Nina is fortunate to have developed many wonderful relationships with older adults, starting with her own grandmothers. These experiences shaped her in many ways and inspired her decision to focus on healthcare and health related issues affecting older adults throughout her career.

While working at Age Wave IMPACT, the nation’s leading research and marketing firm focused on older adults, Nina learned about the difficulties that adult children often face in fulfilling the needs of their aging parents and keeping up with their own family and work responsibilities.

She decided to earn her master’s degree in gerontology and became a professional geriatric care manager. Today at Sage Eldercare Solutions, she strives to empower people to make wise eldercare decisions, relieve family caregiver worries, and help older adults live better.

Nina holds a master’s degree in gerontology from San Francisco State University and earned a certificate in Professional Fiduciary Management from California State University at Fullerton.
