Angela Collins O'Mahony came from a small farming background and originally worked as a secretary for a steeplejack company. One day she was sent to a site to deliver materials and, when she couldn't attract the men's attention, she climbed up to the top of the chimney stack to tell the steeplejack's that their materials were there.

With that Angela's life-long passion for climbing was born. She went on to establish her own business, which eventually employed 62 people and allowed her to work with a major American company. Even when she was the Managing Director, Angela still scaled 300-foot high church spires to replace blown-off crosses, and 600-foot industrial chimney stacks. 'Steeplejill' is the remarkable story of this remarkable woman.
