Brad Weeks
I help attorneys win impaired driving cases by identifying weaknesses, exposing mistakes, and strengthening the defense with experience prosecutors and judges respect.
Why My Experience Matters
Police have immense power and complex procedures. Mistakes happen. Important details get missed. Those errors can change the outcome of a case.
I’ve been on both sides of the investigation.
I Know OWI Investigations Inside and Out
Hundreds of investigations, DRE evaluations, and thousands of SFSTs give me a perspective most attorneys don’t have.
I Know What to Look For
From improper test administration to overlooked clues, I find what others miss.
I Provide the Truth, Not an Agenda
I’m not here to take sides. I’m here to evaluate the evidence and give you clear, honest answers.
I Help You Win
Strong analysis. Clear opinions. Effective testimony. Everything you need to put the best case forward.
Why Attorneys Rely on Me
Unbiased, Independent, Objective
Retained by your team. Guided only by the evidence.
I Know How Police Work
I understand their training, their pressures, and their habits so I know where mistakes happen.
Save Time and Strengthen Strategy
I review the case so you can focus on winning at trial.
Clear, Powerful, Persuasive
I explain complex issues in plain language that judges and juries understand.
