Every patient receives a comprehensive evaluation and has an individualized medical team dedicated to his or her care. Our patients and their parents or guardians become our partners in their own care.

Insurance Information

We welcome most insurance plans. We also offer a sliding-fee scale for patients who are uninsured. If you do not have medical insurance, we will help you find the coverage that is most appropriate for you.

Making It Easier for You

We want you to have a positive experience as a Montefiore Medical Group patient. We offer:

  • Easy accessibility by car, bus or subway
  • On-site parking
  • Convenient hours


As a partner with your healthcare team, there is a lot you can do to be active in your care. Here is a checklist to help you:

  • Be honest with everyone on your child’s care team about his or her medical history.
  • Bring a list of all your questions about your child’s health. Put the questions that are most important to you at the top.
  • Bring a list of all medicines, vitamins and herbal supplements your child takes to every appointment.
  • Tell your healthcare team about any other care providers your child sees so we can include them on your child’s healthcare team.
  • Learn about your child’s conditions, treatments and any medical tests your child will be getting so you can ask questions or address concerns you have with your child’s healthcare team.
  • You are the center of your child’s healthcare team. Work with the team to develop and follow a care plan that’s best for you and your child. Ask questions, be honest about what does and does not work in the plan, and make suggestions about what might work better.
  • Do your best to keep scheduled appointments, and call to reschedule or cancel as early as possible.
