We use an automated appointment reminder system that will call you 48-hours prior to your appointment. Please listen carefully to the message and press "1" to confirm the appointment and "2" if you need to cancel for any reason. If you do not respond to the message a staff member will contact you to confirm appointment. If you are not at home, a message will be left on your answering system. Failure to notify us of a cancellation prior to 48-hours before your appointment may result in a charge of $20.00.

Helpful Hints:

  • If you participate with an HMO please make sure your primary doctor has authorized your visit. Patients will not be seen without prior authorization.
  • For first-time patients, please return via postal mail or bring a completed Patient Information form with you at the time of your appointment (photocopied insurance cards will need to be included for our records)
  • For prescription refill requests, any calls received after 12:00 may not be called in until the next business day.
