The accounting industry is headed for a major shift in the next several years due to the statistic that seventy-five percent of the existing CPA’s are expected to retire within the next decade.  Couple this statistic with major tax reform and technological advances, finding a seasoned accountant with the experience of Ms. Boonin is invaluable to both individuals and businesses alike.
