Winthrop Veterinary Services was founded in 1990 by Dr. Betsy Devin-Smith. The practice started out small and has grown and changed to meet the needs of the Methow Valley. Dr. Gina Pastore moved to the Methow Valley from Vermont and joined the practice in 2009, recently making the transition to ownership in 2019. The name has changed slightly to Winthrop Veterinary Clinic, but the high quality animal care remains the same.

"Dr. Gina"

was born and raised in Vermont.

She graduated with a degree in Zoology from Connecticut College. After graduation she packed up a car with her best friend and ventured out west. Living in Seattle, WA she found her love of veterinary medicine working as a Veterinary Technician and decided to pursue her veterinary degree. She graduated from the Royal Veterinary College at the University of London, England in 2005 and worked in Vermont for a few years before moving out west again. Dr. Gina has been with Winthrop Veterinary Clinic since 2009 and purchased the clinic from Dr. Betsy in 2019. She is proud to serve the wonderful community of the Methow Valley and care for all of the four legged family members. She and her husband, Michael

(a fish biologist), enjoy outdoor recreation in all seasons with their two young children.

Since she was a teenager, Rachael

has always wanted to work with animals.

She moved to the Methow in 2015 from Spokane

after meeting her fiancee Kyle on an adventure cruise ship in Alaska. Rachael’s first job in the valley was with Sunny Pine Farms where she worked as both Caretaker to the goats and Cheesemaker. Her desire to focus on the medical aspects of animal care led her to join our veterinary clinic in the spring of 2018. Whether working as Care Coordinator or Veterinary Assistant, Rachael’s passion for animal care and varied skill set are always being put to good use. Rachael holds a Bachelor’s degree in Business from Eastern Washington University and is currently enrolled in the Veterinary Technician program through Penn Foster. She spends her free time in the mountains hiking and skiing with Kyle, and visiting her family in Spokane.

Jessie is proud to have

been raised in the Methow Valley.

She grew up on a horse ranch in Mazama, WA and after graduating from Liberty Bell in 1990 she went on to earn a B.S. in Zoology and Animal Science from Washington State University. As one of the first employees of Winthrop Veterinary Services over 20 years ago, her duties included hauling Dr. Betsy's young son Casey around in a backpack to accompany his mom on farm calls. Jessie enjoys the challenges and variety involved with keeping animals healthy.

She currently lives on the West Chewuch with her husband Stuart and her other animal friends; 2 dogs, 1 cat and a few chickens. Any spare time is spent outside in the garden or curled up with her cat and a good book.

Tammy Sutton and her husband Marvin

moved to the Methow Valley in 2010. She was born and raised in the midwest so having an opportunity to move to the Valley has been a beautiful adventure. Tammy joined our veterinary clinic in July of 2013, after experiencing the level of care she and her dogs had received from both Dr. Gina & Dr. Betsy. She has 4 dogs, Gracie, Sunny, Jed, Hope, 3 ducks and more chickens than she can count. In addition to her work she has Sutton Family Farm which provides farm fresh eggs to local restaurants and businesses.

She loves photography and being outside. Tammy has always been a self-described animal lover, and is grateful to be part of an animal clinic that provides compassion and care to pets on a daily basis.

Torre has been fortunate to work

with animals for a good deal of her life. 

With a PhD in Marine Biology, her eclectic jobs

have taken her to Antarctica, Greenland, and out to sea. 

Her favorite job (so far) was researching the diving

physiology of the marvelous emperor penguin. 

She spent six field seasons working near McMurdo Station, Antarctica, in a camp affectionately known as “Penguin Ranch”. She also met her husband in Antarctica, who lived in a place called the Methow Valley, and Torre has happily lived here since 2001. More recently, she has inspired other travelers about the wonders (and fragility) of Antarctica as a Naturalist aboard cruise ships. In the summers, she helps monitor Methow songbirds. After receiving exceptional care for her cats for many years at

Winthrop Veterinary Clinic, she is excited to now be part of the team, helping care for other clients’ pets. She is passionate

about birds and loves mountain biking, skiing,

and traveling with her husband. 

In the winter, she is a ski trails groomer for

Methow Trails, enjoying the wildlife of the

night from the cab of

a snow-cat.

"Dr. Sherrie"

was born in Portland and raised on the

Washington coast in Aberdeen. She attended

Central Washington University as a chemistry major

and completed her combined Bachelor of Science and DVM degree at Washington State University, graduating in 1993. Client education is a key focus for Dr. Sherrie, and helping owners appreciate the benefits of diagnostics to aid in understanding their pets' health concerns and guide decisions regarding treatment options is an essential role as a veterinarian. She integrated Chinese medicine into her practice after becoming certified in veterinary acupuncture in 2011.

When she is not in the clinic, she enjoys travel, hiking with her husband Mike, racing in triathlons, playing in a Marimba band and hanging out  with her two kitties. She also supports the Isla Holbox Spay and Neuter project, volunteering annually with their free clinics in Quintana Roo, Mexico. After nearly two decades of visiting

and vacationing in the Methow,

Dr. Sherrie is thrilled to

be able to call it her home.

I am so thankful that Winthrop Veterinary Clinic cares for my dog! Dr. Sherrie, Dr. Gina, Tammy, and the rest of the team are incredibly kind, competent, and knowledgeable. It is apparent that they truly care about the animals they care for and the work they do. The entire staff is professional, friendly, and very skilled in veterinary medicine. And their prices are fair and reasonable. We are lucky to have this clinic in the valley!

Kate grew up in Shoreline, Washington with a

love for the countryside, raising chickens in her backyard and riding horses at a nearby stable. Kate was introduced to the Methow Valley at six years old on a trip with her family and then again when she started working at Sun Mountain Lodge at the horse stables in the summer of 2016. After graduating from Washington State University with a Bachelors in Animal Science in 2018 she moved full time to live here. After six years at the horse stable and needing something new in her life with an interest in medicine, Kate found herself as a Care Coordinator here at the clinic. She enjoys spending time with her two Australian Shepherds, riding her horses in the mountains and fishing with her husband Trevor. Her family makes the drive over the mountains multiple times a year to marvel at her country life.
