“With the acquisitions of The Lanyon Group and Blue Lake, and the leadership of John Herlihy, we are uniquely positioned to provide unparalleled advisory services across Ireland, the UK and into Europe.
“Our mission everywhere we operate is to help the best in the world be even better, and we have brought together a team with the ability to do just that.”
The company also announced the appointment of other senior leaders to the business, across a team of 30 in total.
Mr Herlihy added: “I’m thrilled to join Consello at such an exciting time. Ireland is rapidly evolving as a hub for innovation and growth in the region, and Consello’s combination of global expertise and local insights will provide businesses here with the strategic counsel they need to succeed.
“I look forward to working with Declan and the incredible team we’ve assembled to drive meaningful impact for our clients.”
