As a former Assistant U. S. Attorney and Trial Attorney in the Justice Department for nearly 30 years, I investigated, tried and handled appeals in white collar crimes and other cases, including violent crimes in Indian Country. On the defense side, I have represented individuals in the investigation, trial and appeal of these types of cases. Based on my many years of practicing on both sides of the aisle, I have determined that complex criminal defense matters turn on an attorney’s ability to analyze detailed evidence and sophisticated legal issues, put together a cogent defense and make sure the client understands what I and my team are doing and why. This means that the client is intimately involved in building his/her defense. It also means enlisting the right support services, such as experts in the nature of the crime alleged, investigators who can work well with people, are meticulous and resourceful.

Often, a prosecutor’s best weapons are intimidation and a defendant’s inability to understand how the evidence collected by the government will play out before a jury. In the course of thoroughly investigating the case through document analysis, witness interviews and background checks, my team and I test the government’s case against what we have found. In a white collar case, I typically employ CPAs, forensic accountants, and experts in the area of inquiry, such as crypto currency, computer analysis or mortgage review. All of this effort is shared with the client. My team and I sit down with client over a period of time to address all issues, factual and legal, to arrive at a plausible defense. At times, this includes developing mitigation, or answers or explanations, for evidence that appears damning to the client.

No matter how difficult or embarrassing a client’s situation might seem to be, I treat every client with the respect and dignity they deserve.

I welcome a review of the criminal cases I have handled over the years, including those listed on my resume. I also welcome a review of testimonials that clients have offered:
