Abacus Ark was founded in 1971 by Angela Carrington, in a small room attached to a Church on Harley Street. In 1981, her daughter, Laura, joined the nursery, and in 1981, they opened The Toddlers Inn Nursery School in St. John’s Wood, North West London. Laura’s son, Anthony, who attended Toddlers Inn Nursery School, went on to study at Durham University, where he earned his bachelor’s and a master’s in Mathematics before beginning a successful finance career. During a spell of volunteering at Toddlers Inn, Anthony decided to leave his career to begin Abacus Ark with his Mother. The duo has since been delivering quality early childhood experiences.
