Call 203.869.1145 to make an appointment or request an appointment online.  You will be asked for your insurance card information when you call.

Note: We require 24 hours notice to cancel an appointment.

Please bring to your appointment:

  • Current insurance card
  • List of current medications and medical conditions
  • Primary-care physician address and phone number and contact information for other physicians involved with your care

Patients who are new to ONS or who have not visited our offices in more than a year should complete the patient registration form on the ONS Patient Portal. If you do not pre-register on the patient portal, you will need to arrive 20 minutes before your appointment time to complete paperwork. This will expedite your check-in.
