Our 10-Point Promise

People facing criminal charges usually have no experience with such matters and have only the vaguest idea of what to expect. To help our clients, we have developed a “10-Point Promise” that spells out how we will handle your case”

  1. We do not guarantee a federal or state case result. Any lawyer or law firm that does is not being honest. The results we discuss are 100 percent the results of attorney Mark J. O’Brien, real, accurate and fully supported by federal court documents but they are past results. No one is able to predict the future. However, based upon our experience and our training we believe it is possible to alter a case based upon the facts and the law we are presented with in a legal case.
  2. We will provide you with an initial written sentencing analysis immediately upon hiring our law firm. This sentencing analysis will explain all of the penalties associated with state crimes, the United States Sentencing Guidelines and the Statutory Mandatory Minimums that may come into play if you are found guilty at trial or if you plead guilty and forego a trial. We employ a former United States probation officer of 26 years to assist us in this effort. You will know what we know, and you will know it immediately.
  3. We will provide you with a full written analysis of your presentence investigation report (PSI), if there is one, and if it is different from what we predicted in our initial sentencing analysis.
  4. We will file a sentencing memorandum outlining all of our factual and legal objections to the presentence investigation report (PSI) along with a 3553(a) variance analysis detailing all mitigating factors at least one day prior to your sentencing where appropriate.
  5. We provide mental health experts to assist in our defense where appropriate.
  6. We provide private investigators to assist in our defense where appropriate.
  7. We will keep you updated on your case through letters, status reports and conferences as much as possible. You will know what we know.
  8. If you desire, we will keep your family and/or friends updated on your case through letters, status reports and conferences as much as you choose. They will know as much as you want them to know.
  9. If you desire a trial, we will prepare and fight as aggressively as we can. Having first chaired 21 federal trial cases in federal criminal courts all throughout the country, we have the experience necessary to fight in trial — and also the experience of not only proceeding to federal trials, but also having won federal trials.
  10. Post-sentencing we will review with you your appellate options and give you a written form to document your choice to pursue an appeal or not pursue an appeal.
