Carson's business manager and confidant Armstrong Williams told The Hill that Carson won't be joining the administration in any capacity, and will serve in the capacity of an unofficial adviser.
It was reported earlier Tuesday that Carson had been offered the position of HHS secretary.
"Dr. Carson was never offered a specific position, but everything was open to him," Williams told The Hill. "Dr. Carson feels he has no government experience, he's never run a federal agency. The last thing he would want to do was take a position that could cripple the presidency."
Despite having no government experience, Carson, like Trump, attempted a run at the Republican presidential nomination in the 2016 cycle. At one point last October, Carson was the front-runner in the polls.
Carson was also rumored to be in consideration for secretary of education in a Trump administration.
During a recent interview with Business Insider just prior to the election, Carson said "I don't want to be a part of the administration."
"Not that I have anything against it," he said. "Just that, I think my voice will actually be more valuable outside the administration. There are so many issues that affect our country right now, and we can't lose sight of them. So winning the election is really just step one."
"I'll continue to write, continue to speak publicly, and work on helping to focus us as a nation on what's really important," he continued.
