Jon McElroy

Managing Director

Jon McElroy

Since joining Mace in 2006, Jon has been involved in many of the company’s highest-value projects – he initially joined Mace to lead the commercial delivery of The Shard and now leads our International Technology business unit as Managing Director.

Jon is particularly skilled in complex and risky schemes, tackling the issues that others find challenging and providing contractual and cost certainty even in challenging circumstances.

Jon is a natural problem-solver, and that inherently goes hand-in-hand with the higher-risk projects. He enjoys a challenge, and picking his way through a complex set of circumstances. Similar issues will arise in the industry, but the solution and approach will almost always need to be slightly different.
