Sisk is delighted to announce two senior appointments from within the business at Managing Director level to help Sisk continue to grow and deliver its strategy.
Brian Comaskey has been appointed Managing Director of Sisk’s Ireland East business unit. In his new role, Brian will report to Steven McGee, Chief Operating Officer (COO) for the Sisk Construction division. Diarmuid O’Sullivan has been appointed Managing Director of a newly established Energy Business Unit, where he will report to Leo Martin, COO of the Sisk Infrastructure division.
Brian’s appointment is an example of the depth of talent within Sisk and recognises his significant contribution and commitment to the business over more than 20 years. Brian first joined Sisk in 2004 as an Engineer, working on a range of Dublin city centre projects across the Residential and Commercial sectors. He subsequently progressed to Contracts Manager, Project Director and since 2022, Regional Director.
Throughout his career, Brian has played a leading role in the successful delivery of many of Sisk’s flagship projects across a range of sectors including Residential, Commercial and Healthcare. Along the way, he has continuously built strong relationships with clients, partners and teams.
Brian Comaskey, Managing Director, Ireland East, Sisk said: “I am delighted to be appointed as Managing Director of the Sisk, Ireland East business unit. Having spent 22 years with Sisk, I can see great opportunity for us to grow and develop further in the residential and commercial space in Dublin and play a key role in the overall company strategy in healthcare, energy and infrastructure. I’m looking forward to continuing to build upon existing and new client relationships.”
Diarmuid O’Sullivan has been appointed as Managing Director of the newly established Sisk Energy Business Unit. Establishing this dedicated business unit represents an important step in re-establishing and growing Sisk’s presence and capability in this sector where Sisk has previously delivered more than €1bn in recent years.
During his time at Sisk, Diarmuid has led the delivery of complex mission critical programmes across Ireland, Europe and Africa for major international clients. Diarmuid previously led our Data Centre business and played a pivotal role in establishing and growing its capability in Ireland and subsequently across Europe.
In his new role, he will work closely with the senior leadership teams in each of our Divisions, along with our subsidiary companies Farrans and Sensori as well as our extensive industry design and supply chain partners, bringing together the breadth of capability, expertise and geographic reach that exists in the business. The new Business Unit will form part of the Sisk Infrastructure Division, with Diarmuid reporting to Leo Martin (COO).
Diarmuid O’Sullivan, Managing Director, Energy said: “I am honoured to be celebrating 34 years with Sisk, starting out in 1992 as a Graduate Engineer and progressing through a range of roles to Director for Ireland & Europe in 2020. I am delighted to be taking on this new challenge and proud to be part of this great Sisk team. I feel incredibly fortunate to have had the opportunities to enjoy such a varied and rewarding career, working across Ireland, the UK, Europe and Africa to date.
“The energy transition represents a significant long-term opportunity for Sisk, and I believe we have all the experience and capability needed to become a leading delivery partner for these vital projects. The move towards cleaner and more secure energy is creating exciting opportunities, and establishing this dedicated Business Unit gives us the leadership and focus required to build a sustainable business in this sector.”
Commenting on the appointments Paul Brown, Sisk CEO said: “Diarmuid’s and Brian’s appointments are great examples of the career opportunities within Sisk. Both have been with the company for many years and have worked their respective way up the ranks.
“I wish them well in their new roles and both will play a key part in helping us deliver on our growth strategy and to continue to deliver places for future generations.”
