A Full Service Criminal Law Firm

A Respected Professional


Watch Your StepMr. Carroll is well respected by court staff in state court, federal courthouses, as well as by other criminal defense attorneys in Houston. Though inside the loop, he thinks outside the box & isn’t afraid to stick his neck out for a client. He learned early on that anyone working to be the best criminal defense attorney in Houston had to be ready to go to trial & not be mindlessly bound by convention, or precedent.

Many of his case dismissals are a result of taking cases to trial court in Harris County. Prosecutors spend most of their time at the courthouse and know the “thems that do & the thems that don’t.” Court settings in Harris County are often adversarial, and if the prosecutor makes a plea bargain that’s turned down by the client, two alternatives remain: change your “Not Guilty” plea to BEG, or set the case for trial.

If the lawyer is not a trial attorney by nature, blessed with a well-known reputation, the criminal defendant may be treated poorly.

A Few Reviews By Former Clients

  • for the accidental death of a Harris County Sheriff’s Deputy. My family isn’t rich and thought my brother would be discriminated against. Regardless, me and my family pulled together and hired the best attorney our money could buy. I remember my brother telling me that when Mr. Carroll personally surrendered him to the Harris county jail, the room was full with HPD and Harris County Sheriff Deputies.

    The Deputy my brother was accused of murdering worked there. Mr. Carroll told the crowded room if Mr. Ibarra is messed with there will be hell to pay.When I visited Ricky and was told this I thought Ricky might have a chance, I know guts when I see or hear about them – I was a Special Forces Marine Sniper in Iraq and Afghanistan. My brother got his own cell and was treated well. Ricky’s case was dismissed during jury deliberation and he walked, unassisted out of court at the end of the trial. Other than major depression about the Deputy he’s doing well with a wife, kids, and a great job. HO AHH

    When I honorably discharged from the Marines I didn’t know what to do with myself and ended up getting busted by the DEA for Manufacture, Delivery, or Intent to Deliver a Controlled Substance, mainly 255 grams of cocaine and was enhanced because I was carrying a firearm.

    Get an affirmative finding for carrying a firearm while selling drugs and you can kiss parole goodbye. Jack set the case for trial and had a suppression hearing. My partner got 20 years with a deadly weapon finding, I got deferred adjudication. My case has since been dismissed and there will be no public record of it after Jack files a motion for Non-Disclosure. HO AHH

An Experienced Criminal Defense Attorney

Houston criminal defense attorney Jack B. Carroll has learned by hard-earned experience that criminal offense reports don’t always tell the truth, the whole truth & nothing but the truth. Nor do they tell the whole story, and he never forgets the presumption of innocence.

If a defendant asserts their innocence, they’ll be treated as such regardless of Carroll’s personal opinion.

Attorney Jack B. CarrollJack isn’t too busy or self-important to return a phone call & doesn’t resent calls from clients or their families. He doesn’t cheat, nickel & dime his clients or pawn them off to other lawyers either. Also, Mr. Carroll has never been disciplined for professional misconduct by the Texas Bar, nor any bar association.

Even if a client is guilty as charged, Jack keeps in mind they may not be the same person tomorrow as they were on the day they were charged. However, criminal charges & criminal records never change unless sealed, expunged or hidden from the Houston public record.

Jack will take a case to term if the situation calls for it. In his arsenal are a host of retired Houston law enforcement professionals & other resources to draw from when it comes to defending clients.
