Contact Us
Your call is extremely important to us. Our friendly knowledgeable staff is here to answer your medical questions and schedule or re-schedule appointments without delay. Overnight phone messages are checked first thing in the morning on the following business day.

Is it an emergency? Should I call?
You know your pet best. If you feel something is not quite right, please call. You can never be wrong for asking a question and it will ease your mind. During regular business hours, we are here to attend all emergencies. Call first to ensure our triage team is ready to receive you and your pet.

Can I email your office?
No. Because we provide medical services to your beloved pets, we are unable to monitor e-mails regarding patient care on a timely basis. In an emergency, when seconds count, email is not the preferred method of communication.
