Joellyn Herriman
Certified Veterinary Technician

Joellyn grew up in La Grande, OR. She went to Eastern Oregon University and received her Bachelor’s in Agricultural Business Management through OSU. While there, she was on the Collegiate Polo Team all 4 years. After graduating, Joellyn spent a year in Kentucky working on a thoroughbred horse farm and working at Hagyard Equine Medical Institute. These experiences spurred her into pursuing a degree in Veterinary Technology through Yakima Valley Community College. Joellyn joined the OTVC family in 2011. In her off time, Joellyn, her husband and 3 boys, enjoy white water rafting, hunting, horseback riding, and volunteering at their church. She is an up and coming chicken farmer and has earned the title of pollo loco.

Jessica Kooch

Jessica is from Wallowa county and her passion in the veterinary field began on the family farm where they raised pigs, cows and Clydesdales. Her family moved to Umatilla county when she was young while her mother pursued her nursing career. She started her veterinary career in Pendleton but found her “home” at OTVC. She is working hard on her Technician Certification and hopes to graduate from the program soon. In the clinic she is dubbed the “cat whisperer” as she has a unique way with some of our most timid feline patients. She enjoys spending time with her own cats (one plays fetch!), crafting, camping and spending time with friends and family.

Leandra Diorio

Leandra joined OTVC in 2021 with a background in customer service and enjoys being able to help people and their pets. Leandra grew up the biggest animal lover and she and her grandmother would often help give strays a home. Animals have always been a big part of her life, from mice and dogs to cows and horses. She loves them all and aspires to be their hero when no one else will or can. Leandra and her husband have a number of pets that are like their children. When she's not helping a client she can be found painting, drawing or occasionally going horseback riding.

Jakki Long
Senior Receptionist

Jakki Long was born and raised in Hermiston, OR. She has always had a passion for helping animals. Growing up, she was often taking in stray dogs and cats, pet sitting for neighbors, and helping her family breed and raise Labrador Retrievers. She always knew she wanted a career in veterinary medicine and in 2006 she got an opportunity to fill an internship position at OTVC. Afterwards, she was trained to be a veterinary technician. In December 2009, she took on a new position as our receptionist and that’s where she really found her place. As a mother of two, Jakki enjoys spending time with her family from kayaking and fishing to swimming and bbqing. “Being OTVC’s receptionist is the best job in the world! I love being able to interact with not only the pets, but their owners as well and build some wonderful relationships that I will always cherish.”
