The following year, Van Roost became the first ever Belgian tennis player (male or female) to reach the top 10 in WTA rankings.

Another achievement for Van Roost came during the 2000 Summer Olympics in Sydney where she won the bronze medal in the women's doubles competition, partnering Els Callens.

In November 2000, Monami ended her professional tennis career when she became pregnant by Bart Van Roost, whom she divorced later in 2003.

After retiring from playing, Monami became involved in Belgian tennis in various capacities, including as a tournament director (Brussels Open) and as Fed Cup captain.

She also wrote a book titled Een Kwestie van Karakter (Tout est dans le caractère).
