Sununta Prasarnphanich, a retired World Bank secretary who remained a consultant to the organization, died July 12 at her son’s home in Fairfax City. She was 66.

The cause was complications from a brain aneurysm, said her daughter, Viranand Strout.

Mrs. Prasarnphanich, an Alexandria resident, was a World Bank secretary in Thailand and Washington for 31 years before retiring in 2003. She continued to consult for the organization and worked on field assignments in Thailand and East Timor.

She volunteered with Wright to Read, an Alexandria-based educational program that promotes children’s literacy.

After living in the Washington area for more than 40 years, the Bangkok native became a U.S. citizen in 2012 so she could vote in the presidential election last year, her daughter said.

Sununta Agnes Wipuchanin received an associate’s degree in French and history from the University of Hong Kong in 1966 and a secretarial diploma from Maryknoll Commercial College in Hong Kong in 1967.

Her marriage to Vivej Prasarnphanich ended in divorce.

Survivors include two children, Viranand Strout of Alexandria and Visnu Prasarnphanich of Fairfax City; her mother, Suwanna Nancy Wipuchanin of Bangkok; five sisters; two brothers; and a grandson.
