Attorney Mark A. Hammer founded our firm with the belief that all individuals charged with a criminal offense deserve to have genuine support throughout the entirety of their case. At The Hammer Law Firm, LLC, we make it our mission to ensure that our clients always have access to our St. Louis criminal defense attorneys when they are in need. As we have proven our ability to be there for our clients during the darkest of times and throughout each step of their legal process, you can be confident that, should you decide to work with our firm, caring legal minds will be by your side.

Here for You Every Step of the Way

Attorneys Mark Hammer and Nicole Chiravollatti are truly accessible. When you call our firm, you don't get passed off to secretaries, paralegals or voicemails, you get your lawyers. In fact, our attorneys go one step beyond this by providing each of our clients with our direct cell phone information. When you have questions, call us. When you have concerns, call us. When new evidence comes to light or when you wish to discuss something about your case, we will always be there to answer your questions. We consider the services we provide equivalent to doctors who make house calls - we are, in some sense, handling your life and future, and we are always very careful and aware of this responsibility.

Our passion for supporting our clients is not some marketing scheme or superficial tactic we employ, it reflects who we are and what we believe in. We believe that, regardless of the circumstances, clients come to attorneys in times of need, times of fear, and times of uncertainty. Being arrested and charged with a criminal offense is a deeply frightening experience, and we know that when you are unfamiliar with the legal system and what to expect, these fears can be exacerbated immensely. As such, we know that it would simply be wrong for clients to not know about the progress of their case or to not speak with the person they hired to do the job.

While we believe that open, honest, and constant communication is key to supporting our clients through tough times. We also know that communication plays a vital role in their case. Keeping you involved and listening to what you have to say aids our legal team when constructing your defense and navigating your case. For these two reasons alone, there is no reason why your lawyer should deliver anything but the constant support and contact you rightfully deserve and require.

Experience our commitment for yourself. Contact us today!

At The Hammer Law Firm, LLC, we practice what we preach and we stand tall by the notion that actions speak louder than words. As such, we encourage you to experience our earnest commitment for yourself by allowing our lawyers to provide you with a free case evaluation. This is your opportunity to find the support you deserve and the representation you need. Contact a St. Louis criminal defense attorney from our firm today.
