Nov 24 (Reuters) - Cassandra Seier, New York Stock

Exchange's head of international capital markets, died

over the weekend, a company spokesperson said on Monday, without

disclosing the cause of death.

"We are devastated by the news that our colleague Cassanda

Seier passed away over the weekend," an NYSE spokesperson told

Reuters in an email statement.

Before joining NYSE in 2022, Seier worked for more than 23

years at Goldman Sachs ( GS ), where she started her career as

an operations specialist in 1996, according to her LinkedIn

profile.

At NYSE, Seier was responsible for attracting new foreign

issuers from outside the U.S., placing her in a revenue-critical

role as the bourse continues to compete in an increasingly

crowded market.

She was one of the most prominent women leaders on Wall

Street, an expanding but still limited cohort.

A graduate of the University of Oregon's Lundquist College

of Business and CFA charterholder since 2004, she was also the

CEO and president of Women in Financial Markets, a non-profit

aimed at elevating women in the sector.

"She was someone who was laser focused on getting a job done

but always found time to offer anyone support and to mentor the

next generation of leaders," NYSE President Lynn Martin said in

a LinkedIn post on Monday.
