Comei, who joined TIGER 21 in 2013 as a membership assistant, is now the point person for the more than 300 members across North America, while managing 28 group meetings around the country each month. Before joining the network, Comei worked at Unum Group as a senior disability benefits specialist, handling individual disability claims.

Earlier this month, TIGER 21 launched a new group in Boston, MA, led by James Cornell, managing partner of the Boston-based private investment advisor and asset manager, Fiduciary Wealth Partners.
