Hospital Policy Update

If there are two no show appointments, with no phone call prior to cancel, within a six month period, there will be an associated cost of $25 added to the next visit.

We will then require a non-refundable deposit for the cost of the exam ($47.50) for any further appointments.

Thank you for your cooperation and understanding.
