There are no celebrity guests on the Schafer team. While we believe in the star power evident in the line-up of experts on our team, it stems from their willingness to roll up sleeves and deliver their expertise rather than rest on laurels. When a customer hires us to do the job, the A team shows up for work. And when additional astrophysicists, astronautical engineers, probability experts or statisticians, space systems engineers, computer specialists, advanced analysists, or any other specialty is needed in greater numbers, we reach across Schafer’s legendary rolls or engage our corporate recruiters and staffing professionals to fill the gaps.
