    Steve is an excellent attorney and is especially skilled at OUI defense. I observed his thoughtful and skilled defense of clients and strongly recommend him.

    I can, without any hesitation, provide my strongest endorsement to Attorney Vaillancourt. I have been familiar with him and many of his clients for many years, and know him to be as capable a practitioner as can be found. Attorney Vaillancourt is utterly without mixed motivations, he stands firmly and completely in the corner of his clients.
