About James

Learn James’s areas of practice.

I am a serious lawyer who addresses serious problems for my clients. I do it with integrity, hard work, tenaciousness and perseverance. You are not a number but a person who deserves an individual defense based on your needs and the specifics of your case. A tailored defense, the object of which is to get the best result possible.

I am a family man and understand that a criminal case does not just effect just an individual, but also their family. With that in mind, I treat you as family during and after representation. 

Yes, I have had great success, but that is in large part to the people I surround myself with and my work ethic. I would be honored to be your champion.

Great Lawyer
I couldn't have been happier with the results of my case. I found Mr Castle in a magazine titled Denver's Best Lawyers. I am glad that he ended up with me in court. Highly recommend!

Mr.Castle is and excellent Attorney, he's represented me twice in very critical criminal cases.I was facing 25 years to life in prison and to be honest I was guilty. Never the less Mr.Castle worked hard on my case and fought relentlessly on my behalf. He was prepared to go all the way to trail if necessary but secured me a life saving pleabargan of 2 to 6 years instead. After being released form prison for over 20 years I never thought I'd need Mr.Castle's services again. Never the less I was caught up in the judicial system again. After my arraignment I knew I needed an Attorney I could trust. I was facing 10 years on trumped up charges and this time I was innocent. To make a long story short Mr.Castle got on the case and got it dismissed. I am truly grateful for Mr.Castle and his team not only do I recommend him as an Attorney but I also trust him as an Attorney.

Best Attorney in Denver
Jim is the best attorney in Denver. This man has helped with serious issues and I would absolutely never use anyone else. A compassionate and very conscientious attorney.

Way above the rest!
Jim came highly recommended, and did not disappoint. My experience with Jim revealed that he is not only a very competent criminal lawyer, he also is compassionate and caring; Jim possesses a rare combination of professionalism and genuine concern for clients. I have never experienced a lawyer, and his staff, as accessible and communicative. Jim answered all communication immediately and clearly, helping me understand all the legal language and expectations of the court. All that I have experienced with Jim puts him way above the average attorney. I highly recommend him.

Mr. Castle advocated and secured an amazing outcome for me which was beyond expectations. His communication skills and knowledge of the law are excellent. I would highly recommend him for any white collar crime case.

"I endorse this lawyer without any reservations. It is amazing that I continue to learn from him every day from his responses on Avvo even though I have been licensed for 24 years and have served as a judge, magistrate, law professor, prosecutor, and private attorney. You can not afford not to hire him."

"I endorse this lawyer. I have worked with Jim on many criminal cases that had immigration implications. He is an outstanding lawyer in the area of federal criminal defense."
Criminal defense Attorney | Jun 16
Relationship: Fellow lawyer in community
"Jim Castle is without a doubt the finest attorney I have ever known. He has the most fantastic combination of incredibly high intellect, court room skill, creativity, legal knowledge and writing capacity, persuasiveness (with juries, judges and prosecutors). In addition to all of that, he has an unmatched work ethic and preparedness that is driven by a belief in defending his client with every option allowed by the Constitution. Criminal Defense is not a job for him, it is his passion. If you or a loved one are accused of a crime, you quite simply will not find a better attorney than Jim Castle."
