Our Team
Dr. Hartfield - Owner/Lead Veterinarian
Dr. Hartfield earned her Bachelor’s degree in Animal Science from Texas A&M University before receiving her Doctor of Veterinary Medicine degree from Oklahoma State University. After graduation, she began her career in mixed animal practice in Cushing, Oklahoma, where she discovered a passion not only for caring for animals but also for mentoring the next generation of veterinarians.
Today, Dr. Hartfield is the proud owner and operator of three rural Oklahoma mixed animal practices—Holdenville Veterinary Clinic, Hartfield Veterinary Clinic, and Lake Area Veterinary Clinic. Through these clinics, she is committed to providing compassionate, high-quality veterinary care to both large and small animals while expanding access to veterinary services in rural communities across Oklahoma.
Her passion for education extends beyond the exam room. Dr. Hartfield is the author of the Dr. Hartfield Book Series, a five-book collection created to teach children about responsible pet ownership while inspiring an interest in veterinary medicine and animal health.
When she's not caring for patients, mentoring students, or writing her next book, Dr. Hartfield enjoys spending time at the lake, water skiing, and riding horses with her husband, Preston, and their son, Paden.
Dr. Stacy is a familiar face to many in the Cleveland area, where she spent years caring for horses and companion animals while building lasting relationships with clients. Originally from the Bixby area, she later established a successful mobile equine practice based out of Bixby, allowing her to serve horse owners throughout northeastern Oklahoma. Throughout her career, her greatest passion has always been equine medicine, and she has developed extensive experience in preventive care, lameness evaluations, reproductive medicine, emergency care, and performance horse health.
While horses remain close to her heart, Dr. Stacy has recently returned to her roots in rural mixed animal medicine, where she enjoys caring for everything from family pets to livestock. She values the variety that mixed animal practice offers and enjoys partnering with owners to provide compassionate, practical care for animals of all sizes.
We are excited to have Dr. Stacy sharing her years of experience, knowledge, and passion for veterinary medicine with our clients and their animals. Her commitment to quality medicine, client education, and personalized care makes her a wonderful addition to our team.
Outside of the clinic, Dr. Stacy enjoys attending barrel races with her daughter, riding horses, spending time with her own pets, and relaxing by the pool with family and friends.

Tara - Office Manager
Many of our clients will recognize Tara as one of the first friendly faces you see when you walk through our doors. She has been a valued member of the Lake Area Veterinary Clinic team since 2017 and plays an important role in helping our clinic run smoothly each day.
Tara is married to her husband, Kelly, and together they have a large, close-knit family that includes five children, eleven grandchildren, and one great-grandchild. Outside of the clinic, she stays busy caring for her three dogs and two cats, as well as helping manage their family cattle farm.
In her free time, Tara enjoys spending time with her grandchildren and traveling whenever she has the opportunity.

Emily has been working alongside Dr. Hartfield for the past six years, gaining experience across all of our clinic locations. Her passion for animal care is evident in every aspect of her work, and she is deeply committed to providing excellent care for both her patients and their owners.
Emily has recently applied to veterinary school and hopes to begin her journey next fall. We are confident she has a bright future ahead and will make an exceptional veterinarian.
Outside of the clinic, Emily cares for a variety of animals, including her dog, Peanut, several horses, and two cats. She also plays an active role in her family’s cattle ranch, further reflecting her lifelong dedication to animal care.
Avery is heading into her senior year of high school and has already become a valued member of our team. She enjoys the opportunity to meet and learn about the many different animals and breeds that come through our clinic each day, making her role both exciting and educational.
Outside of the clinic, Avery is an accomplished vocalist. She and her ensemble partner earned a superior rating at the state choir contest last year—an achievement that reflects her dedication and talent.
At home, Avery cares for a variety of animals, including her dog Sadie, a cat, a rabbit, and a flock of chickens. She has a strong interest in dog training and hopes to pursue a future working with dogs professionally, with a particular passion for supporting the service dog and working dog community.
