O’Reilly, Talbot & Okun (OTO) is a specialty geoenvironmental engineering consulting firm.
When environmental problems are more complex than you can handle in-house, turning to outside help makes sense. Since 1994, people have turned to us because of our sound technical judgment, our use of cost-effective solutions and our reputation for professional integrity.
Our work is an approximately equal mix of projects for commercial, institutional and governmental clients from around New England.
We are a small company with offices in Springfield and Westborough, Massachusetts and Manchester, Connecticut.
