Why Choose Sullo & Sullo?

Sullo & Sullo is what you get when a firm builds itself around volume without losing its edge. Andrew Sullo and his team have handled cases for more than half a million Houston-area residents since opening — personal injury, criminal defense, DWI, traffic tickets, immigration. That kind of bench gives them a feel for how prosecutors charge, how insurers settle, and how Harris County courtrooms move. They run Spanish-language operations alongside English, take contingency on injury cases (no fee unless you win), and quote flat rates on most criminal matters. If you want a firm that has seen your situation before — and probably yesterday — start here.

What Clients Say

Client
Maria R.
Car Accident · Southwest Houston
★★★★★
"Got rear-ended on the 59. Their team handled the insurance company so I could focus on physical therapy. Settled for more than I thought possible. Andrew explained everything in plain Spanish for my mom."
Client
DeShawn M.
DWI Defense · Harris County
★★★★★
"First-time DWI. Sullo's team got the breathalyzer thrown out and the case dismissed before trial. The flat fee was clear from day one — no surprises. Worth every penny."
Client
Jennifer L.
Truck Accident · West Houston
★★★★★
"Hit by an 18-wheeler on I-10. They subpoenaed the trucking company's logs and proved the driver was over hours. Six-figure settlement. Their paralegals called me every week."

FAQ

Common Questions About This Firm

Do I pay anything if Sullo & Sullo doesn't win my injury case?
No. Personal injury cases are taken on contingency, which means the firm only gets paid if they recover money for you. If there's no recovery, you owe no attorney's fees. The contingency percentage is disclosed in writing before you sign anything.
Do they handle Spanish-speaking clients?
Yes. Sullo & Sullo runs a full Spanish-language operation alongside English — intake staff, paralegals, and attorneys. You can call, sign documents, and review your case entirely in Spanish.
How fast can I speak to an attorney?
For injury cases and criminal arrests, intake is typically same-day. The firm takes calls 24/7 for urgent criminal matters and arranges in-office or video consultations within hours when needed.
What's the flat fee for a typical first-time DWI?
Flat fees vary by complexity, but a straightforward first-time misdemeanor DWI in Harris County is typically quoted in the $2,500–$5,000 range. Felony DWIs, repeat offenses, and cases going to jury trial cost more. You'll get a written quote before retention.
What areas around Houston do they serve?
Harris County (Houston, Pasadena, Baytown), Fort Bend County (Sugar Land, Missouri City), Montgomery County (The Woodlands, Conroe), Brazoria, Galveston, and Liberty Counties. Virtual consultations are offered statewide in Texas.
