Criminal Defense

Our team has developed a wealth of skills and experience through many years of service, and numerous victories for previous clients. Each attorney is fully dedicated and passionate about their practice, and this means you can rest assured knowing they have your back in such an important matter. We have worked with clients who have been charged with a wide variety of different allegations, ranging from small misdemeanor criminal charges to serious federal felony charges.

Our criminal lawyers could be able to help with your case if it relates to any of the following:

DUI Defense

We fully comprehend the life-altering effects of a DUI conviction. A successful conviction can lead to hefty fines, license suspension, and even imprisonment. If you’ve been apprehended and are facing criminal charges, we can assist you in defending yourself against DUI allegations.

Once you have obtained legal representation from one of our team, we can begin providing you with legal counsel and can help you build the most robust defense strategy possible. We can represent you in court, negotiate with prosecutors and fight for the best possible outcome on your behalf.

If you are charged, we will do everything in our power to reduce the impact on your life, such as helping you pursue the reinstatement of your license if it has been suspended or revoked.

Drug Crimes

Drug crimes are punished fairly severely in our state, so if you are facing criminal charges for a drug-related crime, we recommend that you contact an Oklahoma City criminal defense lawyer from our law firm immediately.

A drug crime conviction can have long-lasting implications on both your personal and professional life, and may affect your chances of employment in the future, your chances of applying for a mortgage, and may hamper your ability to seek custody or visitation rights of your children.

The key to fighting drug crimes is building a malleable strategy for our clients, exploring every avenue possible. If we can’t fight the charges, we will work hard to have the sentencing reduced. This is where the relationships we have built with some of the prosecutors of the state can prove invaluable.


Often, new clients and old clients alike come to us to ask about expungement.

If you have a criminal record, you may be entitled to have your record expunged, removing it from public record. This means that the only people who can see your record are law enforcement and certain legal entities.

This means you may not have to disclose your record to potential lenders or employers, reducing the impact that your criminal record will have on your life.

If you have been wrongly accused or have committed certain non-violent felonies or misdemeanors (excluding those crimes that require you to be on the sex offender registry), expungement may be an option for you.

To determine if you are eligible to have your previous charges expunged, contact us today for a complimentary consultation with our Oklahoma criminal defense attorneys to discuss your criminal defense requirements, and we’ll work with you to build a better future.

Federal Crimes

If you’re charged with a federal crime, the consequences can be harsh, including a prolonged prison sentence, substantial financial penalties, and a criminal record that could adversely affect your personal and professional life.

Our team is here to help you fight against these charges by providing you with the best possible legal defense. We will strive to get your charges dismissed, but if that’s not possible, we’ll be there to assist you with sentencing guidelines, appeals, and post-conviction relief issues.

Military Defense

At our firm, we’ve assisted numerous clients in navigating the complexities of court-martial, administrative proceedings, and discharge upgrade requests across all branches of the military. We have a wealth of experience in working with the Army, Navy, Air Force, and Marine Corps.

In addition, our team is well-equipped to provide servicemembers with guidance on security clearances, military retirements, and veterans’ benefits, among other related issues. We understand the unique challenges faced by military personnel and are committed to providing tailored solutions that address their specific needs.

Child Custody

When divorcing spouses have children, there is an added level of complexity.

Oklahoma City, OK Family Law Attorney – FAQ

How is child custody determined in Oklahoma?

Child custody in Oklahoma is determined based on the best interests of the child. This means the court considers certain factors, such as the child’s emotional ties to each parent, the ability of each parent to provide for the child’s needs, the physical and mental health of each parent, and any history of domestic abuse or neglect. The court may also consider the child’s preference, but this does not dictate the decision.

There should be no bias because of a parent’s gender. Both father and mother should be treated equally entering into a custody battle.

Can child custody arrangements be modified in Oklahoma?

Yes, child custody arrangements can be modified in Oklahoma if a material change in circumstances affects the child’s well-being. However, it is not an easy task.

Examples of material changes in circumstances include a change in one parent’s living situation, a change in the child’s school or extracurricular activities, or a change in the child’s health.

To modify a custody arrangement, the parent seeking the modification must file a petition with the court and show that the modification is in the child’s best interests. This is why it is important to discuss any potential modifications with a skilled attorney.
