"I've had the pleasure of hosting Castell as a keynote speaker for the 2018 CUNY ASAP Alumni Event and it was nothing short of remarkable. To work with Castell is an honor. He exemplifies the adage that "excellence then, is not an act, but a habit" as he consistently goes above and beyond in everything that he does."

~ JOEL CABRERA, CUNY ASAP

"With his profound knowledge of social change, leadership qualities and inspirational words of encouragement, Mr. Barnes, was able to fill the room with a different way of thinking and a better way of living for the future lives of our Teens.
