Brooke 's father Sidney Garber loved beauty, grace and elegance. The son of a watchmaker, Sidney opened his eponymous jewelry store in 1946. Brooke played with the charms on the floor in front of the safe as a toddler. She stood behind the counter as soon as she could see over it. By the time Brooke was a teenager, Sidney Garber was an elegant boutique on Chicago’s Michigan Avenue. Sidney instilled in his daughter his love of creativity, possibility, detail and fine execution. Brooke traveled with her father to ateliers in Paris and Milan, to the small workshops in Valenza, Vicenza and Arezzo, to the stone cutters in Idar Oberstein, and to the diamond market in New York.

While living in Manhattan with her husband and their three children, Brooke became a passionate advocate for children’s mental health, education and the arts. Today, Brooke chairs the board of the Child Mind Institute, of which she is a co-founder, is a vice chair of the board of Lincoln Center Theatre and is a trustee of the Whitney Museum whose board she co-chaired from 2008 - 2015 during the design and construction of the new Whitney Museum. In 2008, Brooke inherited Sidney Garber.

In 2015 Brooke was admitted to the Council of Fashion Designers of America and this past September she was named Contributing Editor at Town & Country. Today, the elegant business that Brooke’s father built serves an even larger mission: Brooke gives all of her profits to not-for-profit organizations dedicated to children’s mental health and wellness, to education and to the arts.
