About me

New Hampshire DWI defense lawyer Mark Stevens focuses on zealously defending the rights of drivers accused of DWI in New Hampshire Courts.  This is what I do.  A lot of my cases go to trial because a lot of my clients can not afford to be convicted of DWI.  When you are deciding who will represent you, you should insist on seeing real copies of not guilty verdicts in recent New Hampshire DWI cases, with docket numbers you can verify by going to the clerk's office at the Court. 


You are welcome to visit our office for a free consultation, and to see real copies of real not guilty verdicts.  Please visit my website, where you will see hundreds of successful DWI case results. 


Call today for a free consultation 1-603-893-0074.  We look forward to speaking with you.
