Gituru Secondary : Where SK Macharia was school bell ringer 4 years ago British novelist Jeffrey Archer recalled how “I was allowed to ring the bell for five minutes until everyone was in assembly... it was the beginning of power.” For successful entrepreneur SK Macharia, being the timekeeper and thus school bell ringer at Gituru Intermediary School in Murang’a, was the foundation of his success in business as Wanjiru Waithaka and Evans Majeni informs us in A Profile of Kenyan Entrepreneurs published in 2014. Gituru was a primary boarding school which SK joined from Gichagi-ini primary where he failed Class Six (after spending a whole year playing draughts with British Johnnies), and thus repeated classes at Gituru which went up to class seven.
