Personal Injury

We represent people who have been injured by another person’s negligence or unreasonable behavior. When this happens, the effects can be catastrophic both physically and economically. If you’re in this situation, you need an experienced, aggressive attorney who can take a stand on your behalf against the corporations and insurance companies involved. Let us be your voice.

Worker’s Compensation

Worker’s Compensation is an insurance benefit available to nearly all employees who suffer an injury in the course of their employment. Laws are designed to ensure that employees injured on the job receive fixed monetary awards, making Worker’s Compensation an important safety net for many people. Do not get taken advantage of by your employer or its insurance company. We know how to collect your maximum benefit and can guide you through this difficult time.

Criminal Defense

We have experience in all aspects of criminal defense. No case is outside our realm of expertise. In fact, Attorney Grant G. Alvine is a former prosecutor with dozens of trials. Attorney Zachary T. Flood has defended clients in capital cases and murder trials and everything in between. Our entire team will work to protect your rights, which are guaranteed by our Constitution. We will fight for you.


Litigation attorneys are critical if you are looking to file a legal claim or defend against one.

From construction and business disputes to estate and trust representation. Click below to learn more.
