Our Story

For over 36 years, Kim Mitzo Thompson and Karen Mitzo Hilderbrand, known as The Twin Sisters®, have been writing and producing educational and inspirational products that use music to teach children basic skills. Starting out with just one album “Rap With The Facts—Multiplication,” written for Kim’s third grade students to help them memorize their facts, the twins decided to form a record label in 1987. Together they have led their company through dynamic changes in the music and publishing industries.

With over 80 million albums sold, and over 180 national awards, including nine Record Industry Association of America (RIAA) certified gold albums and one Platinum album for educational excellence, creativity, and overall classroom and family fun, Twin Sisters® positions itself as the leader in children’s educational music.

The Twin Sisters® have been members of the Chicago Chapter of the Recording Academy and voting members since 1992. They believe in the Academy’s mission of fostering artistic and technical excellence, preserving historically significant musical works, and reaching young minds through the GRAMMY® Foundation.

Twin Sisters® Digital Media releases thousands of products each year including digital albums, eBooks, videos, audiobooks, teacher resources, and more. These dedicated business owners are focused on creating and licensing exceptional products for worldwide distribution.
