Before that, Ms. Blackwell was Vice President of Communications & Marketing Communications for government contractors including FCi Federal (now PAE), Decision Sciences International (DSIC) and SRA International (now GDIT).

"Communications professionals too often focus on external media relations at the expense of key elements like internal communications. Internal communications drive corporate culture and deliver value by increasing employee engagement and retention."
