Dr. Colin Bonnett

Dr. Bonnett was born and raised in Anchorage, Alaska, before going to college at Montana State University in Bozeman, Montana. Fortunately, the mountains and rivers of Montana and the Alaskan summers provided relief and distraction from pursuing a career with his undergraduate degree in Fish and Wildlife Management. He returned to MSU-Bozeman to complete a Master of Science in the microbiology department, studying immunology and infectious disease before enrolling in the Veterinary Medicine program at Washington State University in 2005. In addition to enjoying the diverse caseload and client interaction of general practice, his professional interests include minimally invasive surgical procedures (endoscopy/laparoscopy) and dentistry.

Dr. Bonnett is excited to be the newest member of the veterinary staff at Cascade Vet. When not working, he and his wife Kate and two kids (Ada 5, Evan 2) will be found along the rivers, trails, mountains, ice-cream stands and music festivals of the surrounding area!


Dr. Katie Harrington

Dr. Harrington was raised in Olympia, Washington. She attended Pacific Lutheran University and obtained a B.S. in biology and chemistry before earning her Masters in Business at Washington State University. Katie worked for 6 years as a software development manager before deciding to pursue her dream of becoming a veterinarian.

She then moved to Prague, Czech Republic for two years to work with Hill's Pet Nutrition in their Central European office building implementing software with veterinarians throughout Europe, Russia and Africa.

Katie is very happy to be back in the United States, on the sunny side of Washington to fulfill her dream of practicing veterinary medicine in a small town with her close friends and near her family. When Katie is not working at CVC you will likely find her running, hiking or biking...with Chris and her dog Emmie, Justin and Zacks's baby and dogs, or Colin and Kate's kids and Henny!
