Led by Dr. Andrea Oas, DVM — Washington State University College of Veterinary Medicine, AVMA member. Board-certified surgical care now available.
North Davies Veterinary Hospital provides individualized, same-day veterinary care for pet owners around Lake Cassidy — just 15 minutes away via SR-9.
Lake Cassidy sits between Marysville and Lake Stevens, and most pet owners around the lake are already within easy reach of North Davies Veterinary Hospital via SR-9 — about 15 minutes, no highway changes. It’s a quieter, semi-rural stretch of Snohomish County, and a lot of our Lake Cassidy patients tell us they want a vet with the same unhurried, small-town feel as home.
As an independently owned, full-service practice, Dr. Oas and her team build every treatment plan around your pet, not a corporate checklist. Since August 2026, our team also includes a board-certified surgeon, bringing advanced surgical expertise close to Lake Cassidy.
When your pet needs to be seen quickly, we do everything we can to fit them in the same day, based on availability.
Most Lake Cassidy patients find the drive to North Davies Veterinary Hospital via SR-9 South quick and direct — about 15 minutes with no highway changes.
Address: 9309 N Davies Rd, Lake Stevens, WA 98258. Hours: Mon 8:00 AM–5:00 PM, Tue–Thu 7:00 AM–6:00 PM. Please call to confirm Friday availability, which is expanding.
If your pet needs to be seen, reach out to us as soon as possible during our open hours. Let our team know what is going on so we can find the earliest available time. Same-day appointments are based on availability, so the sooner you call from the Lake Cassidy area, the better the chances we can get your pet in quickly.
When you arrive, Dr. Oas or one of our veterinarians will take a thorough look at your pet to understand what is happening. We can often run diagnostic imaging or lab work in-house the same day, so we are not leaving you with more questions than answers.
Once we have assessed your pet, we will sit down with you and walk through what we found and what we recommend. Whether that means same-day treatment, medication from our in-house pharmacy, or a follow-up plan, you will leave with a clear understanding of what to do next.
North Davies Veterinary Hospital offers a full range of veterinary services for Lake Cassidy pet owners, from routine wellness care to advanced surgery.

Wellness exams and preventive plans built around your pet’s stage of life.
Core and lifestyle vaccines tailored to your pet’s individual risk factors.
Guiding new Lake Cassidy pet parents through every milestone of the first year.

At North Davies Veterinary Hospital, care is not just something we check off a list. Because we are independently owned, Dr. Oas has the freedom to make recommendations based on your individual animal, not a corporate protocol that applies the same approach to every patient.
Since August 2026, our team also includes a board-certified surgeon, bringing advanced surgical expertise within easy reach of Lake Cassidy. We are currently welcoming new patients from the Lake Cassidy area. If you are looking for a practice that will take the time to actually get to know your animal, we would love to meet you.
