He is compassionate and honest. He immediately started to help my family from the first phone call. He responds urgently and was able to get my family the best resolution we could hope for with the least amount of added trauma.

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

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.
