Dr. Rocky M. Mason, DVM, Founding Partner and Owner

Dr. Rocky Mason grew up on a small cattle and sheep farm in the far eastern panhandle of West Virginia in Summit Point, about 60 miles from Washington DC. During his childhood, Dr. Mason worked closely with his grandfather, both on the farm and at his professional employment with White Veterinary Supply. “My grandfather was a bastion of hard work, honesty and integrity,” Dr. Mason says. “He taught him the value of hard work and aggressive effort. ‘If a job was worth doing, it was worth doing it right’” was a mantra he lived by.

Becoming an equine veterinarian was a shared dream between Dr. Mason and his grandfather. Dr. Mason received a BS in Animal and Veterinary Sciences (Pre-vet) in 2002 from West Virginia University before attending the University of Georgia College of Veterinary Medicine, where he received his Doctor of Veterinary Medicine (DVM) in 2006.

I have always been amazed at the bond between humans and animals, and cherished the thought of having an important role in bolstering that relationship,” he explains.

Dr. Mason is a founding partner of Lexington Equine Medical Group, where he has a special interest in perinatology, advanced reproduction (the management of breeding stallions and mares), internal medicine, preventative and herd health, and performance horse medicine and lameness. Dr. Mason provides care for everything from racehorses and polo ponies to eventers, gaited mountain horses – and everything in between.

When asked about his favorite thing about working in the Bluegrass, Dr. Mason said that the plethora of horses here afford him the opportunity to call on and use his knowledge, experience and training in a variety of ways. “Because of the vast case load, I get to treat the uncommon cases commonly!” he explains.

Dr. Mason grew up riding cow horses and competed in youth team penning. He has several family members who trained Thoroughbred racehorses, so he had exposure to the industry early on. He currently owns some Thoroughbred breeding stock (mare and foals) and he’s in the perpetual dream market for a polo horse, a foxhunter and a cow pony.

Outside of work, Dr. Mason enjoys being outdoors; he competes in ultra endurance events (running, biking, kayaking, Ride & Ties) and enjoys traveling, fly fishing, upland bird hunting and backpacking. He also has a classic 1970 Ford Bronco and enjoys motorsports.

Dr. Mason is married with two daughters, Addison(13) and Ainsley (12), and one four-legged daughter, Molly (7), a German Shorthaired Pointer who can be found sleeping in the back seat of his truck most days.

Dr. Mason sits on the Kentucky Horse Council Board of Directors and is the chair of the Equine Health and Welfare Committee. He’s co-authored a paper published in the Journal of Veterinary Dentistry and has presented at the American Association of Equine Practitioners convention. He is also part of the Breeders’ Cup Treating Veterinary Team and is licensed in Kentucky, California, New York, and Florida.

Dr. Chris R. Smith, Founding Partner and Owner

Originally from Corsicana, Texas, Dr. Chris Smith attended Texas A&M for both undergrad and vet school.

Dr. Smith enjoys “being able to see successes from conception to birth to the racetrack and hopefully to the winner’s circle, but most of all being able to make a difference in the lives’ of animals,” he explains. “The relationships created with the owners and managers along the way – it’s as if they are family.” Dr. Smith has been involved directly and indirectly with several of the winners of Triple Crown races.

He’s grateful for the professional horseman in the industry and the quality of stock he gets to see. “The centralized location for all farms that Lexington offers requires less time in the truck and more time to be a vet,” he explains. “The roads we travel and farms we are on daily are beautiful and not taken for granted.”

Dr. Smith team roped a bit through high school, and he’s been involved in the Thoroughbred business with mares, foals and yearlings. He currently doesn’t own any horses, but does have one pony named Rooster his daughters hop on from time to time.

Dr. Smith is married with two daughters; he enjoys spending time watching his kids in their various sports activities, along with hunting, fishing, hiking and the outdoors.

Dr. Patrick J. Ford, Founding Partner and Owner

Dr. Patrick Ford arrived in the Bluegrass via Western Pennsylvania, where he completed his undergraduate studies at Washington & Jefferson College and then attended the University of Pennsylvania School of Veterinary Medicine.

Dr. Ford is a founding partner of LEMG who is particularly passionate about equine reproductive medicine, though he loves all aspects of practice in Central Kentucky. His favorite thing about working in the Commonwealth is the natural beauty of the land and the horses the land produces.

Dr. Kandace B. DeBolt, Associate Veterinarian and Import & Export Coordinator

Dr. Kandace Brooke DeBolt is an Alabama native who attended Auburn University for both undergrad and vet school.

Dr. DeBolt joined the LEMG team in 2019 as an import/export specialist. With so many horses in the Commonwealth traveling overseas to race, compete and breed, Dr. DeBolt’s knowledge is key to ensuring each horse arrives with all its paperwork, testing and other protocols in place.

Dr. DeBolt’s love of animals was fostered by her parents; her father is a small-animal veterinarian whom she grew up working with on their 40-acre farm. “I developed a deep love for taking care of animals [on the farm],” she says. “I loved the animal-care aspect, but I also loved helping owners care for their pets. Watching my father as a valuable member of our community was inspiring, too.”

Dr. Debolt rode on her family farm and moved into hunter/jumper competition as a teenager. In college she began eventing, competing mainly on Thoroughbreds. “I currently have a mustang that is showing a lot of promise as an eventer, if I can ever find time to ride him!” she says. “My kids enjoy our pony sporadically when time away from other sports permits.” Dr. DeBolt also owns two miniature donkeys.

When not working or riding, Dr. DeBolt enjoys hiking, running, reading, kayaking and canoeing, time with her family and her animals, and anything outdoors. Her family includes four boys, ages 11, 8, 6 and 4, and a husband “who is my partner in running this circus” she says.

One of Dr. DeBolt’s favorite things about Lexington is its beauty, as well as the ability to have land, yet still be close to the city – a far cry from San Francisco, where she lived before. Also important to her is the sense of camaraderie, both equine and otherwise: “We have found a community here full of great friends” she comments.

I enjoy lacerations. I enjoy anything that makes you think a little extra.”

Her favorite cases are those that are a challenge, but that are resolvable. “I love when a nasty laceration comes together well; I love the dystocia that I can get fixed; I love the dummy foals that turn around; I love the abscess that pops and gives instant relief,” she explains.

Dr. Mauk loves living in the Bluegrass. “I have so much respect for the athletes that we create here and I have enjoyed working with them at different stages throughout both their careers and mine,” she says. “With that said, I think my favorite part about working in Central Kentucky is the hope. There is so much potential in each new foal, with each sale, with each new stallion. It’s so exciting to follow these horses and hope for their success.”

Dr. Growette really enjoys reproduction and foal medicine; she has recently become interested in sales work, as well. She’s particularly fond of working in the Bluegrass for a plethora of reasons, among them “the landscape, the prestige of the industry as a whole and the unique opportunities available to me simply by practicing veterinary medicine in this area,” she explains. “I love driving through the rolling countryside and seeing beautiful and historic horse farms everywhere, and getting to participate in events [either as a veterinarian or a spectator] like the horse sales and race meets. I love that so much of the way of life in the Bluegrass surrounds the horse. The bourbon isn't too shabby either!”

Dr. Jessie George , intern

Dr. Jessie George grew up on a cow calf operation in Salt Rock, West Virginia, where she learned to treat and care for sick animals from an early age. It’s no surprise that Jessie decided to pursue veterinary medicine: “I always found joy in healing the sick and therefore pursued a career that would allow me to do just that each day,” she explains. “Patient care is one of my favorite aspects of being a vet because you are the biggest advocate for your patient and have the ability to help them when they can’t help themselves.”
