Yes...Tri Sigma does indeed have alumnae initiation! Is there a sigma alumnae chapter in the town where you're living now? If you're not sure, you can check out the website
www.sigmasigmasigma.org to see where the nearest chapter is. Start by contacting them...each alumnae chapter has guideliness on alumnae initation. If you have any more questions, PLEASE feel from to PM me!
