moment.
“For some reason,” he recalled, “I fell in love with horses.”
That fascination quickly evolved into something much deeper. Rather than becoming simply a hobby, horses became the driving force behind nearly every major decision he would make over the next several decades. His educational path, career choices, and ultimately his journey into the animal health industry all began with that single childhood experience.
Looking back, Dr. von Simson credits his love of horses as the catalyst for his entire professional life.
Pursuing a Dream in Equine Veterinary Medicine
When it came time to choose a career, Dr. von Simson never seriously considered another profession. His goal was singular.
“I decided to go to Veterinary school specifically with a single focus of being an equine veterinarian,” he said.
He attended Veterinary school in São Paulo before completing a highly competitive residency at one of Brazil’s premier racetracks. Each year, only six residents earned positions in the program. The experience proved valuable. With approximately 3,000 Thoroughbreds housed at the facility, residents gained extraordinary exposure to equine medicine and surgery.
“They had 3,000 horses stabled there,” said Dr. von Simson. “So there was a lot of experience—hands-on experience.”
Rather than spending years gradually building case experience, the racetrack accelerated his professional development. The volume and complexity of cases exposed him to conditions few young veterinarians encounter so early in their careers.
By the time he entered private practice, he possessed a level of confidence and clinical experience that would normally require many additional years to acquire.
An Unexpected Turn Toward Industry
Although equine practice fulfilled a lifelong dream, Dr. von Simson eventually began feeling something unexpected. He enjoyed the work. He loved his patients. He appreciated the relationships he had built. Yet something was missing.
“I realized that I was happy,” he said. “I was working a lot, I was having a lot of fun . . . but I felt somewhat in a routine.”
More importantly, he no longer felt challenged: “I wasn’t learning anything new.”
For someone naturally driven by curiosity, that realization became impossible to ignore. “I am one of those people that always needs to be learning more and needs new challenges,” he said.
A conversation with a former Veterinary school classmate unexpectedly opened an entirely new career path. His friend worked for an animal health distributor and began describing the wide variety of roles veterinarians could pursue within industry. Until that conversation, Dr. von Simson had given virtually no thought to careers outside clinical practice.
“I had very little knowledge of what veterinarians did in industry,” he said.
Soon afterward, an opportunity emerged. A company preparing to launch its companion animal business in Brazil needed a veterinarian to provide technical support for its equine vaccine portfolio. Although the transition represented a significant change, it also allowed him to remain connected to horses.
“It wasn’t that dramatic a rupture,” Dr. von Simson explained.
Little did he know that the position would ultimately launch an entirely different career.
Discovering a Passion for Marketing
Dr. von Simson entered industry expecting to spend his time educating veterinarians about equine vaccines. Instead, he quickly found himself solving a completely different problem. The company had developed excellent products. What it lacked were marketing materials.
“When I showed up for work,” he recalled, “I asked, ‘What materials do I have to share with veterinarians?'”
The answer surprised him: “They said, ‘We don’t have it yet. Can you help us do it?'”
That simple request introduced him to marketing. Soon afterward, he assumed responsibility for companion animal vaccine marketing before helping launch one of the most transformative products in Veterinary medicine: Frontline®.For today’s younger veterinarians, it’s difficult to appreciate just how revolutionary the product was when it entered the market.
“It was a big game changer,” Dr. von Simson said.
Unlike previous flea control options, Frontline dramatically changed parasite prevention and quickly transformed companion animal medicine in Brazil. “It grew like crazy,” he recalled.
The experience also transformed his own career: “I was fortunate to be in the right place at the right time.”
Recognizing that practical experience alone wasn’t enough, he enrolled in an MBA program to strengthen his business knowledge. “The fact that I had already done some marketing before taking the course was really good,” he explained.
Because he understood the day-to-day challenges, the classroom concepts immediately became applicable. That combination of Veterinary training and formal business education would become one of his greatest professional strengths.
Building a Global Career
Dr. von Simson’s growing success in marketing soon created opportunities well beyond Brazil. Following the merger that formed Merial, he accepted an invitation to join the company’s global marketing team in the United States. His family relocated in 2000, beginning the next chapter of an increasingly international career.
Over the years, he held leadership positions across global marketing, U.S. marketing, pharmaceutical product management, Veterinary services, and key opinion leader development. Each opportunity expanded both his responsibilities and perspective.
One particularly meaningful role involved building a formal strategy around relationships with Veterinary opinion leaders. Rather than maintaining isolated contacts across different departments, Dr. von Simson helped create a coordinated, long-term approach. “It was really a strategic approach,” he explained.
Developing trusted relationships with specialists and thought leaders requires patience; “You don’t do that in a week or two.”
Instead, success depends upon consistency, trust, and a genuine commitment to supporting Veterinary medicine over many years. That long-term mindset continues influencing how he approaches both leadership and marketing today.
A Leadership Opportunity That Changed Everything
One of the most significant turning points in Dr. von Simson’s career came unexpectedly. When recruiter Stacy Pursell contacted him about leading Veterinary Services at Bayer Animal Health, his initial response was surprisingly hesitant. “I told you I wasn’t interested,” he admitted with a laugh.
At the time, he viewed the position as the pinnacle of a Veterinary Services career. “I thought I was too young to be at the top,” said Dr. von Simson.
After discussing the role in greater detail, however, he realized the opportunity involved much more than managing technical services. Bayer wanted someone to transform Veterinary Services into a strategic business function capable of supporting the entire organization. Equally important, the position offered his first opportunity to lead a large team.
Managing people proved unlike anything he had previously experienced. “What I learned,” he reflected, “is that’s the only thing that never becomes routine.”
Products change, markets, evolve, strategies shift, but helping people develop their careers remains endlessly rewarding. “Working with people, developing people, helping them grow, motivating them—it’s always fun and challenging,” said Dr. von Simson.
That realization fundamentally reshaped his leadership philosophy.
Blending Veterinary Medicine With Business
Although Dr. von Simson now spends much of his time leading marketing organizations, he still sees himself first and foremost as a veterinarian. “When I’m traveling and filling out the immigration form,” he joked, “I still write ‘profession: veterinarian.'”
That identity influences every business decision he makes. Unlike marketers without technical backgrounds, he understands both the science behind products and the emotional motivations driving Veterinary professionals and pet owners.
“The moment you lose connection to what drives your customers,” he explained, “you cannot be an effective marketer.”
Veterinarians rarely make decisions based solely on financial considerations. Their primary motivation remains improving animal health. Similarly, pet owners often make deeply emotional decisions rooted in the human-animal bond.
Understanding those motivations allows Dr. von Simson to communicate more effectively with both audiences. His Veterinary education also enables him to translate complex scientific concepts into practical benefits.
“I really enjoy bringing new solutions to people who take care of animals,” he said, “and making that message clear and simple.”
Bringing Marketing and Veterinary Services Together
Today, as Head of Marketing and Veterinary Services for Virbac U.S., Dr. von Simson oversees two functions that traditionally operate independently. For him, however, the combination makes perfect sense.
Throughout his career, he has consistently used Veterinary science to strengthen marketing strategy. One example came during the launch of Previcox®, when he helped oversee a 1,000-dog clinical trial. Rather than simply supporting regulatory requirements, the study generated valuable data demonstrating meaningful product differentiation.
“I use the Veterinary function to allow me to do better marketing,” he explained.
At Virbac, integrating marketing and Veterinary Services creates additional advantages. Veterinary teams educate practitioners, sales teams reinforce consistent messaging, and marketing communicates with pet owners. Together, these functions create a unified customer experience.
“We’re in the age of omnichannel messaging,” said Dr. von Simson.
Whether pet owners receive information through their veterinarian, retail channels, or digital platforms, consistency has become essential. That alignment ultimately benefits both Veterinary professionals and the families they serve.
Innovation Driving Better Patient Care
Among the areas generating the greatest excitement for Dr. von Simson are dermatology and parasiticides—two therapeutic categories where Virbac has established significant leadership. He believes dermatology is entering an especially exciting period.
Advances including monoclonal antibodies, JAK inhibitors, and additional emerging therapies continue expanding treatment options for allergic skin disease. However, innovation alone isn’t enough. One challenge concerns him deeply. He sees a widening gap between Veterinary dermatology specialists and general practitioners.
“What I see,” he explained, “is a growing disconnect.”
Specialists possess increasingly sophisticated treatment options. General practitioners, often working under tremendous time pressure, may struggle to remain current while managing shorter appointment times.
Virbac aims to help bridge that gap through education, practical tools, and clinical resources. The company’s goal isn’t simply introducing new products. It’s helping veterinarians confidently apply them.
Parasiticides remain another lifelong passion. Having witnessed revolutionary products like Frontline reshape parasite control early in his career, Dr. von Simson continues following advances closely. Yet he also recognizes an important challenge. As combination products become increasingly sophisticated, they often become more expensive. That creates affordability concerns for some pet owners.
“I think we should have,” he said, “our best-in-class favorite product—but also a Plan B.”
Offering affordable alternatives helps ensure more pets remain protected rather than receiving no parasite prevention at all. For Dr. von Simson, innovation succeeds only when it improves access to care.
That philosophy continues shaping both his leadership and Virbac’s approach to supporting Veterinary medicine.
