With Mr. Harrington's diverse experience and education, he offers a "big picture" vantage point. "I
can bring multiple disciplines to the table to solve many of the issues people face. In particular,
people do not have the luxury of making an additional appointment, getting other professionals up
to speed on the issues, and then the client left serving as referee to make the solutions offered
come together. Many issues/disciplines, especially legal and financial, largely intersect and are
critical to solving the client's issues."
