The Doctor’s Doctor

As an Internist, Dr. Okolo cares for her patients for life. She sees them in her office and manages their care even when other doctors are involved. They may ask for her help with their own patients. Dr. Okolo can act as a consultant to other physicians to help solve puzzling diagnostic problems, and help facilitate complex patient treatment processes.


This is why a Doctor of Internal Medicine is often called, “The Doctor’s Doctor.” Dr. Okolo welcomes physician collaboration and consulting engagements.
