In March 2018 Capstone Legal and Koroneos Lawyers merged to form Capstone Koroneos Legal. The merger was the result of a desire to provide a wider range of legal services to their clients and shared values of prioritising client relationships over profit.
As a result, Capstone Koroneos Legal is a commercial practice that offers highly personalised and meaningful legal advice on a range of finance, property, commercial advice, insolvency and commercial litigation matters.
