Flexible Office Hours

We have attempted to provide flexible hours to accommodate patient needs and to minimize wait times.  Because of our commitment to patients in the hospital, individual physician hours vary.  There is someone in the office to answer telephone calls from 8:30 am until 5:00 pm, Monday through Friday except holidays.

Appointments may be made only during these hours; every attempt will be made to provide you with an appointment in a timely manner.  Because of the nature of our practice, emergencies do arise and the office schedule may be "running behind" or your doctor ma not be available  Every attempt is made to minimize the occurrences; if emergencies arises you may be asked to reschedule your appointment.  If you find that you are unable to keep your appointment please notify us at least 24 hours in advance if possible.
