Rabbi Zalman Schachter-Shalomi, author of From Age-ing to Sage-ing, has inspired thousands of people around the world. Sage-ing leaders, trained to apply the ideas of this seminal book and to share these ideas with others, are working to change the way elders are perceived by others and the way older adults approach the second half of their lives.

Sage-ing International (SI) has grown from a seed planted by Rabbi Zalman Schachter-Shalomi  in  2004 for a professional association to facilitate exchange of ideas between Sage-ing Leaders and a structure for the training of Sage-ing Leaders.

Sage-ing International (SI), known until 2012 as the Sage-ing Guild and preceded organizationally by the Spiritual Eldering Institute (SEI) which served as the public face of sage-ing work for nearly two decades, has picked up where they left off, training and certifying Sage-ing Leaders and supporting Sage-ing Leaders and Facilitators.

SI has hosted four International Sage-ing Conferences since 2008,  attracting growing numbers of participants and providing  educational enrichment to  Elders around the world.

In 2011, SI adopted  a strategic plan  expanding  its focus, reaching out to those approaching or in the second half of life worldwide.The vision includes education, service and community as three vitally important aspects of the sage-ing journey.
