Dr. Amy Tongue
Owner and Veterinarian
Amy grew up in the San Francisco Bay area and received her undergraduate degree in Animal Physiology from UC San Diego. She graduated from veterinary school at the University of California, Davis and spent the next three years at a practice in rural Northern California working on a large variety of large and small animals where she solidified her love of all things furry, including horses.
After meeting her future husband, a Lake Oswego native, and joining him in Oregon in 2002, Amy began practicing in Lake Oswego. She and her husband, Tom, have two boys, an adorable rescue dog named Piper, and random foster dogs or cats at any given time. Amy’s medical interests lie in surgery and general medicine, though she enjoys all the diversity that veterinary medicine has to offer. In her free time, she enjoys exploring the Oregon trails, reading, and gardening.
Dr. Deb Ward
Dr. Ward was born and raised right here in the Pacific Northwest, in Salem. She obtained both her Bachelor degree in Veterinary Science and her doctorate degree in veterinary medicine from the University of California, Davis. She moved back to Oregon to practice medicine and to raise her family.
Besides her husband and three cute kids, her family includes an Arabian horse, two dogs (a pit bull mix and a Chinese crested), one calico cat with extra toes, and a blue-fronted Amazon parrot.
She enjoys small animal medicine and has been treating small exotics and avian species for the last 16 years (those pets with fur or feathers). In her rare leisure time, she enjoys hiking, travel, kayaking in flat water, and reading. She also volunteers at a local elementary school.

Dr. Melanie MacClanathan
Dr. MacClanathan began her relationship with OVH in 2014 as a Veterinary Assistant and it was clear from the beginning that she had a calling to be a veterinarian.
Melanie is now a graduate from Oregon State University with a special interest in surgery, ultrasonography, nutrition, and behavior. She is excited to continue the relationships she has formed with OVH clients and patients in years past, and looks forward to building many more.

Dr. Kylie Nomi
Dr. Nomi was born and raised in Beaverton, OR. She decided at the age of 5 that she wanted to be a veterinarian and has stuck to that plan ever since. She graduated with a B.S in Biology from Linfield College in McMinnville, OR, and graduated with her Doctorate of Veterinary Medicine from Oregon State University.
Kylie’s clinical interests include surgery, exotics, and behavior, but she enjoys all aspects of clinical practice. Outside of work, she loves hiking and camping around the Pacific Northwest, crafting, and reading.
Kylie’s family includes her husband Zakk and their rambunctious cat, Pudge. They are hoping to add more cats and dogs to their menagerie once they are able to buy some property and aim to have a hobby farm in the future.
Jessie Merritt CVPM, SPHR
Jessie was one of those children who seemed to gravitate to animals from the day she was born. Bringing home “stray” animals and nursing injured wildlife was a routine part of her childhood.
Since Jessie has held almost every position in the profession, she believes it offers her a valuable insight and perspective of team life in the trenches that has enhanced building successful relationships with her team and peers. In 2009 she became a Certified Veterinary Practice Manager and in 2013 she earned her SPHR certification.
Jessie is active within one of the most well respected professional veterinary organizations for management called the Veterinary Hospital Managers Association. Jessie also enjoys participating in various veterinary social networks in addition to helping facilitate the monthly meeting and general organization of a group of local Practice Managers whose insight, wisdom and wit she greatly admires.
Personally, she spends her time on her country property tending the garden, chickens, and turkeys as well as one Giant Schnauzer “Cajun” (an 80-pound juvenile delinquent) and “Hazel,” the Caucasian Ovcharka (the princess of the group), a herding dog mix rescue named Tucker, “Cowboy” the Australian Cattle Dog, and the baby of the group is “Dutchman” another Caucasian Ovcharka.
If you ask Jessie about life, she will say, “One of the things that will always bring me my greatest sense of fulfillment is spending my days working side by side with people I truly admire, that share the goal of helping our clients take the best possible care of their much-loved pets. All of that and puppy breath too – it doesn’t get much better than that!”

Courtney currently has two mischievous kitties named “Hy -Purr” and “Spaz” and the newest addition to the family is “Davis”, her not so brave Chihuahua mix. Just don’t tell Davis since he thinks he is very brave.

Courtney’s main professional goal is to continue to expand her knowledge base in the field and continue to offer the excellent patient care she is known for.
Outside of work, Courtney enjoys family time with her husband Dan. She can also be found painting and drawing or relaxing with friends and family. In January of 2014, Courtney and her husband welcomed their first two-legged child into the world, and her name is Hayden.

Malissa loves being part of a team that is positive and patient-focused, where she can treat every animal with compassion and where she can take the time to get to know a pet before working with them.
