Mission Statement

The Emergency and Critical Care Service working closely with your regular veterinarian will make available the highest level of care for patients and their owners. We will provide around-the-clock services every day, so that no matter when a situation arises, quality veterinary care is available. We welcome challenging, complicated cases and have an ongoing commitment to approach diagnostics and treatments aggressively. We will always provide and have access to specialized medical and surgical procedures as well as advanced in-house diagnostics. We will approach all patients with the knowledge that they are cherished family members. We are devoted to providing a caring environment that treats people and animals with dignity, kindness and respect.

We’re open when your family veterinarian’s office is closed... nights, weekends and holidays - 24/7

Few aspects of pet ownership are more terrifying than when an animal is taken ill in the middle of the night or during weekend hours when your veterinarian’s office is closed. Our Emergency Service exists to care for your pet under just these circumstances, and we’re no farther away than your phone, 24 hours a day. A medical diagnosis takes more than a phone call, but that’s where it usually starts as our well trained and caring staff member answers your questions and directs you on how best to cope with your pet’s problem. We treat a variety of medical and surgical conditions affecting dogs and cats. When you arrive, your pet will be examined and assessed by one of our critical care veterinarians who will explain the treatment options available to you. Please remember that cases are seen on the basis of need, with the most severely affected patients being seen first.

Critical Care Medicine Available 24 Hours a Day, Every Day,
365 Days a Year

Veterinary Emergency and Critical Care Medicine is a veterinary specialty that can save a pet’s life. Should your pet become injured, or suddenly develop an acute, life threatening disease, he or she will require prompt, emergency care. In addition to the initial emergency treatment, in some cases many days may be needed for the disease process to run its course before recovery occurs. During this time, close monitoring and advanced life support measures in the critical care unit (CCU) may be needed. Much of what happens in the critical care setting is initially planned for and started in the emergent phase of the disease. A vigilant team led by a veterinarian who is specially trained in emergency and critical care medicine will improve the quality of care your pet receives during this crucial time, resulting in a greater likelihood that he or she will survive. Critical care clinicians communicate daily with pet owners and involve the referring veterinarian in the ongoing management of their patients.

A fully equipped state-of-the-art veterinary hospital…

By referring you to us, your regular veterinarian is demonstrating his/her trust in our ability to properly care for your pet. We are fully equipped to handle virtually any circumstance that may arise. Our state-of-the-art equipment and treatment regimens are identical to those found in human hospitals. Our superb in-house laboratory can provide fast, accurate, lifesaving diagnoses enabling us to aggressively and effectively treat your pet. In order to be proactive rather than reactive, we have an extensive monitoring network and outstanding professional and support personnel. In those circumstances that demand it, the Emergency and Critical Care Service has ready access to the on-site Board Certified Specialists that comprise the Regional Veterinary Referral Center. When seconds count … we are here for you!

Compassion and dedication…

As you leave the hospital, you will be given a copy of your pet’s record including all X-rays and results of diagnostic tests. The attending doctor will contact your regular veterinarian upon discharge to notify them of your visit, and we remain available to them even after your pet’s stay with us is completed. We understand that it takes much more than just medical skill to fully care for animals. It takes compassion and dedication – something to remember as you consider the kind of care you want to give your pet. We care about that one special pet – yours!
