Collin County Criminal Defense Practice Areas
Focused, disciplined representation for a limited number of clients — because a criminal charge deserves preparation, not processing.
O’Toole Law, PLLC is a Collin County criminal defense attorney representing clients across McKinney, Plano, Frisco, Allen, and the surrounding communities. Founded by Jon O’Toole, who has practiced criminal defense in North Texas since 2013, the firm was built on a simple principle: fewer cases, handled with more discipline, produce better outcomes than volume ever will. Rather than moving clients through a standard process, O’Toole Law limits its caseload so that every client’s charges, history, and goals shape a strategy built specifically for them. That approach demands more preparation and more direct communication — but for someone facing a criminal charge in Collin County, it’s the difference between being managed and being represented. Getting this type of representation protects clients’ freedoms and their careers when criminal charges affect their professional licenses too. Schedule a consultation to talk through your case and what a deliberate defense looks like.
O’Toole Law, PLLC handles criminal cases throughout Collin and Denton counties, including McKinney, Plano, Frisco, Allen, Denton, Lewisville, and Little Elm. The firm also accepts cases in Grayson, Fannin, Hunt, and Tarrant counties. Professional license defense matters are handled statewide
