Meet Our Founders

Abyss Construction is the brain-child of three industry veterans – Tim O’Conner, Patrick O’Sullivan, and Cathal Braonian. With 50 years of experience amongst them, they started Abyss to improve the way the construction business works. They discovered a major gap in the construction sector in terms of reliable, efficient and high-quality work.

Abyss was formed as a solution to address this gap together. Founded in the year 2016, Abyss has grown into one of the most reliable and efficient construction companies in the area.
