To Help Us Serve You:

  • Please try to be on time for your appointments. We consider your time and ours very valuable and make every effort to keep our office running on time. Since we do not practice obstetrics, emergencies rarely take us away from regularly scheduled appointments.
  • If you are going to be more than 10 minutes late, please call to let us know.
  • If you cannot keep a scheduled appointment, let us know 24 hours in advance.
  • If you are a new patient and cannot keep your appointment, please let us know 48 hours in advance. We allot one hour for your first visit to our office and would appreciate knowing well in advance if you cannot make it.

Phone Calls

Telephones are open Monday through Friday, 9:00AM to 12:00PM and 2:00PM to 5:00PM. Messages are answered as soon as the doctor or nurse practitioner is available. The phone number is (310) 451-8144.
