Criminal Defense

For tailored and caring representation by an experienced criminal defense attorney, turn to Robert L. Sepp, Attorney at Law. Attorney Robert Sepp serves the legal needs of his clients and has carved out a niche in the following areas:

Assault Charges

There are many factors that go into successfully defending a charge of assault and/or battery. In Oregon, assault is defined as intentionally or recklessly causing injury to someone else, intentionally placing another person in reasonable danger of physical injury or touching another individual with the intent to injure.

Domestic Violence

Domestic violence charges cover a wide variety of abuse, including spousal abuse and child endangerment. In many cases, there are specially designated prosecutors that are experienced and can readily prosecute anyone charged with domestic violence.

Driving Under The Influence Of Intoxicants (DUII)

Mr. Sepp is an experienced and aggressive lawyer when it comes to drunk driving charges. If you’ve been charged with drunk driving, it’s very important that you find a drunk driving attorney who has the experience and knowledge to guide you through this difficult time.

Measure 11

Measure 11 charges are serious felonies and carry sentences that range from a low end of five years and 10 months up to 25 years to life in prison. Measure 11 sentences are non-negotiable, and a person convicted of one of those types of crimes will serve the entire sentence with no early release or time off for good behavior.

Narcotics And Drugs

Mr. Sepp is an experienced and aggressive lawyer when it comes to drug-related charges. He has successfully protected the rights of many of his clients, getting their drug and narcotics charges dismissed or reduced.


Theft charges in Oregon are very serious. These crimes can often lead to charges in federal court. Attorney Sepp helps protect the constitutional rights of his clients facing theft charges.

Marijuana Laws

If you or someone you love has been charged with a marijuana-related driving offense, consider working with an experienced criminal defense attorney to learn more about your rights. The attorney at Robert L. Sepp, Attorney at Law, will work diligently to explore all the available avenues that will help build a solid defense.


Employers, landlords and universities commonly conduct criminal background checks. We can help you set the record straight. Oregon law sometimes allows those who have been arrested or convicted of a crime an opportunity to request a judge for an order to set aside the arrest or conviction. This is commonly known as an expungement.

Probation Violation

Violating probation results in serious legal ramifications that require the knowledge of an experienced attorney to help maneuver the landscape. Attorney Sepp has successfully handled probation issues in the Portland area for years. All probation violations need to be addressed quickly to ease repercussions.

Post-Conviction Relief

Were you recently been convicted following a trial or by pleading guilty? You may want to raise new claims as to why your trial was unfair. Consulting an experienced post-conviction relief attorney is the best way to file a petition and pursue the relief process, which may result in a new trial, a modified sentence or even release.

Sexual Crimes

Were you wrongfully accused of or questioned about a sex crime? Contact a sex crime attorney immediately. A sex crime lawyer will help protect your rights. In many sex crime cases, police officers will want to interrogate the suspect. Many who are accused fail to invoke their rights and end up making their defense more difficult. A sex crime lawyer will ensure that your rights are protected.

Arson Attorney
