He tracks down witnesses, he visits accident scenes, and he does everything he can to ensure that no stone is unturned.

Attorney Kenneth Butterworth is happy to help injured workers, injured motorists, disabled individuals who can no longer work, persons unfairly charged or over-charged with crimes, and significant others in domestic relationships who seek financial fairness, distribution of assets and an ongoing life with their children.

He knows that people in these situations are going up against large companies and governments. With that comes investigators, multiple attorneys, and insurance professionals who make a combined effort to beat you. Attorney Butterworth evens the playing field with his investigative skills.
