About Our Team

Nathan Hardage

President, CEO, CoreVision Network
Nathan grew up in a very segregated part of southern Georgia where drugs and gang violence was, and still is, very real. He graduated with a college prep diploma, allowing him to further his education on the collegiate level. Nathan was a sensational athlete in high school. He made the All-State and All-American team in football and earned a full scholarship to Florida State University where he studied political science and psychology. After college, Nathan messed up an opportunity to play professional football due to a life of drug dealing and chaos. After years of living a roller coaster life, and nearly losing his life several times, Nathan returned to the world of drugs and chaos, but not in the same form. Through his belief system and great people around him, Nathan has transformed his life and is leading others on that path.

Before Nathan became certified, he had already helped over 60 people with addiction. His philanthropic ways had also taken people off the streets and given them a place to live and a warm meal. He realized that what he was doing was his calling and life mission. Nathan invested over $160,000 dollars, last year alone, in resources and his own funding to help others. Nathan has become known as the Drug Recovery Coach and founded The Drug Recovery Network. Personally he has helped hundreds and indirectly he has helped thousands with his work and contributions though drug and alcohol addiction and recovery. Nathan has been a huge advocate and advisor for many suffering from drug and alcohol addiction.

Nathan’s Mission

Nathan’s mission is simple, when asked about why he does this, “I do this because no one else will and I feel the calling to help others. Though I am sometimes misunderstood, my main goal and purpose is to be hope and a voice for a person in need. I am trying to serve those that are lost, just as I have been. Everyone wants better for themselves, but some of us just need a reason to believe that there is hope and that we can be something better.” After living a life of turmoil, Nathan committed his life to helping others that suffer from addiction. He is a certified Drug and Alcohol Recovery and Addiction Coach and Interventionist. He has years of experience in the addiction field and is one of the top rated addiction minds in his vocation. People from all over the world call him for advice and help. Nathan has chosen to use his struggles throughout life to show others the door to freedom.
