I have practiced as a criminal defense attorney since 1982, successfully representing clients facing the entire range of criminal charges, from misdemeanors to the most serious felony prosecutions.
I graduated from one of the top 5 law schools in the country, and trained with the best criminal defense attorneys at the National Criminal Defense College.
I established my own criminal defense law practice in Oregon in 1997, and have worked continuously to defend clients in both State and Federal Court. I currently represent clients facing a range of felony and misdemeanor charges, including major sex crimes, financial crimes, driving offenses, controlled substance prosecutions, domestic violence matters, firearms matters, and Ballot Measure 11 charges.
As the owner of a 4-attorney law firm, I take personal responsibility for defending all my clients. When appropriate, I include other professionals in my defense team, including investigators, scientists, forensic psychologists, polygraph examiners, and other attorneys. I have been granted the highest professional recognitions, and am available to take on additional matters.
Our multilingual staff includes professionals who are fluent in Spanish, Russian and Arabic, and we frequently use outside contractors to interpret for our Vietnamese and Chinese speaking clients.

I left a voicemail for Mr. Cogan late in the afternoon. I expected to be ignored, because no other law firm had bothered to return my call regarding my child being cited with an MIP (Class B violation), and, juvenile law in Oregon. I haven’t had a need for an attorney ever, and therefore I didn’t k...
Thank you for your kind words. We get enormous satisfaction assisting people. We invite you to get back to us if you have further need for assistance.
"Mark Cogan is one of the most respected criminal defense attorneys in the legal community. He is always willing to share his knowledge and expertise, and I have achieved outstanding results for my own clients on account of his advice and support. His experience and dedication are incredible assets to his clients, and I would certainly recommend his services to anyone facing a serious criminal charge."
"Mark is a superb defense attorney dedicated to the vigorous representation of his clients. I recommend him without hesitation."
"Mark has been practicing criminal defense for more than 40 years, and it shows in his knowledge and skill. Being on his team is an absolute honor. He is a dedicated and zealous advocate, and the team he has assembled emphasizes his dedication to the ethical expectations of counsel and beyond. If you ever have the opportunity to work with Mark, take it, and learn from his experience."
"Mark C. Cogan has turned an exemplary legal career into a brand name. His law firm handles many cases that have serious criminal implications all over the state of Oregon. He treats his business as a family and cares about the well-being of his employees as much as he cares about the well-being of his firm. I was fortunate to work at Mark C. Cogan PC for a year and a half. In that time I learned much about criminal defense and the legal profession directly from Mr. Cogan, which is unheard of in most other firms. Rarely do you get to be mentored by the man whose name is on the door. Mr. Cogan is a class act who takes a holistic approach to criminal defense, leaving no stone unturned. His knowledge and experience speak for itself, not only in his own legal career, but by the attorneys and staff that he brings into his family. You are in good hands with Mr. Cogan and the Cogan Law Office."
"I enthusiastically endorse Mark, our esteemed founder, known for his exceptional reputation in the criminal defense community. Mark's unwavering commitment to justice and profound understanding of criminal law set him apart as a standout advocate for our clients. His strategic approach and empathetic communication consistently lead to positive outcomes. As a great boss, Mark's supportive leadership significantly contributes to our team's success. Mark's outstanding reputation is a testament to his expertise and unwavering commitment to his clients."
"Mark is a kind and gracious attorney dedicated to his craft. He went out of his way to help me while I was preparing for a difficult Measure 11 case. I truly look forward to the next time that we cross paths."
"Related to my criminal defense practice in Montana, I consulted with Mark on an issue of Oregon criminal procedure. He is knowledgeable and was very helpful. I will recommend Mark without hesitation."
"I wholeheartedly endorse Mr. Cogan as a criminal defense lawyer and can describe the extent to which I trust his competence and judgment as follows: I have known Mark for nearly 25 years and have practiced law alongside him for those 25 years, in the same fields. I have referred countless cases to him and his results are superb, his clients are always well served and he is a colleague whose advice I rely on weekly -- and sometimes daily. Endorsement is really not a strong enough term to describe my respect for Mark's ability as a lawyer, advocate and counselor."
"Our office collaborates with Mr. Cogan and his team. Mr. Cogan is a trusted colleague and a highly respected member of the legal community. He is knowledgeable and is a strong advocate, committed to protecting his clients rights."
"Smart, competent, hard-working. Mr. Cogan is an excellent attorney, and does not shy away from a fight."
"Mr. Cogan is a well-respected, highly competent attorney. If that were not enough, he is also professional, patient, and dedicated to obtaining the very best outcomes for his clients. Mr. Cogan is the attorney that other attorneys send criminal cases to, and I would not hesitate to recommend him."
"Mark Cogan is smart and very experienced. I have referred several serious matters to him that require the highest level of professional care. He ranks as one of the best lawyers in Oregon."
"Attorney Cogan has a well-deserved reputation for using his training, experience and guts to minimize or eliminate the consequences that a citizen accused faces. In working together on a matter, I can see first hand how he is diligent and experienced. Most importantly, he has guts. He stands up for what is right. He is trustworthy. I trust him. I know you will too."
"Mr. Cogan is well known as one of the best defense lawyers in the Oregon bar. The Avvo rating is not always a reliable guide to an attorney's quality, but Mr. Cogan deserves his perfect rating 100%."
"Mr. Cogan is a master in his field. He is very conscientious and dedicated to defending the rights of the accused. Our profession needs more attorneys like Mr Cogan."
"Mark Cogan has that perfect combination of tenacity and compassion to guide you from trouble to triumph when facing criminal charges. He has three decades of impressive experience, and truly cares about his clients. He's that rare find who will know exactly how to handle your case, will put you at ease, and will fight as aggressively as he can. Having had the opportunity to meet him, I now look forward someday to working with him, and endorse him without qualification for anyone ensnared in the criminal justice system."
