Dr.  Onyemaechi Okolo-Taku joined Ironwood Cancer & Research Centers in 2021. She has been blessed with a multicultural and multinational upbringing, which has greatly influenced her everyday interactions, her cultural competency, and her work. She was born in Nigeria, and lived there with her family until the age of 8, after which she moved to Texas. Subsequently she spent 3 years in an international boarding school in England. Dr. Okolo- Taku completed her undergraduate degree at The Johns Hopkins University in Baltimore, Maryland, and after college moved to Spain for a little over 1 year.  She spent the first two years of medical school at St. George’s University School of Medicine in Grenada and finished off in New York City. While in medical school she did international electives in Nicaragua and the Czech Republic. After NYC, she moved to Tucson Arizona, where she completed her internal medicine residency,  hematology and oncology fellowship, and  integrative medicine fellowship. She loves traveling, meeting new people, and learning about new cultures.

Dr. Okolo- Taku has always been interested in oncology and hematology; the fast moving developments in the field is changing the way we treat people and finds it is so inspiring to be able to guide patients in this field. She loves the interactions that she has with her patients and forming good relationships with them. Additionally, she has an interest in evidence based integrative oncology, and has completed a fellowship from the Andrew Weil Center for Integrative Medicine. Her interest in integrative oncology perfectly complements her love for hematology and oncology as it allows her to treat a variety of patients while also providing the opportunity for her to counsel, educate, and conduct research and interventions with evidence based complementary practices.  She has many publications in hematology, oncology, and integrative oncology ranging from case reports to literature reviews, as well as retrospective research.

Another big interest of hers is community engagement and health disparities. She believes that the accessibility of healthcare to all, regardless of race, gender, religion, or culture leads to better medicine. Community engagement leads to more trust in physicians as well as willingness on the side of the patient, to be more proactive in their health.

Her non-work interests include spending time with her husband and their two dogs, travel, cooking and dining at new restaurants, hiking, gardening, and art.
