Berny Lenferink was born to Wijlen Antonius January Lenferink and Wilhelmina Maria Boswerger in a family of nine siblings. During that race she broke a bone in her foot, which hindered her training through 1968–1969. On 23 December 1970, Lenferinke married Leo Boxem and changed her last name to Boxem-Lenferink.
She retired from athletics shortly after the 1972 Olympics, aged 24, due to lack of motivation.
