Osa was born in Nigeria and lived there for 5 years before coming to the United States. Upon arriving in the U.S., Osa and his family shared small apartments with family friends in New York until his parents were able to afford renting their own apartment. His family eventually settled in Union, NJ, where Osa lived for a majority of his life with his parents and two siblings.
Osa attended Rutgers University, New Jersey’s state university from which he graduated Magna Cum Laude with a double major in Biological Sciences and Psychology. While matriculating at Rutgers, he participated in stem cell research and was president of Phi Delta Epsilon, the medical fraternity, which he used as a conduit to volunteer at numerous hospitals in the surrounding area. He moved to New York after graduation in 2012 to pursue his medical degree at NYU School of Medicine.
Since arriving at NYU, Osa has been very active in the community; he is currently the co-president of BALSA (Black and Latino Student Association) and he has been involved with Mini-meds and BASIS, two of the tutoring/mentoring programs offered by the school. He is also a school ambassador involved in helping plan events for incoming students.
