Our Best Cities for Successful Aging initiative is about more than just rankings. It's about change. Changing policies and practices to promote healthy, productive, and purposeful aging requires transformative work and collaboration with a broad range of like-minded individuals and institutions. Many have helped. I'll recognize just a few of them here.

First, I want to thank my research colleagues, Anusuya Chatterjee and Jaque King, for their project design, research, analysis, and authorship of our "Best Cities for Successful Aging" report. Their work improving aging lives is important and impactful. Thanks to Sindhu Kubendran for her valuable research assistance. Thanks to Zach Gassoumis, Caroline Cicero, and Mollie Grossman of the University of Southern California Davis School of Gerontology for their research support as well. My appreciation to Ross DeVol and Perry Wong, also of our research group, for their support of our Best Cities for Successful Aging work from our first conversations about the initiative.

Thanks to Conrad Kiechel, Jeff Monford, and Melody Yuan for their communication support, and the members of our executive staff, including Shantika Maharaj and Fran Campione, who provided valuable assistance in this effort. My appreciation to Rita Beamish for her skillful and insightful writing assistance, to Edward Silver for his sure editorial hand, and to Jane Lee for her creative design work. Our Best Cities for Successful Aging ( and Best Cities for Successful Aging Mayor's Pledge ( websites depend on the ideas and expertise of our information technology and creative services groups. And many others at the Institute help us advance this work in their own ways.

This year, we initiated our Mayor's Pledge project. We're gratified that so many forward-thinking mayors across the country have taken the Pledge. Thanks to Nichole Wright for her outreach efforts to mayors and city leaders, and to Kathleen Helppie-Shipley, Monique Midose, and Taylor Booth for their terrific work raising awareness and support for the Pledge.

Special thanks and appreciation to the extraordinary leaders who serve on our Best Cities for Successful Aging Advisory Committee. Their advice is invaluable, and their good work on behalf of older adults and others across the age spectrum inspires hope for a brighter future.

I want to acknowledge and express my deep gratitude and the appreciation of all involved to our Best Cities for Successful Aging supporters, the Robert Wood Johnson Foundation, AARP, and the Transamerica Institute for sharing their resources, insights, and ideas. We could not do this work without their assistance. Finally, let me recognize and thank the John Templeton Foundation for our continuing collaboration to elevate and enable beneficial purpose for older adults.
