Why Choose The Goolsby Law Firm?

Mike Goolsby spent the early years of his career prosecuting DWI and felony cases for the Dallas County District Attorney. Since 1999, he has been on the other side of the courtroom defending them. That former-prosecutor background is the firm's primary value — Goolsby knows which assistant DAs will go to trial, which will negotiate, and what the office's internal valuation of a case looks like. The firm is solo-led; you work directly with Mike Goolsby. Best fit for first-offense DWI, repeat DWI, drug possession, and assault cases where you want a hands-on defender who knows Dallas County prosecutors.

What Clients Say

Client
Robert M.
DWI 1st · Dallas County
★★★★★
Got pulled over leaving Uptown. Blew a 0.09. Goolsby filed for the breath-test calibration records, found a maintenance gap, and the DA dismissed. I got the case expunged. Couldn't ask for more.
Client
Sarah B.
Assault Allegation · Plano
★★★★★
Domestic assault charge from a chaotic situation. Mike investigated, got the alleged victim's statement walked back, and the case was dropped. He treats the case like it matters because for me it did.
Client
Tom W.
Drug Possession · North Dallas
★★★★★
Cocaine possession charge with no clean way out. Goolsby got me into pretrial diversion. Did the program, case dismissed, no record. Knew which DA to talk to.

FAQ

Common Questions About This Firm

Should I take the breathalyzer in Texas?
Refusing a breath test in Texas triggers an automatic 180-day license suspension under the implied consent law. Taking it and failing is also bad evidence at trial. Most criminal defense attorneys, including Goolsby, advise refusing the breath test for first DWI stops where you're not visibly impaired — but every situation is different. Always request to call your attorney.
What is an ALR hearing?
Administrative License Revocation. After a DWI arrest, Texas DPS sends notice they will suspend your license. You have 15 days to request an ALR hearing or you lose the right to one. The firm files the ALR request as part of every DWI engagement.
How does pretrial diversion work in Dallas County?
Pretrial diversion is a program for first-offense, low-level cases where the DA agrees to dismiss the charges if the defendant completes counseling, community service, and other conditions. Successful completion means no conviction. Goolsby has a strong record getting clients into diversion.
Will Mike Goolsby personally handle my case?
Yes. The firm is solo-led. Mike Goolsby personally meets with every client, attends every substantive hearing, and tries every case the firm litigates. Support staff handles intake and scheduling.
How much does a DWI cost in total?
Beyond attorney fees, plan for: $3,000+ in court costs, fines, and fees if convicted; $1,000–$2,500/year increase in auto insurance; $125–$2,000 surcharges (now repealed for some classes); ignition interlock costs; and program fees. The total cost of a Texas DWI conviction often exceeds $15,000–$20,000.
