Dr. Tongue grew up in the San Francisco Bay Area and has dreamed of becoming a veterinarian for as long as she can remember. After earning her Doctor of Veterinary Medicine from UC Davis in 1998, she began her career working with horses, cattle, and small animals in a rural Northern California community.

After meeting her Oregon native husband, she relocated to Portland and, in 2010, became the proud owner of Oswego Veterinary Hospital—their “third child” alongside their two sons, who are now off at college.

Outside the clinic, Dr. Tongue enjoys trail riding and horse camping, and devotes much of her free time to caring for Jasper, her energetic and affectionately demanding rescued German Shorthaired Pointer.

Dr. Trish’s career quite possibly began when at age 4, she asked her mom if she could go to college to become a bird. A few decades later, she graduated from the University of Minnesota College of Veterinary Medicine. Her adventures as a veterinarian started in rural southern Oregon making small town memories. Large animals, companion animals and wildlife served as teachers and guides. She cherishes those incredible adventures, life altering experiences, and foundational lessons.

Trish’s recent veterinary practice is focused on companion animals. As a practitioner her goal is to offer all the options available to help your pet live their best life and have their highest health. She is currently licensed to practice veterinary medicine in Oregon and Washington.

She cherishes each puppy visit as much as she honors each end-of-life transition. She celebrates and respects the bond we form with our four-legged family members. Trish believes that we share our lives with our animal family for a variety of reasons: to support each other’s evolution, to be each other’s teacher, to guide each other, and to learn to love without condition.

Trish is an Adult Chair life coach, a Nia white belt, an Awakening Women group temple facilitator, a Vipassana meditator, a volunteer for Not One More Vet, and a Hoffman Process graduate. She lives with her husband Lee, a windsprite named Birdy, and five fabulous cats; Fred – The Big Handsome, Shenandoah and Sonoma – The Valley Girls, Brother – The Romantic, and Hickory – The Irreverent.

As a groomer for Oswego Veterinary Hospital for over 15 years, Kristen not only cares for and loves your cats and dogs when they come to visit for a spa day but also has a few critters of her own.  Her blue-tongued skink named Binky is nearing 20 years old, she recently rescued a bearded dragon named Janet and also has adopted a Cavalier King Charles Spaniel named Bean who will be two in December. 

Her love of animals can be traced back to her early days on her aunt’s farm in Tillamook where she could be found in the fields mooing with the cows.  In her time away from the clinic she enjoys a few weekends a year camping in the PNW, traveling to Costa Rica as that is where she plans to retire and down to LA to see her nephew who is playing basketball at a local college and conveniently lives close to Disneyland. 

Kristen is very proud to take care of your four-legged family members and also truly enjoys the relationships she has built with each of her clients over the years.
