Mark Ward (Mark)

Mark is a former British police detective who founded a crisis management and investigations business.

He utilises his experience in law enforcement combined with his business and private sector knowledge to manage risk for people in the High Profile and High Net Worth and Corporate worlds. During the covid lockdown of January 2021 he was approached by John Clare to assist with a pro-bono case.

Mark and John had known of each other for several years but had never worked together. John asked if Mark could use his business and network to help find the grave of the mother of an 83 year old, who had been born in Dublin in 1938 and never known anyone he was biologically related to. Mark and John set out on a quest together with the help of numerous other key people who gave up their time for free. It was an experience that would change their lives and form a deep friendship as they found the mothers grave and to everyone’s surprise a wonderful family in Wexford and a living sister who at almost 80 years old herself was thrilled to meet the brother she had not known existed. John’s friend was sadly to pass just a few months after finding his family but had answered many of the questions of his life in the last few months. 

When someone with John’s lifetime of experience of working with some the most famous bands in world asked Mark to join Artemis it was an easy decision. The creation of the international and UK business is a fitting legacy to their friend and a continuation of their journey together.
