Columbia West Side Pediatrics

An office of ColumbiaDoctors Faculty Practice Pediatrics




We Are Open!

The doctors and staff at Columbia Westside Pediatrics are here for you.

In an effort to keep us safe while continuing to provide exceptional medical care, our policies and patient flow in the office have changed, and will continue to change to meet COVID-related challenges. Please visit this site frequently for the latest updates.

We will be strictly adhering to our long-standing policy of not seeing patients on a walk-in basis. All patients must have an appointment to be seen in our office. After assessing the visit type we will make a judgement as to whether telehealth or an in-person visit is preferred. We ask that if you have forms, medical record requests, medication refill requests or other housekeeping issues, that you please make every attempt to reach us by phone or electronically.  See below for information about how to sign up for secure electronic communication with our office.
Morning appointments are reserved for our youngest healthy patients (under 2 years old) for well care and vaccinations. The afternoon is for older patients needing vaccines. All other patients will be seen on a case-by-case basis in the late afternoon and early evening Monday through Thursday, and only after speaking directly with a physician to determine the need for an in-person visit.

Anyone entering the office must wear a mask over their mouth and nose for the entire time they are in the office. Only one adult is allowed in with each child. That adult must be healthy and fever-free. We will take temperatures of all people entering the office and you will be denied access if you are found to have a fever.

Please arrive on time for your appointment. If you are early, please do not attempt to enter the office. In order to guarantee that you and your child are not exposed to others, we are enforcing a 5 minute grace period for late arrival. If you are more than 5 minutes late, please call the office so that your child can be rescheduled.

Thank you for your patience and understanding during this time. Please stay safe and healthy. We miss you all and hope we can see you soon, safely.

As of July 2020, there are not enough supplies in the medical center - neither in our offices nor at the main hospital - to perform screening tests for asymptomatic children who need 'clearance' for things like planned travel, schools and camps.  Our limited supplies are restricted to sick children whose symptoms merit testing, and a clinician assessment is required before scheduling.  We apologize for the inconvenience and ask for your patience, as we cannot make exceptions to this policy.  We need to preserve our existing supplies for sick patients.
There are ways to get tests if you are not currently sick.  New York City and New York State are increasing local testing options, often free of charge.  For more information:
call 311 or 1-844-NYC-4NYC
new free testing spot is at 160 West 100th Street (NYC Dept. of Health building across the street from the 24th precinct)
Thank you for your understanding.  We remain deeply committed to your children and their health and well-being.
