During the recent National Small Business Week, the volunteer business counseling and mentoring organization SCORE was recognized on its 50th anniversary. Since its founding in 1964, the organization has served an estimated 10 million entrepreneurs across the country.

Yet, says Kerry Pfrimmer, SCORE’s New Hampshire district director, the organization has not rested on its laurels and has evolved dramatically over the past decade. It is no longer your father’s or grandfather’s SCORE, as a predominantly retired executive corps has become more gender- and age-diverse, and an estimated 40 percent of the SCORE mentors in New Hampshire are still working.

Even its motto has changed from “Counselors to America’s Small Businesses” to “For the Life of Your Business.”

The 57-year-old Pfrimmer, a former top executive in the instrument and control industry who oversaw the sale of one of his former companies to General Electric, relocated to New Hampshire in 1999 and joined SCORE in 2007. He became New Hampshire director last fall.
