A Personal Approach to Building & Renovation Projects

Welcome to Tom O’Donoghue Associates. As founder/owner of this 20-year old Hamptons building and renovation company, I invite you to learn about our services and take a tour of some recent residential and commercial projects—large-scale new construction, tasteful additions, meticulous historic restorations and gut renovations—from Southampton to Sag Harbor to Montauk.

But to really understand how I work, please look at the testimonials. If they sound like they were written by friends, it’s because my client relationships always go that way. From the first handshake, I welcome frequent contact with my clients. I’m committed for the long term, providing open communication, solid planning and the highest quality workmanship.

About Tom O' Donoghue

As the company continues to grow, it remains my practice to take on only the projects that I can personally oversee. Throughout the construction process and well beyond, I’m available to my clients. I welcome and encourage them to play an active role.
