His principal investment vehicle was Quinlan Private, a private equity firm with offices in Dublin, London and New York.

In 2009, he resigned from Quinlan Private and moved to Switzerland on the advice of KPMG. His loans have since been transferred to Nama (National Asset Management Agency of Ireland) and various assets have been sold, including artwork from his private collection. In September, 2014, it was reported that he had reduced his debts by more than €3bn through a series of asset sales over the prior 5 years. In 2017 Quinlan returned to the European property market acting as an adviser for several deals, including one of the largest property bids in European history worth an estimated €1.3 billion.
Quinlan was born in Dublin in 1947, the son of an Army Officer. He attended Blackrock College and University College, Dublin.

In 1989 he went into private practice, founding Quinlan Private as an asset management firm for high-net-worth individuals. He specialised in investing in tax designated areas in the 1990s in Ireland supporting Irish government policy in relation to property renewal, regeneration and job creation.
