Hernández & Associates, P.C.

We Understand What You Are Going Through
At Hernández & Associates, P.C., our attorneys are here to help. We have attorneys with decades of experience fighting and negotiating fair deals and trying cases in both state and federal courts in Colorado. Because we limit our practice to the areas of criminal defense and immigration law, we can devote every resource to helping our clients whose most important legal rights are on the line.
One of the things that makes our criminal defense firm different is that we gather as much detail as possible to consider all the different outcomes in your case. If you take a plea bargain deal, for example, that can impact your immigration status. Our attorneys consider these outcomes and give this kind of careful attention to every case.
Unlike many firms, we regularly take cases to full trial, meaning our attorneys have significant experience fighting for our clients before judges and juries. Preparing each case for trial also means we carefully evaluate every possible way to reduce the charges our clients face — or have them dismissed altogether.
Contact us today if you need legal assistance with any of the following:
- Criminal Defense
- DUI
- Immigration Law
