Sally Ko was born in Seoul, Korea in 1971. She immigrated to the United States with her family when she was two-years old. She grew up in the city and north suburbs of Chicago and now lives in Chicago. Sally attended the School of the Art Institute of Chicago and the American Academy of Art.​

Sally works in a variety of styles and media but is especially known for her style of pouring and manipulating paint to create the loose, yet controlled sensation of her paintings. The organic patterns and appearance of this variety of her paintings reflect not only the actual theme or content of the particular painting in which they appear but also the mental process that gives life to the work

Sally’s work is widely appreciated and can be found in the personal collections of a variety of clients that includes everyone from teachers to producers, executives to restaurateurs and several prominent national and international names. Her works have been featured in various magazines and have been displayed in organized shows, art fairs, corporate spaces, hotels, fashionable restaurants, galleries and international museums.
