ABOUT US
One radiologist.
And the team behind her.
It takes one board-certified radiologist to read complex imaging. It takes a team to run a practice the right way. These are the people who answer your call, prep your pet, run every scan, and follow up on every report.
Dr. Jennifer L. Johnson-Neitman
DVM, DACVR, OVDI Founder & Owner
Your pet’s specialist
Dr. Neitman is a 4th-generation Oklahoman who came home after years in academia and private specialty practice. She started OVDI to do veterinary radiology the way she'd want it done for her own pet: every scan read personally, every case followed through, every owner walked through what's on the screen. She loves to teach. And she'd rather find the answer than guess at it.
For more than eleven years, Dr. Neitman has been doing mobile radiology across the Oklahoma City metro — driving from clinic to clinic with a console ultrasound in tow.
In Winter 2026, that work will get a permanent home in Edmond: a dedicated specialty facility with the only 128-slice CT for pets in Oklahoma, in-house bloodwork and triage, outpatient X-rays, endoscopy, and nuclear medicine for I-131 treatment, with MRI following shortly after.
She works alongside a team of certified vet technicians and care coordinators, plus a network of board-certified specialty consultants for cases that need more than imaging.
Dr. Neitman’s love for animals extends to her furry family at home:four rescue guinea pigs named Furious Peanut Unicorn, Rockin' Pickles Pineapple, Rumblin' Rolo, and Mighty Reese's. Two rescue dogs, Lazy Daisy Grace, a beagle, and Tickles the Hairy Monster, a terrier mix. Two English Lab puppies, Jemma Jean Midnight Pearl and Phoebe Easter Munchkin. And Fred, a Red-Lored Amazon parrot she's had since she was eight, who turned out to be Freda, discovered via DNA sexing in vet school.
Outside the practice, she's most likely outdoors with her family, camping, hiking, fishing, or photographing landscapes in the National Parks. At home she reads, watches old movies, and listens to 80s and 90s music while spoiling the menagerie.

RVT & Patient Care Lead

At OVDI she's the voice on the phone with pet owners and referring vets, and the person who keeps each handoff clean. Empathy is her throughline. She treats every pet like her own. After her first child, Alyssa stepped back from hands-on technical work to focus on client and referral coordination.
At home: a dog (Pups), a cat (Mr. Lo Mein), and a green-cheek conure (Mentor).
Tech Assistant & Referral Coordinator
Alyssa Preston
Hannah Lampson has been a veterinary assistant since 2018. She's drawn to vet med for its unpredictability — no two days look the same — and the chance to be in animals' corners through every appointment.
At home in Blanchard, Oklahoma: a husband, two kids, three dachshunds, several goats, and a flock of chickens, on a small farm she runs alongside the day job.
