She studied in Paris, France and exhibited at many group and solo shows including at the Pennsylvania Academy of Fine Arts, Salon des Tuileries, Salon d'Automne, the Brooklyn Museum, Arts Club Washington, D.C., and at many galleries in New York City.

Crooks was the subject of a painting by Ary Stillman, a Russian American artist, who also spent time in Paris.

His painting, Portrait of Mrs. Pinckney Daves, was exhibited in late 1931 at the "L'exposition Artistique la Plus Originale de L'Annee" at Salon des Echanges.

Another reviewer at The New Yorker can't decide if Crooks's nudes were the high-spot of the show, but claims to like them immensely.

The featured artwork in an article in Elle Decor Magazine (May 2023), "Bring the Drama," is a large abstract painting by Mildred Crooks.
