Our chapter, Beta Delta was officially chartered May 22,1948 when our school was still called the College of Puget Sound. Since that time our chapter has evolved with the times but always focused on the bond formed by our members' love of music. Membership ranges from Psychology majors to Music Performance majors and our members come from all areas of music: band, orchestra, vocal and piano.

Other chapters in the Nu Province include the Sigma Zeta chapter at the University of Idaho in Moscow, Idaho, and the Seattle, Tacoma, Spokane, and Moscow-Pullman Alumnae chapters.

For more history of the Beta Delta chapter view a timeline from the 1955-1956 yearbook, or read a summary of Sigma Alpha Iota activities in the Tacoma area from 1947-1957, written by Jeannette Jensen Chapman and presented to the chapter by the Tacoma Alumnae in 1989.
