His Practice Philosophy…

I strive to provide the highest quality of advanced surgical care by strictly adhering to accepted standards for the treatment of animals. As a result, I, along with local veterinary hospitals, am able to give pets the absolute best veterinary care.

As a member of your family, your pet deserves nothing less than the best care available. My commitment to having the most advanced technology is unrivaled. My priority, however, lies with giving you and your family all the support you need – through communication, care and compassion.

I am highly trained and experienced in providing prompt and intensive management of patients with life-threatening conditions and those requiring extraordinary supportive care.

My multi-disciplinary approach and close cooperation allows me to offer the best care available to the patients entrusted to me.

I am committed to using science, technology and compassion to provide exceptional care for pets and their families.

My caseload encompasses patients with a wide range of orthopedic, neurologic, oncologic (cancer), thoracic, and soft tissue problems. I am available for surgery, consultation, assistance with difficult surgical cases, or when the use of specialized surgical equipment or techniques is required. My combined effort allows me to confer on patient management, to be readily available for trauma or other emergency referrals, and to further expand our own surgical subspecialties. My practice is equipped with the latest specialized instrumentation and equipment. The safest anesthetic agents are used, and patients are continuously monitored throughout anesthesia. Experienced, registered veterinary technicians and a well-trained technical support staff play a key role in perioperative intensive care.

Your pet deserves exceptional care.
