San Francisco Regional Mensa

Fresno City Hall


San Francisco Regional Mensa (SFRM) is a chapter of Mensa, the international society for people who score in the top 2% on IQ tests. The goals of the group are to provide and encourage social and intellectual interaction. There are approximately 2000 members in the San Francisco Bay Area and the San Joaquin Valley and we regularly schedule 80+ events each month. As of March 2012, SFRM is the fourth largest Mensa chapter in the US.

Mensa is for those who rejoice in the exercise of the mind. If you enjoy mental challenges and revel in the interplay of ideas, Mensa is an organization that will stretch your mind and expand your horizons.
