Dear Valued Client,
I am writing to share an important update regarding the future of Animal Surgery and Vaccinating Clinic.
After thoughtful consideration, I have decided to transition leadership of the practice. It has been one of my greatest honors to care for your pets and to be trusted with their health over the years. I am deeply grateful for your loyalty and support.
I am pleased to introduce Dr. Oas, who will be assuming responsibility for leading the clinic moving forward. Dr. Oas is a skilled and compassionate veterinarian whose values, medical judgment, and commitment to patient care align closely with the standards that have guided this practice. I am confident that you and your pets will continue to receive exceptional care.
Born and raised in the Marysville area, Dr. Andrea Oas is excited to be back practicing locally in the community. From a young age, she has had a passion for veterinary medicine which eventually led her to Washington State University to acquire her doctorate in the field. Andrea is a big animal lover, which is confirmed with her (6) Frenchies (Nizmo, Lilah, Jazzie, Tw***ie, Diddy, and Mocha) and (2) Pigmy Goats (Ellie and Evee). When not at home with her animals, you can usually find her in the surgery or dental suite, which is like her second home. She is looking forward to meeting and continuing to provide excellent care for your furry loved ones.
I encourage you to continue entrusting your pets’ healthcare to Dr. Oas and the dedicated team at Animal Surgery and Vaccinating Clinic. I believe the practice will remain a trusted and comforting place for you and your pets for many years to come.
Thank you again for the privilege of caring for your beloved animals. I wish you and your pets continued health and happiness.
Warm regards,
Dr. Kongchatree
