Celebrating 10 Years of Advancement
For the past decade, the Peter O’Donnell Jr. Brain Institute has redefined what’s possible in brain science and care. By establishing a collaborative ecosystem where researchers and physicians work side-by-side, OBI delivers the latest treatments today while driving breakthroughs and innovation for tomorrow. The journey is far from over, but our commitment to our patients remains strong as we strive closer to our vision of a future without brain disease.

Message from the Center Director
“The O’Donnell Brain Institute was envisioned as a place where we could forge new frontiers and offer our patients therapies that just a few years ago might have seemed out of reach. United by our shared mission to overcome brain disease, every scientist, clinician, staff member, and administrator plays an essential role in bringing that vision closer to reality.”
