Colorado Criminal Defense Attorney
Arnulfo D. Hernández has dedicated his career to protecting the rights of others. For a decade, he has served his community through the legal representation of accused individuals. His law practice is broad and includes the defense of misdemeanors, felonies, and white-collar crimes. He is a courtroom attorney that regularly appears before Colorado state and federal judges. As he is a highly experienced criminal lawyer, Arnulfo D. Hernández provides defense strategies and tactics that other attorneys cannot. Through negotiation, persuasive argument, or jury trial, he always secures the best resolution possible for his client.

Colorado Immigration and Crimmigration
Arnulfo also protects the rights and liberties of others through immigration and crimmigration defense. Immigration law is a highly complex practice area that serves one of the most vulnerable populations in our country—those with immigrant or temporary status. Arnulfo D. Hernández has many years of experience guiding his clients through the sensitive, and sometimes lengthy process, of obtaining American citizenship. He regularly represents individuals in immigration proceedings before federal agencies including the U.S. Citizenship and Immigration Services, the Executive Office for Immigration Review, and the Board of Immigration Appeals. In situations where his client has been accused of a crime and faces immigration removal proceedings, a practice area known as “crimmigration,” Arnulfo has the hybrid knowledge to provide the most successful defense on all fronts.

Arnulfo D. Hernández is a leader in the Colorado legal community. He is the current President of Region XIII of the Hispanic National Bar Association (2017-Present) covering Colorado, Kansas, Nebraska, and Wyoming. He is also a past President of the Colorado Hispanic Bar Association (2016) and former Chair of the National Hispanic Bar Association's Immigration Committee (2014-2018). He stays active in volunteer activities sponsored locally by the Colorado Lawyers Committee and Metro Volunteer Lawyers. For its dedication to the community, Hernandez & Associates was presented with the Inclusiveness@Work award in the Law Firm category by the Center for Legal Inclusiveness in 2019.

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?

- How long has the lawyer been in practice? Has the lawyer worked on other cases similar to yours?

- How are the lawyer's fees structured - hourly or flat fee? Can the lawyer estimate the cost of your case?

- 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.
