We have reached an important chapter in our history: our sixtieth anniversary. Since the partnership of Earl F. O’Brien, William S. Gere, and Glenn D. Holmes in 1945, we have distinguished ourselves through strong client relationships, technology and innovation, and a passionate entrepreneurial spirit. Now, more than half a century later, O’Brien & Gere has evolved from a simple collaboration of three engineers focused on local water and wastewater projects, to one of the oldest and largest employee-owned engineering and project delivery companies in the nation. 

We have changed considerably since 1945. In the 70s and 80s, O’Brien & Gere diversified its services to help clients address the complex challenges of environmental issues while improving productivity in an ever-increasing, competitive global marketplace. In the 90s, O’Brien & Gere recognized the benefits of a total, integrated project life cycle approach – from scientific services, design, engineering, and construction to operations and maintenance services. The firm established a remarkably strong base of Fortune 500 clients, major municipalities, federal agencies, and distinguished academic and medical institutions. The result is a company that provides 360-degree engineering and project delivery solutions. 

While O’Brien & Gere continues to evolve, our philosophy has remained the same since day one: to conduct our business with absolute integrity, and to establish the safety, satisfaction, and dignity of our clients, employees, and the public, above all else. Ours is a company committed to excellence, evidenced by our long track record for innovation and client service. Our passion for ingenuity, coupled with our commitment to delivering consistently high-quality services, is the reason O’Brien & Gere, one of the oldest employee-owned engineering and project delivery companies, is thriving today at sixty.
