"To help people in the Miami-Dade community have access to clear diagnosis in order to improve quality of life."
As a Miami-native, Dr. Costero Diaz created 305 Brains specifically to serve her community. We accept Medicare, Medicaid, and offer affordable payment plans because we believe access to neuropsychological care should never be limited by income.
From children as young as 3 to geriatric patients, our evaluations span the full human lifespan. Whether it's a 6-year-old with learning differences or a 75-year-old showing early signs of dementia, every patient receives the same depth of expertise.
A diagnosis from 305 Brains isn't the end of a process — it's the beginning of a customized plan. Every evaluation concludes with clear, actionable recommendations that improve daily functioning, open doors to services, and create a roadmap for healing.
We offer services in English and Spanish — because understanding your diagnosis in your own language is not a luxury. It's essential to the trust and quality of care every patient deserves.
Every assessment administered at 305 Brains follows validated, peer-reviewed protocols. We don't cut corners. Families come to us for answers — and we're committed to getting it right.
Built for the populations most underserved by traditional neuropsychological practices.

We support caregivers, parents, and teachers — not just the patient — through the entire process.
"We believe an accurate diagnosis — delivered with care — is one of the most powerful gifts a person can receive."
Too many people in South Florida are struggling without answers. Children labeled as "difficult." Adults told to just push through. Seniors dismissed as simply "getting old." The truth, in many cases, is that their brains work differently — and no one has taken the time to understand how.
At 305 Brains, we take that time. We believe in comprehensive evaluations, clear communication, and walking alongside families through the process — not just handing over a report and sending them home.
This is why we exist.
