Local Impact & Global Vision
A founding partner at Lissah & Boyle, David is an accomplished Chartered Manager and Management Mentor, with a Safety Compliance Specialist background, and a 30 year career built from the shop floor to the boardroom. He has worked in multiple environments from military, facilities management to creating inclusive communities in sports and recreation. 
"Everyone deserves to be led well and work in a psychologically safe environment where they can contribute their best. As Vice Chair of IIRSM Ireland and Committee Representative for Northern Ireland, my mission is to equip managers globally with the tools, resources, and support they need to build safe, engaged, and resilient teams." 
As a Partner at Lissah & Boyle, David leads a fractional business support team that helps business owners, executives, and managers overcome the real-world challenges that hold back performance. Many already have the talent and technical skills, they just don't have the time, resources, or capacity. That’s where David comes in. 
Whether it’s mentoring and unlocking productivity challenges for managers on the shop floor or as an accountability partner for executives, delivering on their strategic aims, David helps clients transform operational friction into focused execution. 
Life Outside of Business
When David is not working with small business owners or mentoring future leaders, you’ll most likely find him with a canine friend by his side. He is a passionate dog lover and proud foster carer, providing temporary homes and a bit of extra love to dogs in need.
David is also a volunteer with the Mid Antrim Animal Sanctuary, a cause close to his heart. It’s more than just giving back; it’s about showing up for those who can’t speak for themselves, and helping them find safe, loving homes. 
These moments away from the desk are the things that recharge David, keep him grounded, and a reminder why empathy and resilience matter just as much in life as they do in business.
