Hedge fund billionaire Steven Cohen said Wednesday that his Cohen Veterans Network (CVN) plans to expand to 25 mental health clinics by 2020 for veterans and their family members in an effort to create the "mental and brain health care system of the future." "We've got a two-path approach -- take care of today's problems now and look for better answers in the future," he said in brief remarks at the opening of the 3rd annual Cohen Veterans Care Summit at the Ronald Reagan Building and International Trade Center near the White House.
