Naomi Feil, Founder

Naomi Feil was the developer of the Validation method. She was born in Munich in 1932 and grew up in the Montefiore Home for the Aged in Cleveland Ohio, where her father was the administrator and her mother, the head of the Social Service Department. This unique background gave her insight into the world of very old people. They were her neighbors and her friends growing up.

After graduating with a Master’s degree in Social Work from Columbia University in New York, she began working again at the Montifiore Home, where she grew up. Between 1963 and 1980 Naomi developed the Validation method as a response to her dissatisfaction with traditional methods of working with the severely disoriented old-old people who were her clients.

In 1982 she published her first book, Validation: The Feil Method. Her second book, The Validation Breakthrough, was first published in 1993. Feil and her husband have made many films and videos about aging and Validation. In her career, Naomi delivered over 1000 workshops in North America and 1000 workshops in Europe, Asia and Africa. Naomi died on Dicembre 24, 2023. Her legacy lives on in the Validation Training Institute.

Tamorra Sims, Executive Director

Tamorra serves as the Executive Director of the Validation Training Institute and lives in the United States. Her career in aging services began with her Gram Gram (Grandmother), the first person who showed her the power of presence and connection with older adults. Professionally, she started as an Activity Director and advanced through multiple leadership roles in senior living, including oversight of memory care operations, program development, training, and organizational partnerships. Over more than a decade, she has created and scaled dementia-specific engagement models, led teams across diverse communities, and strengthened quality-of-life programs through both operational and relational lenses.

Her calling is to connect, communicate, and honor the emotional world of older adults. At VTI, she is dedicated to expanding access to the Validation Method, strengthening partnerships, and supporting practitioners, caregivers, and organizations worldwide as they bring empathy and dignity to individuals living with cognitive change.
