In September 2003, with 20 thriving infant/toddler, preschool and school-age centers in the SF Bay Area, MDS engaged Bright Horizons Family Solutions to provide management services to MDS programs.

Relationship between MDS and Bright Horizons — After many years of getting to know each other and developing mutual respect, MDS engaged Bright Horizons to help manage the MDS programs. Both MDS and Bright Horizons share a strong commitment to high-quality education and meeting the needs of children and families. By engaging Bright Horizons to provide management services for its programs, MDS benefits from the expertise and resources needed to support and maintain the quality of these programs. Support from Bright Horizons includes human resources and recruitment, education curricula and teacher training, financial planning and reporting, information technology, and risk management, and allows MDS to operate its programs in a fiscally responsible manner.
