The FourBlock Podcast

Jan 13, 2020

Duty-Honor-Country. This week, we welcome Citigroup Managing Director and retired Army Colonel John Tien. John is a first-generation American who felt a duty and obligation to serve the country that provided so much for his family. He ended up serving for 24 years, which included three combat tours to Iraq and three tours in the White House serving Presidents Clinton, Bush, and Obama.

John discusses his incredible service, the impact of his time in the Army on his family, and the similarities and differences between leading troops in combat and teammates at Citigroup. If you are a civilian seeking to better understand military service or a veteran trying to learn how to most effectively transition military leadership principles to a corporate environment – this is a must-listen episode! 


Welcome to the FourBlock Podcast, a show that examines veteran career transition and the military-civilian divide in the workplace.

General Charles Krulak coined the term "Three Block War" to describe the nature of 21st-century military service defined by peace-keeping, humanitarian aid, and full combat.

But what happens next? Veterans are often unprepared to return home and begin new careers. We call this the Fourth Block. 

FourBlock is a national non-profit that has supported thousands of transitioning service members across the nation in beginning new and meaningful careers.
