About

We Build Together We build beyond expectations We build amazing places

Leon F. Driscoll started LF Driscoll under the cloud of the Great Depression, a time when reputation was paramount, and perseverance was the only lasting measurement of success. Our company built this reputation through old-fashioned hard work and dedication, which remain at our core today.

The collective talent and expertise of our people, clients, and partners have resulted in hundreds of buildings that pioneer research, advance medical treatment, and patient care, showcase art and entertainment, preserve cultural treasures, and educate generations.

Relationships are the foundation of our business
More than 85% of our work is from repeat clients—our clients count on us to deliver projects on-time and within budget. Our development and design associates know when they ask us questions, our answers are realistic and bring value. Respect for the skills and dedication of our subcontractors influences everything we do. As a result, the trust and collaboration we build with all of these partners are paramount to our success.

Top-tier construction management
Lean construction centers on teamwork and innovation as our executives, project managers, superintendents, estimators, purchasers, schedulers, engineers, architects, and virtual design & construction specialists work together. The result? Maximum value for clients through realized design for architecture and engineering partners, speed to market, cost accuracy, and safer work environments for tradespeople.

Decades of experience and leading-edge perspectives
We were managing the construction of multi-million-dollar buildings before universities even offered degrees in construction management. With decades of in-field experience—coupled with professional degrees in a variety of concentrations, from construction management, engineering, and architecture to business disciplines—our team offers top-of-class bench strength.

Diverse teams build better projects
Great ideas come from everywhere and everyone. There are no limits to what we can accomplish when we engage and empower diverse teams to employ forward-thinking construction practices and deliver excellence every day.

Safety is our core value and moral obligation
We are deeply committed to ensuring that every person who works on or visits our project sites returns home safely every single day. In support of our dedication to safety, we developed Safety 360°—a revolutionary behavioral safety program that is the new driving force in raising construction industry safety standards by instilling an inherent and consistent culture of safety awareness in employees, tradespeople, and project stakeholders.
