You’ll also hear Martin’s personal story of coming to the United States from Germany as a kid, working through citizenship challenges, and how the Marine Corps helped him fast-track becoming an American citizen in 2001. Toward the end, Martin opens up about losing his father in November of last year and what it means to carry forward a 60-year legacy of spindle repair knowledge, now with Martin, his brother, and his 22-year-old son working toward a third generation.

What does it take to go from a young immigrant who barely speaks English to leading city-wide technology transformation? In this episode, Jorge Cardenas shares his powerful 22-year journey from the Marine Corps to the Department of Defense and now serving as CIO for the City of Brownsville, Texas.

Jorge opens up about how joining the Marine Corps in 2004 introduced him to the world of information technology. What started as a military assignment turned into a lifelong career in infrastructure modernization, leadership, and innovation. After eight years in the Marines and nine years with the Department of Defense, Jorge transitioned into local government and private consulting, where he saw a major gap: many companies talked theory, but few had real-world execution experience.

That realization led him to start his own technology consultancy five years ago. Today, Jorge specializes in smart city solutions, network modernization, fiber optic deployment, private 5G networks, and AI infrastructure. Most recently, he led the modernization of the entire infrastructure for the City of Brownsville, including deploying fiber optics, implementing a private 5G network, and building an AI analytics platform to create new revenue streams for the city.

What if something as common as a wisdom tooth could help heal traumatic injuries in the future?

In this episode of the Adapt and Overcome Podcast, host Tommy Hardaway sits down with Army dentist Brandi Gervais, who joins from Fort Bragg, North Carolina. Brandi shares her unique journey into military dentistry and explains how serving as an Army dentist differs from civilian practice.

Brandi talks about the group-practice model inside military medicine, where specialists work side by side and patient care is never driven by profit. She explains how military dentists can focus solely on what is best for the service member, without the financial pressure that often exists in private practice.

The conversation also dives into how Brandi’s upbringing in a military family shaped her career path, and how a simple orthodontic experience as a teenager inspired her to become a dentist. She discusses how the Army invests heavily in education, leadership development, and long-term career growth.

Toward the end of the episode, Brandi shares exciting research she has been working on involving stem cells found in extracted wisdom teeth. She explains how these stem cells could one day be used in regenerative medicine, potentially helping treat traumatic brain injuries and battlefield wounds in less invasive ways.

This episode offers a fascinating look at how military medicine is quietly driving innovation while serving those who serve.
