April 1st, 2021 Update

To the entire pet loving community,

At the Emergency Veterinary Clinic of Tualatin, we are dedicated to remaining open and available for pet emergencies, and will continue to do so throughout this pandemic.

Despite the pandemic and even during severe weather, wildfires, and other challenges, we have never closed our doors. Due to our available cage space at times, we may reach maximum capacity: meaning, we temporarily cannot receive additional patients. Additionally, we are still requesting that any stable or non-urgent problems please seek an appointment with their general practitioner, rather than attempting to seek care in our emergency room. With the recent retirement of our amazing colleague, Dr. Andy Nuijens, we are temporarily operating with fewer veterinarians on staff than we would prefer. We are actively hiring in order to provide more service to our community.

The Emergency Veterinary Clinic of Tualatin is staffed with highly skilled emergency veterinarians. Our emergency doctors do perform common emergency surgeries: such as, c-sections, foreign body removal, pyometra and gastric dilatation and volvulus, splenectomy, laceration repairs, and other minor procedures. As we are not a specialty hospital we do not have surgical specialists on staff, and as a result, any advanced procedures are typically referred to an appropriate specialist. We do not perform scheduled surgeries, such as dentals, spay/neuter, or mass removals. We do not perform any orthopedic or fracture repair surgeries. We also do not perform vaccinations or sell flea prevention.

If you are waiting in our parking lot to be seen, you may notice patients coming in and out of the doors as you wait. Our building actually is the home for three separate companies, and they each have their own patients, staff and phone lines. Veterinary Diagnostic Imaging Centers operate Monday through Saturday, and Cardiology Northwest operates Monday through Thursday. If you are watching patients coming and going while you wait, please know that they may be unrelated to the emergency room.

Patients that arrive at our clinic will be triaged and placed in a queue for our doctors. We prioritize patients based upon our triage policy, and this means critically ill patients, or those with specific conditions, must be seen first. Unfortunately, this can result in significant delays for patients who still require care but are not as urgent. We ask that you wait for guidance from our staff after triaging your pet, if stable, we may offer for you to wait at home or somewhere more comfortable than your car. Our goal is to notify you of this option within 30 to 60 minutes of your arrival. Prior to leaving our facility, please wait for our staff to discuss your pet’s triage status. If your pet has urgent needs we may need you to remain on site.

We thank you for your ongoing understanding and kindness. We can guarantee our staff has been working tirelessly around the clock to provide care to our patients and clients. We are eager to be able to provide service to all patients who request it: as well as, reduce our wait times and return clients to the exam rooms, when it is safe to do so.
