Trustindex verifies that the original source of the review is Google. What I admire most is how Charles treats his clients. I have heard stories about people who can’t even get their lawyers to return their calls. Charles truly cares about his clients and makes every person he represents feel like their case matters as much to him as it does to them. He’s honest, exceptional in the courtroom, and the first person I tell people to call if they need a Georgia criminal defense attorney

Trustindex verifies that the original source of the review is Google. Charles at Cullen Law is truly an exceptional attorney and one of the most dedicated professionals I have ever had the privilege of working with. One of the best criminal defense attorneys in Georgia. From the very beginning, he demonstrated a level of professionalism, knowledge, and commitment that immediately put my family at ease. What sets Charles apart is not only his legal skill but also the genuine care he shows for his clients. He is incredibly communicative, easy to talk to, understanding, and compassionate. No matter the day or time, he was always available when we needed him, even on weekends. Knowing that he was only a phone call away gave us tremendous peace of mind during one of the most difficult periods of our lives. Charles took on a case that was extremely complex and challenging, one that many attorneys would not have been able or willing to handle. He worked tirelessly, left no stone unturned, and fought for us every step of the way. When it came time to argue our case, it was clear that he had invested an extraordinary amount of time, preparation, and effort. His dedication and attention to detail were unmatched. Charles is the person you want standing by your side. Most importantly, Charles delivered an outstanding outcome for my family. I can honestly say that he helped change our lives for the better. Throughout the entire process, he made us feel protected, safe, and supported. We never felt like just another case; we felt like people he genuinely cared about beyond his professional obligations. Charles saved my family's life. Even after our case was resolved with a big win, Charles has continued to be there for us whenever we have questions or need guidance. That level of commitment is rare and speaks volumes about his character and integrity. If I ever need legal representation and criminal defense again in Georgia, there is no question who I will call. Cullen Law is the only law firm I would trust to stand by my side and advocate for me. I cannot recommend Charles highly enough. If you need an attorney who is intelligent, hardworking, compassionate, professional, and relentless in fighting for his clients, Charles is the person you want in your corner.

Trustindex verifies that the original source of the review is Google. There are not enough words to express our gratitude for Criminal Defense Attorney, Charles Cullen, and everything he did for our family. When our son was falsely accused of a serious crime, we found ourselves facing the most terrifying and stressful time of our lives. His future, reputation, and freedom were all at stake, as he was facing the possibility of a 20-year prison sentence for a crime he did not commit. From our very first conversation with Charles, we felt a sense of relief. His calm demeanor, confidence, knowledge, and genuine concern immediately reassured us that we had found the right attorney. Hiring Charles was one of the best decisions we have ever made. Quite simply, he helped save our son's life and future. Charles possesses an extraordinary combination of intelligence, intuition, legal knowledge, and strategic thinking. His extensive trial experience and exceptional courtroom skills were evident throughout every stage of the case. He thoroughly analyzed every detail, developed a powerful defense strategy, and fought relentlessly on our son's behalf. The outcome Charles achieved exceeded what we thought was possible. What began as a case carrying a potential 20-year prison sentence was ultimately resolved with probation. We will forever be grateful for the dedication, skill, and determination he brought to our son's defense. What also sets Charles apart is the way he treats his clients. He is incredibly responsive, whether day or night, always making himself available to answer questions and address concerns. He listens carefully, never rushes conversations, and never makes you feel like just another case. We always felt that our family and our son's future truly mattered to him. If your freedom, your future, or the future of someone you love is on the line, you want Charles Cullen standing beside you. He is an outstanding criminal defense attorney, a fierce advocate, and a true professional. We recommend him without hesitation and will remain forever thankful for what he did for our family. Sandy and Bob B.

Representing Autistic Clients

Police encounters, interrogations, and courtroom appearances can go wrong fast — not because of guilt, but because of how autism affects communication, stress responses, and interaction with authority. Eye contact avoidance, flat affect, literal interpretation of questions, or freezing under pressure can all be misread as deception, defiance, or
indifference.

At Cullen Law, we proudly represent people on the autism spectrum — and the families who support them — in criminal matters throughout Georgia. We understand how ASD shapes the facts of a case, and we build defenses accordingly.

What to Do If You Are Arrested

Your criminal defense case begins the moment you encounter the police. You do not have to answer their questions or even identify yourself unless the police detain you. You can ask the police at any time if you are free to go, and if they say no, you are being detained.

If you are detained, you must identify yourself, but you are not obliged to answer other questions—and you should not. Instead, tell the police you choose to remain silent and ask for a lawyer.

If the police arrest you, maintain silence and ask again for a lawyer. Call an Alpharetta defense attorney at your first opportunity and wait for him to arrive before you answer any questions.

If You Are Stopped in a Vehicle

When you are stopped while driving, you must present your license, registration, and insurance information on request. You do not need to consent to a search.
If the officers suspect you are driving under the influence of alcohol or drugs, they may arrest you on suspicion of DUI. Once arrested, you may be asked to provide a urine or blood sample for testing. Under O.C.G.A. § 40-5-55, a refusal to consent to testing can be used to suspend your driver’s license for one year. Additionally, your refusal may be used against you in a DUI prosecution.

Why You Should Work With a Criminal Defense Attorney

Working with a skilled lawyer in Alpharetta could make a huge difference in the outcome of your criminal case, even if you think the odds are stacked against you.

We independently review the circumstances surrounding the investigation and arrest to determine whether the police violated your rights—if so, it may be possible to dismiss the charges or at least suppress evidence they obtained illegally. In every criminal case, we investigate every viable defense. Such defenses include:

Alibi
Improper collection or handling of evidence
Insufficient evidence
Lack of intent
Mistaken identity
Self-defense
Unreliable witness

Entrapment, duress, and other defenses might be applicable in certain cases.

Every situation is unique, and at Cullen Law, we individually tailor your defense to offer the best chances of a favorable result in your specific case.

Speak With an Alpharetta Attorney If You Face Criminal Charges

Having an experienced Alpharetta criminal defense attorney can make the difference between dismissed charges and a life-altering criminal conviction. Whether you are accused of DUI, a misdemeanor, a white-collar crime, or a complex felony, Cullen Law can help. The sooner you reach out to us, the sooner we can get to work on your case.
