Dr. Amy Tongue - Owner

In May of 2010, Dr. Amy Tongue purchased Oswego Veterinary Hospital and will continue the 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 in 1998 and spent the next three years at a practice in rural Northern California working on a large variety of large and small animals. 

After meeting her future husband, a Lake Oswego native, and joining him in Oregon in 2002, Amy began practicing in Lake Oswego. She joined Oswego Veterinary Hospital in late 2005. She and her husband, Tom, have two boys, two dogs (Piper and Abby) and a horse. Amy's medical interests lie in surgery and general medicine, though she enjoys the diversity that veterinary medicine has to offer. In her free time, she enjoys exploring the Oregon trails on horseback, reading, and hiking.

Kathy grew up with dogs and horses on a citrus farm in central Florida. She earned a B.S. in biology from Davidson College in North Carolina and her veterinary medical degree from the University of Florida. 

Upon graduation, Kathy lived in Japan for 6 months before moving to Gig Harbor, WA where she practiced on both family pets and farm animals for over 3 years. In 1992, Kathy moved to Portland with her soon to be husband, Mark, and started practicing here at Oswego Veterinary Hospital.
