Who We Are

The veterinarians of Canada, like their colleagues around the world, desire the ability to manage all of their patients care from admission to discharge. Likewise, the patient’s owners prefer to have their animals stay at one facility and to be cared for by a veterinarian or veterinarians that they know and trust.
Having spent a considerable amount of time working with veterinarians in Canada, our team determined that a mobile ultrasound service would allow for seamless patient care with minimal to no patient transport, faster and less intrusive diagnostic testing and cost effective patient care for the pet owners.
We elected to offer not only abdominal, cardiac and small parts ultrasound but also provide interventional procedures necessary to fulfill the diagnostic pathway. By doing so, we are capable of scanning a patient, working with attending veterinarians to assess patients for biopsy or aspiration and then collecting any samples that may be required to accurately diagnose and address the underlying concern.
