We are the only national social fraternity that requires specific fields of study and Triangle is one of only three national fraternities that does not have a Greek letter name.
The Iowa State Chapter was founded in 1964 and has a strong tradition of recruiting academically focused men. In addition, we strive to find men that live their life with integrity - those who make the choices to be leaders, scholars, professionals and gentlemen in all aspects of our lives.
