David Ayala

David Ayala is celebrated as a leader in the restoration of voting rights and champion for the people. He worked tirelessly on the Florida Second Chances Campaign which resulted in the restoration of voting rights for over 1.4 million citizens in Florida. David served as the first President of Florida Rights Restoration Coalition’s Central Florida Chapter, created the first chapter of its kind, and set the standard for communication and education for all 20 chapters that followed.


Although he currently has a successful and flourishing career, David is no stranger to adversity and overcoming obstacles. He went from being a young child making bad choices in his hometown of Brooklyn, New York to a strong advocate and champion for others. He has credited his success to his personal understanding of the challenges that plague poor, black, and brown communities. 


David holds an Associates of Arts degree in Business Administration from Valencia Community College, a Bachelor of Science in Non-profit Management from the University of Central Florida and is en route to a Master of Science in Non-profit Management, also from the University of Central Florida.  In his current capacity he serves as the National Organizer for the Formerly Incarcerated Convicted People and Families Movement/FICPFM, where he focuses on mobilizing directly impacted communities across the country in support of civic engagement and advocacy campaigns to end mass incarceration policies. Prior to his national work with FICPM he worked as a State Organizer with Latino Justice building coalitions across the state of Florida. 


David has been happily married to his wife Aramis Ayala for over a decade, and he is a proud father to their daughters Aliyah and Alanah. While he is passionate about criminal justice reform, in his free time he enjoys running, watching movies, and simple quality time with his wife, their daughters, and his son. David is an active member of his church, Rejoice in the Lord Ministries.
