Tulsa OK Veterinarians Ron Hooley, DVM

Dr. Ron Hooley is a general practitioner with advanced certification in Canine Rehabilitation and a co-founding veterinarian of River Trail Animal Hospital. He has been practicing veterinary medicine since 1989.

A native of Enid, Poteau, and then Edmond, Oklahoma, Dr. Hooley says his family was among the original Oklahoma homesteaders during the Land Run of 1889. "I spent summers working on my family's farm in the panhandle of Oklahoma, where I developed a love of caring for and treating the animals," he says. "In high school, I began working for a veterinary practice in Edmond. I spent most of my days in the kennels taking care of pets, but loved being around the veterinary practice. I eventually advanced to veterinary assistant in the hospital and spent time assisting in surgery. I felt then that I had found my true calling and began my efforts to go to veterinary school."

For his undergraduate studies Dr. Hooley attended Oklahoma State University where he worked for all four years in the Animal Nutrition Department as a laboratory assistant and earned Honor Roll every semester. In 1985 he graduated with a Bachelor of Science in Animal Science. Later that year he entered Oklahoma State University's Center for Veterinary Health Sciences. He graduated with a Doctorate of Veterinary Medicine in 1989.

Dr. Hooley's areas of professional interest include internal medicine and gastroenterology. In 2009 he earned accreditation in Canine Rehabilitation. Now that he's a veterinarian, Dr. Hooley says, "Just like the first week I ever walked into a veterinary office, every time I go into the clinic I'm excited to see all the patients and their owners. I love the happy patients I get to see every day."

Dr. Hooley's personal interests include riding road and mountain bikes as well as sailing, scuba diving, aquarium reef keeping, and camping.

Tulsa, Bixby Veterinarians Roddy Roberts, DVM

Dr. Roddy Roberts is a general practitioner and a co-founder of River Trail Animal Hospital.

A native of Tulsa, Dr. Roberts says, “I grew up in a mixed rural/urban environment, but I was always outdoors. I also spent some summers with my grandfathers – one had a farm in Texas and the other a ranch in Colorado – I spent quite a bit of time around livestock as well as our many household pets, which made it seem like the natural thing to want to spend my life around animals and caring for them. From wildlife to the family companion, animals made me want to be part of that.”

Dr. Roberts attended Oklahoma State University for his undergraduate studies where he earned a Bachelor of Science in Biomedicine in 1982. In 1986 he graduated with a Doctorate of Veterinary Medicine.

Dr. Roberts’ areas of professional interest include allergy, internal medicine, and surgery. He also holds postgraduate training in hepatic and pancreatic diseases. Now that he’s a veterinarian, Dr. Roberts says, “I really enjoy striving to make the life of your pt the healthiest and happiest it can be. I love continually learning and growing as a veterinarian. The trust you give me is one of the greatest gifts I can receive.”

He and his wife Joanie have two daughters named Miranda and Hannah, both are married, and a son named Boone. The family also has a mixed breed named Finn.

Dr. Roberts adds, “My deepest drive is to serve God and others as a Christian man.” When Dr. Roberts isn’t at River Trail Animal Hospital he is in his wood and metal shops and here lately he has been working on building a ‘hotrod’ truck!

Tulsa OK Veterinarians Amy Copeland, DVM

For as long as she can remember, Dr. Copeland's mother (a former veterinary technician) instilled a love of animals and medicine in Dr. Copeland in their Yukon, Oklahoma home. From a young age, she knew that she wanted to be a veterinarian, but was afraid that certain aspects of veterinary medicine would be emotionally difficult.

All this changed in high school when her family took in a puppy named Rocky whom, unbeknownst to Dr. Copeland and her family, had serious health issues. She and her family worked closely with their veterinarian to treat Rocky, but he unfortunately passed away. The heartbreak Dr. Copeland felt was accompanied with a surprising sense of peace. She knew they had done everything humanly possible, had alleviated Rocky's pain and suffering, and had given him a wonderful (albeit short) life. This eventually gave her the push to become a veterinarian. Her earlier fears were silenced as she learned that there will be sad times and that she will not be able to cure every patient, yet there will always be something that she can do to help every animal she meets and their humans as well.

After high school, Dr. Copeland attended the University of Oklahoma where she received her bachelor's degree in zoology. While an OU, Dr. Copeland was an Oklahoma State Regents' Academic Scholar and an OU President and Dean's Honor Roll student. For her academic excellence, she was acknowledged by the National Society of Collegiate Scholars and the Golden Key Societies. After her undergraduate studies, Dr. Copeland went to Oklahoma State University College of Veterinary Medicine where she earned her Doctorate of Veterinary Medicine in 2011. While at veterinary school, she was on the OSU Center for Veterinary Health Science President and Dean's Honor Roll.

Dr. Copeland is a "self-described nerd." She enjoys embracing the challenge of learning new things in order to keep up with the ever-evolving and improving field of veterinary medicine. She says, "It is never dull and I get to practice such a broad spectrum of medicine from pediatrics, geriatrics, wellness, surgery, emergency, endocrinology, radiology, ultrasonography, and so much more." Her intense curiosity comes with the added benefit of meeting a variety of interesting, caring pet owners and their equally amazing, loving and entertaining fur children along the way. Dr. Copeland's greatest professional veterinary interests are dermatology, pediatrics, geriatrics, internal medicine, and wellness & preventative medicine.

Dr. Copeland and her husband Brock share their home with their children Joslyn and kai, a pit bull named Loki, a Catahoula mix Artmeis, and a grey cat Horace. In her free time, Dr. Copeland enjoys swimming, reading, playing with her kids, going to the movies, traveling, and scuba diving. Her favorite hobby is aerial circus arts, including silks, lyra, lillipop, and pole.

Tulsa OK Veterinarians Eryn Ayres DVM, CVA

Dr. Erin Ayres born and raised in Oklahoma; Tulsa was an obvious place for her to land. Early on Dr. Ayres’ love for nature and animals was obvious, and though her first dream of “being a dog when she grew up” passed her by – being a veterinarian was a close second.

After receiving her biology degree from Oklahoma Baptist University, Dr. Ayres moved to Stillwater with the intent of pursing her Doctorate in Veterinary Medicine from OSU CVHS. Having worked at SeaWorld, and with a passion for large exotics, she started her veterinary career with her sights set on marine mammal medicine. Although this is still an area close to her heart, she couldn’t deny the pull of being an advocate for the four-legged members of the family (and Oklahoma is seriously lacking in oceans). From that point forward, she dove headfirst into the world of small animal medicine.

Dr. Ayres’ professional interests include integrative medicine, traditional Chinese medicine, food therapy, pain management, and geriatric medicine. She is a Certified Veterinary Acupuncturist and is currently pursing certification in food therapy.

At home Dr. Ayres has two rescue pups – Penny, a parvo patient she got a little too attached to, and Bruno, a Bernese mix. When not in the clinic Dr. Ayres enjoys spending time with her daughter Ivy, ceramic and glass work, spending time outside, and finding any excuse to get back to the ocean.
