Overview

Of all the referenced Criminal Charges the most devastating are sex related offenses. If you are charged or convicted with a criminal offense involving sexual assault or the creation, distribution, or possession of child pornography, your life will change forever. The possible lengthy imprisonment and sexual registry will limit your movement, employment, places to live, family ties and community reputation. We have represented medical professionals, lawyers, construction workers, retirees, adolescence, individuals from all stations in life. In many instances we have been able to obtain a dismissal, reduction, and or acquittal of charges. If necessary we have the number one forensic experts in the nation to help us sort through the cyber-crime allegations to find the truth. Our mission is to protect our clients from the devastating consequences of all crimes including sex crimes.

How do I choose a lawyer?

Consider the following:

Comfort Level – Are you comfortable telling the lawyer personal information? Does the lawyer seem interested in solving your problem?
Credentials – How long has the lawyer been in practice? Has the lawyer worked on other cases similar to yours?
Cost – How are the lawyer's fees structured — hourly or flat fee? Can the lawyer estimate the cost of your case?
City – Is the lawyer's office conveniently located?

Not sure what questions to ask a lawyer?

Here are a few to get you started:

How long have you been in practice?
How many cases like mine have you handled?
How often do you settle cases out of court?
What are your fees and costs?
What are the next steps?

Want to check lawyer discipline?

It is always a good idea to research your lawyer prior to hiring. Every state has a disciplinary organization that monitors attorneys, their licenses, and consumer complaints. By researching lawyer discipline you can:

Ensure the attorney is currently licensed to practice in your state
Gain an understanding of his or her historical disciplinary record, if any.
Determine the seriousness of complaints/issues which could range from late bar fees to more serious issues requiring disciplinary action.
