Roos was scouted as a model already at the age of fourteen. When she was 18 she started working as a model, putting her studies Psychology aside, only to finish it later on.
During her career as a model, Roos lived in different cities, such as Paris, London, and Hamburg. She worked for magazines such as Elle, Marie Claire, Tatler Magazine, Cosmopolitan and clients such as Tommy Hilfiger, Mexx, Agnes B, Viktor en Rolf, Hunkemöller, Schwarzkopf, Marie Jo en Nivea. After this great adventure, she decided to finish her studies and started working as a psychologist in the model industry, guiding many models on body and self-image. Now since a few years, she is one of the founders of 2R Model Management—broadening the vision in the model industry beyond the restrictions of age, size, and ethnicity.
When Roos is not working, she enjoys spending time with her beautiful daughter and friends. Besides that, doing yoga and enjoying short holidays, are also her much-appreciated hobbies.
