INN | Institute of Neurology and Neurosurgery in Passo Fundo, Brazil

The Institute

Pioneering work that became a national reference.

Founded by Dr. Paulo Sérgio Crusius, the INN was born as the first neurology and neurosurgery service in Passo Fundo and home to the first medical residency in the specialty in inland Rio Grande do Sul, officially recognized by the Brazilian Society of Neurosurgery.

Today we operate with a reference-level structure at Hospital São Vicente de Paulo and are part of the innovation ecosystem of Instituto Aliança Empresarial, uniting more than five decades of experience with continuous innovation in processes, technology and leading-edge therapies.
