Board of Directors

She has two children and works from home with a Fortune 500 Wellness Company. In January 27, 2010, life changed. The Chamblees’ 21 month old daughter Sierra was diagnosed with stage IV neuroblastoma. For 11 months Gen watched her baby girl fight for her life every day, and was holding her the moment she became an angel on November 23, 2010. From that day forward Gen decided to keep Sierra’s memory alive and help so many others who are beginning the fight, or are currently fighting, by creating The Sierra Rayn Foundation.
