Meet Our Veterinarians

Tanya ten Broeke, DVM

Tanya ten Broeke, DVM

Veterinarian Owner/Medical Director & Fear Free Certified Professional

Dr. ten Broeke (pronounced “TEN-brook-ee”) was raised in Austin, TX. She knew she wanted to be a veterinarian since the age of 9, and spent her youth memorizing animal facts from the Encyclopedia Brittanica, tending to injured butterflies, fireflies, and frogs, and advocating for ants’ rights.

Always a sensitive soul, she was diverted away from the veterinary field and found herself with a bachelor’s degree in Mechanical Engineering from the Colorado School of Mines. After a short career in environmental engineering, she returned to her true passion and earned her Doctorate of Veterinary Medicine in 2002 from the Atlantic Veterinary College in Prince Edward Island, Canada. Dr. ten Broeke worked in mixed, equine, and small animal hospitals before purchasing Gladstone Veterinary Clinic in January of 2007. She loves the relationships she develops with her clients and patients at GVC, and has a special place in her heart for her senior patients, and works hard to keep them comfortable.

Dr. ten Broeke has done veterinary volunteer work in developing countries since 1998, mainly in Guatemala, Nicaragua, and Peru. She also serves on the board of Sustainable Vets International, a non-profit organization with a focus on training local veterinarians in remote areas of developing countries. Dr. ten Broeke volunteers with Feral Cat Coalition and the Portland Animal Welfare (PAW) Team, has served as President and remains on the Executive Board of the Portland Veterinary Medical Association, and is very involved in a local women’s veterinary leadership group. In her precious spare time, she enjoys biking, snow-shoeing, kayaking, photography, traveling off the beaten path, hiking, and camping and spending time with her rescued critters. JuneBug is a ridiculously cute basset hound-shar pei mix, and an Ambassador for the hospital. Radar is an easy-going yellow lab who was released from the Canine Companions for Independence service dog training program because he could not pass Calculus. Pido is an orange cat who thinks he’s a dog, and Salty is a long-haired tortoise-shell cat who was abandoned outside the clinic in a winter storm. Salty’s demands include no less than 10 pets before she’ll settle down to eat her breakfast.

Cassi Snyder, DVM

Cassi Snyder, DVM

Associate Veterinarian & Fear Free Certified Professional

Dr. Snyder was born in California but grew up in Michigan. She spent her childhood dividing most of her time between caring for the many family pets (including cats, dogs, rodents, and reptiles) and dance class. She continued to teach and choreograph competitive pieces for her dance studio as she was getting her Bachelor’s degree in biology at Alma College but sadly had to “retire” when she moved for veterinary school. She received her veterinary degree from Michigan State University College of Veterinary Medicine in 2015.

Dr. Snyder’s love of good food and animosity towards winter led her and her boyfriend Jared to move to Portland as soon as she was done with veterinary school. She immediately started practicing at a clinic in Warren, where she stayed until joining Gladstone Veterinary Clinic in early 2017. Dr. Snyder loves working with such a kind and devoted team at GVC. Her special interests include feline health and well-being, geriatric care, and internal medicine.

In their spare time, she and Jared like finding beautiful hiking trips, great places to eat, and places to explore in the city of Portland. They also enjoy taking ballroom dancing lessons and love to salsa, Cha Cha, and waltz. They are owned by their two cats, Chandler and Hercules—littermates who share the family’s intense passion for food.

Kristi Winkler, DVM

Kristi Winkler, DVM

Associate Veterinarian & Fear Free Certified Professional

Dr. Winkler grew up in Northern California’s wine country. Her life-long passion of veterinary medicine began at the family farm and continued throughout her formative years in 4-H bottle raising rabbits and bottle-feeding an orphaned calf at her great-grandmother’s farm. At the young age of 5, she sneakily spent her naptime training her brand-new kitten “Lucky” to climb to the top bunk of the bunk bed, so she could sleep with her.

This passion continued in the animal biotechnology program at UC Davis, and during her master’s program in clinical microbiology. Dr. Winkler graduated from Western University of Health Sciences College of Veterinary Medicine in June of 2012. She decided to move to the beautiful Portland area after completing several externships in and around the Portland area during her last year of veterinary school.

Dr. Winkler has a special interest in public health, zoonotic diseases, reptile and small animal exotic medicine, and ophthalmology. At work, she is supervised by her crested gecko Salazar. Dr. Winkler shares her home with her three cats (Dacts—a polydactyl, Helix—named for the helix-like pattern on his back, and Yoda—well, that’s self-explanatory), and her Fences for Fido rescue black lab mix Fenrir, named for a dog-like creature in Norse mythology. She also is entertained by a 3-legged rescue sugar glider named Fury and a young ball python who has yet to be named. In her spare time, she loves to work on her older house, bake, kayak, road bike, garden, and go antiquing.
