Dr. Gretchen Stroh

Dr. Gretchen Stroh

I am a Class of 2016 graduate of the WSU College of Veterinary Medicine. My top interests in school were emergency, internal medicine, and surgery of companion animals. I obtained my Bachelor of Science degree from WSU in Animal Sciences in 2012 and went straight into vet school. I have known since I was a kid that I wanted to be a veterinarian and have worked hard to make that dream a reality. I grew up with a variety of animals, showing horses, dogs, and poultry in 4-H. My furry family includes a 2 year old orange tabby cat named Simon and a brand new 9 week old tuxedo kitten named Leo.

In my spare time, I enjoy spending time outdoors enjoying the beautiful Pacific Northwest, hanging out with friends and family, and curling up with a good book and my two kitties. I am so excited to join the awesome team here and can't wait to meet you and your furry friend!

In her leisure time, Dr. Schmidtke trail rides, often in the National Forests and National Parks of Washington state, and spends time with her husband, dogs, and horses at their small ranch in the Methow Valley.
