Dear Valued Patient,

We hope that you and your family have been safe and healthy during this time.  We are extremely grateful for your patience and support during this pandemic. We remain committed to being partners in your health and providing you the best possible care.  We wanted to give you an update on how we are continuing to meet your needs during this time. Your safety is our top priority!

We currently have availability for both in-person and virtual (video) appointments.  We understand that it has been a long time to put health matters on hold.  If you do not feel comfortable to come to the office, we are happy to help manage chronic medical conditions through virtual visits now!  Virtual visits are billed to your insurance just like an in-office visit; check with your insurance plan about coverage. To schedule either kind of appointment, please call us at 312-922-3815 or send us a message through MyChart.  

FOR EVERYONE'S SAFETY, WE ARE STILL UNABLE TO TAKE WALK-IN OFFICE OR LAB APPOINTMENTS. We can only see people with appointments that are scheduled ahead of time.  Please contact your doctor if you feel that you need an in-person visit.

We also have a new system for laboratory services and allergy shots. AGAIN, WE ARE UNABLE TO TAKE WALK-IN APPOINTMENTS to safeguard your health and the health of our staff. If your doctor has decided for you to come in for lab tests or some other laboratory service (like a vaccine or injection), we will schedule you a specific time to come to the lab.  For allergy shots, please continue to message the office at least 24 hours in advance, but now we will also schedule you a specific time to come in as well.

For all appointments (visits with a doctor or a lab visit), we would appreciate you being on-time and arriving as close to your scheduled time as possible.  We are scheduling set times to minimize wait times and crowding to keep you as safe as possible.  You are required to wear a mask that covers both your nose and mouth: please wear one when you leave your home, keep it on the entire time when you're here in the office, and only remove it after you return home.  When you arrive, we appreciate your patience so please continue to physically distance yourself when you arrive.  

There are a few additional policies because again, our top priority is your safety!  

First, when scheduling an appointment and again when you arrive, you will be asked screening questions to see if you have any symptoms of COVID-19, traveled in the past few weeks, or had close contact with someone who has had COVID-19.  Please do not come to the office if you have any symptoms of COVID-19 or any flu-like or cold symptoms.  This is to protect our staff and other patients who are visiting the office.  Call the office so we can change your appointment to a virtual visit, or we can reschedule your appointment.

Second, only patients with a scheduled appointment time will be allowed to enter the office.  We request that any companions who come with you wait outside the building for you.  Please contact your doctor before your appointment if you need special accommodation. We appreciate you being on time so that we can bring you back promptly to an exam room upon your arrival.

Third, doctors and staff will be wearing masks in the office.  Doctors will also be wearing other protective equipment during your visit.  While maintaining a clean office has always been our practice, we have added extra precautions based on CDC recommendations to ensure our office is sanitized frequently before and after your visit.

Thank you for your understanding and patience.
