THE BOSTON GLOBE - “I realized that as a practicing physician or surgeon, the absolute impact I could have was constrained by what I could do with my two hands in 24 hours,” said Dr. Samuel Levy, 35, who planned to become a medical oncologist but instead helped found Allurion Technologies in 2009 to take on the obesity epidemic. [...] Levy said he can help “patients halfway around the world while I am sleeping”.
