Collaboration Opportunities

What are the benefits of being a Protégé?

  • Opportunities to develop skill sets that can complement or diversify the protégé firm.
  • Build trust and loyalty between the mentor and protégé.
  • Additional mutually agreed upon benefits from mentors including work that flows from a government or commercial contract through subcontracting or teaming arrangements.

Navigate to Mentor Protégé for more information.
