Meet The Equine Veterinary Staff

Dr. Sally Vivrette, Practice Owner


Dr. Vivrette is a graduate of the University of California at Davis College of Veterinary Medicine. She completed an internship at Cornell and a medicine residency at UC Davis, and went on to be Board Certified in Veterinary Internal Medicine.

After a few years in equine private practice, Dr. Vivrette returned to UC Davis and completed a PhD in Comparative Pathology concentrating on equine reproduction. She moved to North Carolina in 1995 and was head of the Veterinary College's Field Service program until 2000. She received the Norden Distinguished Teaching Award and the North Carolina Horse Council Distinguished Service Award in 2000. Dr. Vivrette started Triangle Equine in 2001 to provide horses and horse owners in central North Carolina with outstanding care of performance and pleasure horses. She strives to include the horse owner, horse trainer and farrier as parts of the team to improve horse health and athletic performance. Her experience with both English and Western competition horses allows her to understand the problems with, and therapies available for, performance horses. She brings a special touch to equine practice with expertise in internal medicine, reproduction and preventive medicine.  Dr. Vivrette is a FEI licensed veterinarian.  This allows her to help you with horse show competition and medications rules.

"I was raised in Northern California.  My family moved to Central California on my 13th birthday.  I was given one present – a brand new horse halter and lead rope.  It was green. I stopped complaining about having to leave my friends behind.  I got into the car – something wonderful was about to happen.  Within a couple of months we purchased my first horse – a quarter horse mare that I named “Rita”. For several years my dad and I went to 4H gatherings, horse shows and gymkhanas. I remember when I won my first ribbon. It was 5th place in barrel racing.  My dad and I hugged each other and cried with joy. Owning a horse and participating in 4H sparked my interest to become a veterinarian."

Dr. Vivrette is Board Certified in Veterinary Internal Medicine.  What does that mean for me and my horse?  Learn More

Dr. Jennifer Patterson, DVM, Certified Animal Chiropractor

Dr. Jennifer Patterson, a local native, grew up in Apex showing her horses on the local hunter circuit. She completed a bachelor’s degree in Biology in Lynchburg, Virginia.  She then worked as an assistant trainer at a busy hunter/jumper barn in Virginia before returning to Raleigh to pursue and complete her veterinary degree at NCSU. She then completed a highly competitive formal internship at NCSU where she gained experience in all aspects of equine medicine including emergency, surgery, and ophthalmology. Additionally, she played a major role in the education of the senior veterinary students. Many of you may have met Dr. Jenn when she cared for your horse at NCSU equine hospital.  Also Dr. Jenn has worked with Dr. Sally Vivrette for 14 years!  She was first a client of Triangle Equine and then a valued veterinary assistant, Dr. Sally’s right hand.  She and Dr. Sally have similar philosophies about horse health and client education.  Their combined horse experience and veterinary training will provide truly comprehensive care for you and your horse.

"Being a horse owner myself, I understand the joy horses bring to our lives and how unique the bond is that we share with them.  I love working with the many different players in a horses team to ensure they get the support they need to have successful careers and enjoy the best quality of life.  It is an honor to be able to work with remarkable animals and the people that care for them."

Lisa Kim, Office Manager

Lisa joined Triangle Equine in the summer of 2015, but has been a client and friend of Triangle Equine since 2001.  She graduated from the University of California at Davis with a BS in Zoology. After a successful career as a pharmaceutical chemist, she took a short hiatus to raise a family.  She is a life long equestrian competing in hunter/ jumpers, dressage,
and a teeny tiny bit of evening.  She lives in Apex with her husband, two daughters, a fluffy collie, and a fat cat. 

"I love helping clients with all of their needs.  I still can't believe I get to spend my day talking about horses."


Debbie Frank, Registered Veterinary Technician

Debbie first met Dr. Vivrette in California in 1985 through her own veterinarian. Needless to say they became good friends and have been ever since. Debbie is an experienced registered veterinary technician who has worked at both the U.C Davis College of Veterinary Medicine and N.C. State College of Veterinary Medicine. She recently retired after 21 years of working in both the Small and Large Animal Hospitals, but found she couldn't stay away from vet medicine. We are pleased that she is now working for Triangle Equine alongside her lifelong friend. She’s thoroughly enjoying meeting all the clients and their fur babies both large and small. She is especially partial to Australian shepherds and currently has two.


Morgan McCallum, Veterinary Assistant

Morgan joined the Triangle Equine team in September of 2020.  Prior to that, she was a working student at a busy dressage and eventing farm. She has also taught beginning riding lessons as a summer camp counselor. Morgan has never settled on a specific riding discipline, rather preferring to take lessons from trainers all over the map and enjoys riding just for fun.  She is a graduate of the UNC Chapel Hill class of 2019.  She proudly owns one very spoiled cat named Odette.
