Dr. Greg Nutt

Dr. Greg Nutt

Dr. Greg, co-owner of Riverstone Animal Hospital, opened the practice in 2002. He is a graduate of Oklahoma State University in 1996. He is affiliated with the AVMA and Veterinary Honor Society and has completed continuing education hours in rabbit and exotic pet care. His veterinary career path began at a young age, when he and his family bred beagles and rabbits. This experience showed him the importance of the bond that people have with their pets and fastened his resolve to make caring for pets a career.

As a veterinarian, he enjoys sharing his love for his pets with the team and supporting the mission of serving pets and their owners. One of his favorite aspects of his position is witnessing the love that pet owners have for their pets and being able to give these owners healthier family members. He also looks forward to forming relationships and friendships with the people he sees. He goes the extra mile to provide his clients and patients with exceptional care, taking the time to sit on the floor with his them to get to know them while listening to his clients' needs.

Dr. Greg is married to Dr. Simone Nutt, his partner at the hospital, whom he met in college in California. Together, they have three four-legged family members. Beatrice the Beagle, who is Dr Greg’s favorite, Spud the Boston Terrier, and Banjo the cat who was rescued from RAH as a kitten. When he's not caring for pets at Riverstone, he enjoys fishing, kayaking, reading, gardening, camping, and spending time with his family. Although he is passionate about being a veterinarian and helping pets become well, his greatest accomplishment is being a great father.

Dr. Simone Nutt

Dr. Simone Nutt

Dr. Simone is the other half of the husband-wife team at Riverstone Animal Hospital. She graduated from Oklahoma State University and completed continuing education hours in feline medicine, internal medicine, ultrasound, endoscopy, and dentistry. The most notable moment of her career has been realizing the impact that veterinarians can have in enriching the lives of people. She has seen how valuable it is to her clients to find someone who truly listens and cares about how they feel about their pet and someone they can trust with their pet.

With a strong interest in medicine and working to eliminate pain and illness, Dr. Simone considers it an honor to care for pet family members. She also loves being able to work with great pet care team members who share her passion of helping the community care for their pets. As a veterinarian, she welcomes the variety that each day brings and investing in people's lives and form relationships. She loves seeing people every day who love their pets the way she does. One of her many goals is to truly find out what each owner's concerns and goals are and working with them in accomplishing those goals, rather than just treating each pet and client the same way.

Dr. Simone had the privilege of marrying her soul mate, Dr. Greg, and opening the practice with him. Together, they have three pets: A Beagle, a Boston Terrier, and a cat who rules over the dogs. In her spare time, she enjoys horse back riding, kayaking with her husband, reading, serving at her church, and camping with her family. She also loves reading the Bible and considers it a source of joy, as it never fails to be relevant to her daily life.
