WHY SOUND VETERINARY CARE
Quality mobile ultrasound
1
Expanding access to cardiology and abdominal ultrasounds
In response to the shortage of specialists in Hawaii, Dr. Graas provides high quality image acquisition and a direct link to board-certified specialist interpretation.
2
Specialist validated reports
All studies are submitted to board-certified specialists (Cardiac Vet, Heartline and Antech). Reports include detailed treatment and long term monitoring recommendations.
3
Proven diagnostic quality
Our standards are vetted by board certified specialists. Dr. Saelinger, DACVIM (cardiology), noted: "Dr. Graas is highly skilled in echocardiogram image acquisition… his images are superb and histories are detailed."
4
Statewide accessibility
Dr. Graas is committed to serving all of Hawaii, with monthly visits to Kauai, Maui, and the Big Island. If you are located on Lanai or Molokai, please contact us! Pet owners on Kauai should contact Paradise Animal Clinic or Kauai North Shore Animal Clinic to schedule with Dr. Graas.
5
No case too small — no minimums
Dr. Graas will visit your hospital, or your home, for even a single ultrasound. Sound Veterinary Care's priority is to improve access to quality imaging Hawaii-wide, without exception.
6
Urgent & on-call imaging
When time is of the essence, Dr. Graas can help. Same-day ultrasound appointments are available daily for veterinary hospitals. Contact Dr. Graas directly if there is no online availability.
“Dr. Graas and I have worked closely together for the past 5 years, as I am a veterinary cardiologist who interprets his echocardiograms along with other boarded cardiologists at Cardiac Vet. He is highly skilled in echocardiogram image acquisition and also preliminary interpretation (knows what constitutes an emergency). Dr. Graas consistently provides high-quality, diagnostic images and has extreme conscientiousness to patient care. All cardiologists on our team enjoy reading his studies because not only are his images superb, but he also takes the time to provide detailed histories, which creates a much better, comprehensive report. His level of care radiates through his imaging, the time he takes to provide the details regarding patient history and his responsive and kind nature.”
