Veterinary Services (Coming Soon)

Callie Fogle, DVM DACVS-LA, is an Equine Surgeon, previously on faculty at NCSU-College of Veterinary Medicine. She received her DVM from Louisiana State University College of Veterinary Medicine, and completed her equine surgery residency at NC State.

Fogle’s professional interests center on delivering state-of-the-art care for horses within a collaborative learning environment and providing learning opportunities for veterinary trainees that serve rural community needs. Her research focuses on addressing clinical questions related to gastrointestinal and soft tissue diseases, with the goal of advancing the field of equine veterinary medicine.

In her free time, she enjoys extremely competitive games of kickball with her teenagers, cheering those same teens on at music and athletic events, reading, horseback riding, and running.

Sierra R. Guynn, DVM, PhD, DACVPM, is a food and fiber animal veterinarian who helps producers sustain the health of animals that provide meat, milk, wool or leather. She is passionate about veterinary education, sharing practical skills and knowledge with veterinary and animal science students, producers and industry stakeholders. A strong advocate for rural communities and the veterinarians who serve them, she highlights their vital societal role.

Her research focuses on apicomplexan infectious diseases in ruminants and converting livestock research into actionable strategies for small- and medium-scale producers to improve animal health. She supports the One Health approach and offers a practical livestock perspective to encourage realistic, positive change.

Guynn earned her Doctor of Veterinary Medicine from the Virginia-Maryland College of Veterinary Medicine and her Ph.D. in Comparative Physiology from Creighton University School of Medicine. She practiced large animal ambulatory veterinary medicine for six years in private practice and 13 years in academic practice. During that time, she earned a graduate certificate in Public Health and became a Diplomate of the American College of Veterinary Preventive Medicine.

Outside of work, she enjoys hiking, camping, riding her motorcycle and traveling with her husband.

Ashley Fowler-Brady, BS, LVT, is a Licensed Veterinary Technologist and educator committed to advancing animal and public health through ethical practice, hands-on instruction, and mentorship. With more than 25 years of experience in veterinary medicine, including nearly two decades in academic leadership, she has a strong record of supporting program excellence, student success, and faculty development.

Her clinical background spans small and large animal practice, as well as equine anesthesia. She began as a Veterinary Assistant at Gaffney Animal Hospital, later serving as a Veterinary Technician at Creek Run Veterinary Clinic under Dr. Poag Reid, and as Lead Veterinary Technologist in equine anesthesia at the University of Tennessee. In these roles, she contributed to medical, surgical, anesthetic, and theriogenology procedures while developing leadership and management expertise.

Fowler-Brady has served as an Instructor and Department Head in an AVMA-accredited Veterinary Technology Program, where she provided hands-on instruction, mentored students and faculty, and promoted critical thinking, professional competence, and lifelong learning.

She holds a Bachelor of Science in Animal Health Technology and Equine Science from Murray State University and an Associate in Health Science in Veterinary Technology from Tri County Technical College. She is dedicated to fostering inclusive and respectful learning environments aligned with Clemson University’s values of integrity, respect, and service.

Dr. Shawn Williamson was born and raised in Rock Hill, South Carolina. He earned a Bachelor of Science in Animal Science from Clemson University, where his work at the Clemson University Equine Research Center sparked his passion for equine breeding, reproduction and management.

He received his Doctor of Veterinary Medicine degree from the University of Georgia in 2006 before joining Mountain Animal Hospital in Weaverville, North Carolina. In 2008, he relocated to Mocksville, North Carolina, to practice at Davie County Large Animal Hospital, where he spent five years developing expertise in equine lameness, podiatry and sport horse medicine.

In 2013, Dr. Williamson returned to Weaverville and founded Asheville Equine Mobile Veterinary Service. The practice grew under his leadership from a mobile service into a three-veterinarian team and, in 2025, opened a dedicated hospital facility to better serve the region's equine community.

Dr. Williamson joined the faculty of the Harvey S. Peeler Jr. College of Veterinary Medicine at Clemson University in July 2026 as part of the Large Animal Ambulatory Service. Returning to his alma mater, he combines decades of equine practice experience with a passion for educating future veterinarians while continuing to provide high-quality care for horses across South Carolina.

If you ask Dr. Michal "Callie" Benoit when she decided to become a veterinarian, she'll tell you it started long before veterinary school. Growing up in a small town in upstate New York, she spent her childhood around horses; riding, showing in 4-H, helping her grandmother at the barn, and eagerly tagging along with the local large animal veterinarian. Watching "Doc" care for both animals and the people behind them sparked a dream that never changed.

That dream led Benoit to Cornell undergrad then to NC State University College of Veterinary Medicine and, eventually, to Virginia, where she spent nearly 20 years building and owning a rural equine practice. She has treated everything from newborn foals to emergency colic cases, often with a truck full of equipment, a cup of coffee, and a GPS that occasionally questioned her life choices.

While Benoit loves practicing veterinary medicine, what truly energizes her is teaching. She has mentored veterinary, technician, and pre-veterinary students, welcomed countless ride-alongs, and encouraged young people through 4-H and agricultural programs. Nothing makes her prouder than watching former students become colleagues, especially those returning to serve as large animal veterinarians in rural communities.

As a faculty member at Clemson University's College of Veterinary Medicine, Benoit is excited to help build something special. She hopes to prepare students to become not only excellent veterinarians, but also trusted neighbors, compassionate mentors, and lifelong advocates for animals, agriculture, and the communities they serve. And if a few students leave with muddy boots and a newfound appreciation for large animal practice, she'll consider that a bonus.
