Discovered by a photographer while walking down a Colombian beach, Sofia began to receive modeling offers. Since modeling was more attractive and glamorous than becoming a dentist, Sofia decided to try her hand at modeling.

One of her biggest claims to fame was her co-hosting duties with Fernando Fiore on Fuera de Serie, a series which sent her to exotic places all over the world. Broadcast on Univision, with Sofia as co-host from 1995 to 1999, it gave Sofia American exposure and made her a star in the Latin American market.

Aside from her television work, Sofia's most recent project is her calendar, Sofia 2000, which she describes as the most daring thing she has done. She has also designed a bra for fellow full-figured women, and will appear on commercials for Bally gyms. This summer, Sofia appeared on the cover of Channels magazine and was featured in Gear.
