A Denver Defense Attorney

with Empathy and Understanding

When the reality of being criminally charged sets in, it’s common to feel overwhelmed. Your feelings might swing from confusion and fear to despair and hopelessness — even anger toward those accusing you and frustration with a seemingly uncaring system.

Jacob E. Martinez understands this. He also understands that just because you are charged with a crime, it doesn’t mean you’re guilty of anything.  Further, even if you may have had a temporary lapse in judgment, it doesn’t mean you should be treated harshly, like a mere “criminal.”  There are many reasons one may face criminal charges, and each case is different.  Each client has their own story, background, and unique circumstances. Because of this, The Law Office of Jacob E. Martinez approaches criminal defense with compassion, support, and optimism.  We take the time to learn the unique reasons each client is facing criminal prosecution, and we work to provide light in what is often a very dark time — no matter the case, no matter the client.  We don’t believe criminal charges should define a person, and we work hard to provide the support and skill necessary to allow our clients to move forward in their individual lives so that they can reach their fullest potentials.
