Dr. Amy Tongue
Owner and Veterinarian
Dr. Tongue has been a doctor at OVH since 2005, and then in 2010 she purchased OVH and is continuing our heartfelt tradition of medical excellence, extraordinary client service, and a deep appreciation of the human-animal bond.
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 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, three young and mischievous cats, 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.
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.
Melanie lives in Lake Oswego with her husband Michael, their big man cat Max, an adorable Golden Retriever-Husky named Wall-e, and a most handsome Siamese mix youngster named Kuzco. Dr. MacClanathan and her husband welcomed their first child into the family in 2020.
Dr. Kylie Nomi
With OVH since 2020
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 two rambunctious cats, Pudge and Sam. 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.
Dr. Ashley Koomalsingh
With OVH since 2022
Dr. Koomalsingh was born and raised in southern California. She earned her Bachelor’s in biology from Brown University, her Master’s from Drexel University, and her Doctorate in veterinary medicine from Western University of Health Sciences.
After many opportunities to practice all over the country including New York, Los Angeles, and Seattle, she and her husband are happy to call Lake Oswego home. While she enjoys all aspects of veterinary medicine, she has special interests in internal medicine, oncology, and surgery.
Dr. K and her husband Kevin are raising their ever-growing family of young kids and pets (currently one dog and 3 cats). The little ones take up the majority of their “free time,” but they all enjoy exploring the beauty Oregon has to offer whenever they can.
Jessie Merritt CVPM, SPHR
With OVH since 2002
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.
She spends her time on her country property tending the garden, chickens, turkeys, goats, and mules. She also has four dogs including “Hazel” the Caucasian Ovcharka, a herding dog mix rescue named Tucker, “Cowboy” the Australian Cattle Dog, and the baby of the group, “Dutchman” another Caucasian Ovcharka. She and her riding mule Moses, have covered many miles in both Washington and Oregon backcountry.
Lead Client Care Coordinator
Stephanie grew up in Southern Oregon and acquired a love of animals from her father who is now a retired wildlife biologist. Stephanie began working with animals before she was out of high school, pet-sitting for neighbors, working with horses and goats, and volunteering at a local animal shelter. After high school, she moved on to the University of Oregon where she received a Bachelor’s degree in Women and Gender Studies in 2008. While in Eugene, she took up horseback riding on the UO Equestrian Team.
Upon moving to Portland in 2005, Stephanie started working at a local doggie daycare facility as well as entering a working student program with a horse trainer at a hunter/jumper equine facility. After a couple years, she entered the veterinary field and fell in love with the opportunity to develop relationships with pet owners and their companions.
If she’s not at work or at the barn riding her horse Olivander, she is spending time with her husband Alex and their two playful Pit Bull Terriers Zero and Chance. She enjoys walking around Portland, hiking, or just lounging around the house.
Client Care Coordinator
Amy was born & raised here in Oregon all her life. She was fortunate that her mother worked at veterinary clinics as well, so she tagged along as a young girl & got hooked.
Amy owns 12 acres where she breeds and shows her Miniature Horses. She also has goats, and donkeys, and if that isn’t enough, add two scampering dogs: Feather the Italian Greyhound, and River, the baby of the family, an English Springer Spaniel.
Ashley was born in beautiful Palm Springs California and grew up in Las Vegas Nevada.
She studied animal science at Texas A&M and has a lifelong love of animals, which lead her naturally into veterinary medicine. Ashley is currently in school with the goal of attaining her veterinary technician certification.
Ashley has one adorable dog named Zelda, whom she adopted in College Station Texas.
In her spare time Ashley enjoys watching her stories (you’ll need to ask her about that), enjoys the Portland food scene while chasing the occasional sunshine, and she has mad crocheting skills!
Ashley’s passion for animals doesn’t stop at OVH; she volunteered at the at Maetaeng Elephant Park in Chiang Mai, Thailand for 6 months, The Oregon Zoo for 1 year, and has hopes to continue working with wildlife in the future.
Courtney was raised with animals and remembers them as always being an integral part of the family. 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 came to us with a heart filled with compassion and an appreciation for the human-animal bond that we all share. She states, “It has truly been a great experience being able to work with the animals and build relationships with their human companions, our clients.”
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.
With OVH since 2017
Melissa grew up in a small town in southern Michigan and knew from an early age that she wanted to work with animals. She graduated from Northern Michigan University in Marquette, MI with a bachelor’s degree in Zoology and then moved to Portland in February of 2017. She plans to attend a Veterinary Technician program to become a CVT.

With OVH since 2020
Makenzie was born and raised in Portland Oregon, and has wanted to work with animals since she was 4 years old. Makenzie enjoys all species under the sun (and water) but is especially drawn to dogs, aquatic species, and zoo animals. She began her career in veterinary medicine as a volunteer veterinary technician assistant when she was 13 years old. She was eventually hired on at the same practice and promoted to a veterinary assistant, and she knew veterinary medicine was her calling. She has dabbled in dog training but remained dedicated to our profession and has worked in specialty and emergency medicine, and now OVH is thrilled to have her on our team.
Makenzie’s eventual professional goal is to become a Certified Veterinary Technician.
Makenzie’s 4 legged family members include Kiku, a young German Shorthaired Pointer and Sherman, and even younger Rottweiler, and those two make certain she is never bored.
As a testament to Makenzie’s love of aquatic life, she keeps a 55-gallon fish tank and would like to add even more. She loves to go on adventures to the beach with Sherman and Kiku whenever she can. Makenzie also adds rock collecting and archery to her pastimes.
If you ask Makenzie what she loves most about veterinary medicine and OVH, she will tell you that helping any and all animals that need help is one of the best feelings in the world and that the people here at OVH are like family, not just a team.
Makenzie quirky fact? She loves birthday cake!
With OVH since 2019
Sara was born in Washington but was raised in Portland, Oregon. She began her career in Veterinary medicine in 2006 when her own dog developed a seizure disorder that was challenging to manage and heartbreaking to watch. Throughout Sara’s career and growth, she discovered her love of working with pet parents. Working and teaching owners about puppy training is a big passion of hers and she is amazing at it!
Sara and her husband and two children live in Milwaukie with their mini “farm” of animals including dogs, cats, and chickens! She hopes to dabble in some friendly agility course competition someday when time allows. In her spare time, Sara and her family can be found camping and spending time kayaking our beautiful lakes and rivers.
Sara’s philosophy is that veterinary medicine is something that is always evolving and never boring! “I appreciate the trust our clients’ place in me when choosing OVH for their pet’s care♥

Kristen is a Portland native who enjoys sampling Portland’s vast options of dining and micro-brews.
