Cadman was born and raised in England, near Colchester, during World War II as a birthright Quaker.
PMA clients included investment banks, pension funds, and commercial developers and it became a successful international operation.
Cadman and Barras set up a PMA subscription service, PROMIS, that still provides regularly updated information on most UK and some global urban markets, currently on 300 towns and cities.
On retiring from the world of property consultancy, Cadman became more interested in philosophy and the "place of love" from which Quaker testimonies spring, and how to enact these in everyday life.
Its goals are to "bring together leaders and practitioners who hold the view that the positive energy of love is the deepest, most enduring and most valuable characteristic of human nature.
