David Paul Flanagan

About me

As a criminal defense lawyer with nearly a decade of legal experience, Attorney Dave Flanagan has brought forth fair cases and trials for those facing everything from arson to DUI charges and everything else in between. In the early years of his career, he worked as a private investigator for an insurance provider. This allowed him to learn how to competently and accurately discover inconsistencies and pertinent evidence that are essential to the success of a case. Mr. Flanagan trained in various techniques that have proven to be useful in his current position in the field of criminal defense. Having to aggressively present factors and utilizing creative tactics in the past, Attorney Flanagan is more than qualified to handle any and all criminal charges. He works personally with each of his clients from beginning to end, always keeping them informed on the progress of their case.
