Client Testimonials

Excellent representation in expungement motion, highly recommended!

Based on my experience working with Mark and his team, I highly recommend him. In 2011 Mark successfully represented me in a motion to set aside a conviction for possession of controlled substance in Oregon. I chose him after consulting with a total of three lawyers on their legal interpretation of the case and cost for their services. Mark noticed details about my case and their potential significance that the other two lawyers completely overlooked, and his fees were lower as well. Mark and his team kept me informed throughout the process and made filing the motion a simple matter.

When the DA opposed my request for expungement, Mark successfully argued the case to a judge and won the motion, removing this conviction from my record. He did all this without my needing to appear in court. I was extremely impressed with his intelligence and legal knowledge, and with the customer service he and his team provided. I would recommend him without reservation to anyone planning to seek an expungement.

Relief most welcome after 25 years.

Mr. Cogan represented me in an application/petition for relief from sex offender registration responsibilities here in Oregon. I had served my time in another state many years ago, but recently moved to Oregon. I was required to register in the other state as well as Oregon, which I did conscientiously. Mr. Cogan advised me after a thorough review of my court and rehabilitation documents, that I met the criteria in Oregon to apply for relief from the registration requirement. He did superb legal research and preparation before the hearing. Thanks to Mark, everyone agreed with my rehabilitative efforts, and that I wasn’t a danger to society. At the hearing he was persistant in his legal arguments, and I was able to receive a positive outcome.

Great lawyer!!!

Mark did a great job representing my family and me through a very tough case and was very helpful in getting a great result and making sure that everything was taken care of. He was very efficient and tactful and always seemed like he knew what he was doing!!! I would highly recommend him to anyone who had a difficult case who needed some good help and representation.

Highest Commendation

Finding yourself on the wrong side of the law is positively terrifying–the arrest, the handcuffs, the mugshot, the fingerprints, the 5-hour lockup, the formal charges . . . need I say more? Every step is excruciating. Your life is upside down, and it is phenomenally challenging to think clearly.

At this juncture you need the best Criminal Defense Attorney available, one who is equally adept at providing a defense as well as an offense. Mark Cogan does both, and he does so vigorously, aggressively and methodically. Mark understands and maintains the proper balance of defense and offense with a laser focus. If you think this sounds important, you are completely accurate. It is so critically important, in fact, that it is the difference between success and failure.

I cannot recommend Mark Cogan more highly.


Mr. Cogan obtained for me, an Expungement of my criminal record.

The research required, far exceeded his expectation. Yet the service was completed for the compensation agreed upon at the outset.

I am Very Grateful for the efforts he made on my behalf.

If there were a category for, Most Excellent! I would have marked it.

Ms. 5.0 Stars

Mr. Cogan assisted my son to expunge his felony criminal records. My son was barely 18 when he committed these offenses. He learned a very hard lesson as a result of his actions. Mr. Cogan successfully defended him to get his records expunged. He responded to my questions and concerns even during weekends and during his vacation. His dedication to serving and defending his clients are extraordinary. Now my son can move on with his life after 10 years of suffering from a criminal records. He has a good job with Apple Computers and is able to contribute his skills and talents to society. Thank you, Mark. We are grateful to your services and would highly recommend you to our friends and family members who might need your assistance and support.

Absolutely The Best!

I went back to my rating and made one change. Originally I only gave him 4/5 on responsiveness only for the purpose of trying to not give a reader the impression that I was just “gaming the system” by giving all high marks, but then I thought to myself that I could not under rate him on his responsiveness. Not only was he always available but I can not think of a single time that I could not get a hold of him or get documentation in an untimely manner. I mean it when I say I can sleep easier at night knowing that someone like Mr. Cogan is out there protecting our legal system from abuse.

Excellent Attorney to Refer Your Clients To

I have both referred people to Mark who have always been very happy with his work and I have twice personally hired Mark to assist family members with legal matters. Highly recommended.
