We attempt to accommodate the scheduling needs of each patient at the most convenient time possible. Appointment timing is dependent on the day and length of treatment, if applicable. Evening hours are available in both our Naperville and Darien offices.



If for any reason you are unable to keep your scheduled appointment, please call our office and cancel or reschedule the appointment with a minimum of 24 hour notice. We reserve the right to charge for any missed appointment and this fee will depend on the type of visit.

Appointments can also be requested using our patient portal, accessible on our website homepage.  The portal should not be utilized for urgent matters and first-time consultations.

We ask that you make your next appointment every time you visit. This includes your appointments for labs, treatment and doctor visits.

Need a Ride?

The American Cancer Society Road to Recovery program provides transportation to and from treatment for people who have cancer who do not have a ride or are unable to drive themselves. Volunteer drivers donate their time and the use of their cars so that patients can receive the medical care and treatments they need.

Call 800.227.2345 to find out if Road to Recovery is available in your community or visit

Appointment Questions

I received a call from the “Doctor’s Office” leaving Hematology Oncology’s telephone number. Why do you not identify your office by name?

  • Health Insurance Portability and Accountability Act, HIPAA, as outlined by the Federal Government, is designed to protect your privacy. Unless your voice mail message includes your name, we are unable to identify our practice or leave a detailed message.

May I bring family members to my appointment or treatment?

  • We highly recommend family members or a close friend join patients during their doctor visit(s) or treatment(s).

How do I prepare for my first appointment?

Why is there a longer wait to see the doctor or for my labs on some days?

  • HOC provides individualized care to best serve the needs of our patients. There are times when the staff must handle an emergency, connect with other medical professionals or respond to unexpected needs. Unforeseen issues may delay treatment times.  While we understand that no one likes to be kept waiting, it is important for the staff to take care of urgent issues as they occur as a matter of safe medical practice.

Why does the doctor order follow-up appointments if there is no change in my condition and my test results are clear?

  • Good medical practice generally includes follow up and surveillance.   By making a follow-up appointment, the doctor is given an opportunity to revisit past concerns and assure you that your health status is stable.  There are circumstances, however, when the doctor feels no follow up is required and will direct you back to your primary physician.

I returned a call/message left on my phone but the line just kept ringing.

  • Returning a call using a number from your caller ID may be a line that is meant to be an outbound line only.  Always use the primary numbers associated with either office to be sure the call is forwarded to the staff or answering service.
