Some of the strongest leaders don’t find their voice at the peak of their success. They find it in the moments when everything starts to fall apart. Shaped by humble beginnings, hard lessons, and a constant awareness of the paths he didn’t want to take, Dr. Keith “KC” Castille’s rise to Chief Master Sergeant was built slowly through mentorship, self-discovery, and a growing understanding that leadership isn’t about rank, it’s about responsibility. Behind the uniform, though, were deeper struggles. Loss, grief, and the weight of raising three sons on his own brought him to a breaking point that forced him to confront something he had spent a lifetime avoiding.

In this episode of the Tango Tango podcast sponsored by CareSource, host Lloyd Knight sits down with Dr. Keith “KC” Castille, CEO of C2H LLC, for an honest, unfiltered reflection on what it means to lead when you’re hurting. Together, they move through the defining chapters of KC’s life and the quiet battles that followed him along the way. KC shares the moment he realized he needed help, the decision to seek it, and how that choice reshaped not only his life, but his understanding of strength. They explore the realities of military transition, the loss of identity that can come with it, and the uncomfortable truth that success on paper often hides personal struggle beneath the surface.

Today, KC is channeling those lessons into something bigger than himself. Through his company, C2H, and his work across the veteran and global community, he is focused on helping others connect logic with empathy, performance with purpose, and leadership with humanity. His mission is simple, but not easy: to make sure people don’t have to struggle alone, and to remind them that even in the hardest moments, there is still a path forward.

Purpose can be forged in the most unexpected crucibles. From growing up as a homeschooled "Grady baby" in Atlanta's South Cobb area to serving as an Army infantry officer deployed to Afghanistan with Special Forces, Zack Knight's path took him through the grind of blue-collar work, the discipline of law enforcement, the chaos of combat, and the depths of his own personal rock bottom, before finding healing and a renewed sense of mission.

In this episode of the Tango Tango podcast, host Lloyd Knight sits down with Army veteran, entrepreneur, author, and ATLVets founder Zack Knight. Despite sharing a last name, the two are quick to clarify they're not related, though they've become close brothers in the veteran community. Zack reflects on his Atlanta upbringing, his years with the Smyrna Police Department, his decision to join active duty at 28, and his deployment to Afghanistan in 2019 where his unit lost six soldiers.

They discuss the physical and mental toll of combat and Zack’s spiral into survivor’s guilt and a near-fatal crisis. From that low point, a friend’s simple challenge sparked a transformational self-discovery. Zack also shares the unconventional healing practices that helped him rebuild, from Emory's outpatient therapy program and daily gratitude rituals to teaching himself piano with a partially numb hand. Today, he channels those hard-won lessons into ATLVets, a nonprofit now operating in 12 states, focused on giving veterans the continuity, community, and "now what" they need to thrive in post-service life.
