Making an Appointment

Whether you have a physician referral or are self-referring for a second opinion, our scheduling team will be able to set you up with the right specialist for you. An initial consultation can be scheduled within 48-72 hours of your call.


We offer free valet parking, which is available at the main entrance of the hospital. You may also park for free at one of the visitor parking garages.

When you arrive, you and any care partner(s) will be asked to check in at the first floor main hospital desk directly inside the front doors. You will then be directed to the Department of Radiation Oncology on the ground floor, where the front desk can provide your complimentary parking or valet ticket.
