Overview
Mission
Education
What it reported doing in 2025
Annual meeting is comprised of interactive sessions encouraging an unstructured critique of speakers, participants and content. The meeting is geared towards practicing neurosurgeons, fellows, residents, and advanced practice providers (physician's assistants and advanced nurse practitioners).
Operating model
- Revenue model
- Earned-program. 100% of the money available for current operations came from fees and other program revenue.
- Distribution model
- Direct operator. The filing allocates 100% of reported program-service expenses outside its grant, affiliate-payment, and member-benefit lines. This expense classification does not rule out separately announced grant awards.
The verdict
STRONG - A large share of available resources goes toward mission work and the filed numbers largely add up. Total assets are small relative to annual expenses; liquid coverage is unknown and reported officer compensation is a large share of total spending, which may reflect staffing concentration.
