About Us

In 2002, a group of highly-skilled and experienced property professionals established a boutique real estate investment and advisory firm in Dublin, Ireland. In the years since, we have evolved into a multi-disciplined team that work on complex projects in Ireland, the USA and the UK. While we have grown to acquire and fund over €3 billion worth of property in an ever-changing industry, we remain dedicated to the same thing as we have from day one – the personal touch.
