Center: Weston Center/Stevens Point
Years at Marshfield Clinic: 10

Dr. Adedayo Onitilo is a busy man these days. Not only does this oncologist/hematologist see a full panel of patients in Weston and Stevens Point, he is also the service line director for all of the oncology/hematology locations in the Marshfield Clinic system.

Add to that the philanthropic support he provides in terms of charitable gifts and volunteering at events, and the research he performs with Marshfield Clinic Research Institute​. He also chairs the Wisconsin Cancer Council and is on the board of the American Cancer Society's Wisconsin chapter.

"I think sleep is sometimes overrated," he said with a chuckle. "I'm trying to learn how to relax, but if I sit for five or 10 minutes, I'm usually looking for something to do. I believe working actually relaxes me"

Dr. Onitilo thinks that at least some of this comes from his rigorous education in his native country of Nigeria. Few people in the United States are probably aware that Nigeria is one of the most educated countries in Africa.

"As a child, your job is to do well in school. All of your efforts are around that," he noted. "I think you need to work hard at creating opportunities to polish your natural gifts."

Dr. Onitilo considers his leadership roles as honors bestowed on him by his colleagues, not as privileges. He still works as hard as ever on behalf of his patients. His thirst for knowledge has prompted him to earn his medical degree, complete a residency in New York and an oncology/hematology fellowship in South Carolina, where he also earned his master's degree in clinical research. Recently, he completed his Ph.D. in Epidemiology from Australia.

Outside of work, Dr. Onitilo keeps active through golfing, walking and other sports. He also enjoys traveling to new places and spending quality time with his family.
