About Glenn E. Gaskill
Glenn E. Gaskill III is a Wisconsin-licensed attorney who has built a practice around criminal and traffic defense work. He operates out of Grieve Law, LLC and has moved between small firm practice and solo practice during his career. His path shows steady involvement in cases that often hinge on police procedure and courtroom tactics.
He began his formal training in political science at the University of Wisconsin–Eau Claire, completing a Bachelor of Arts in 2003. He later earned a Juris Doctor from Marquette University Law School in 2010. Those academic years framed an interest in trial advocacy and the intersection of law enforcement practice and individual rights.
Gaskill’s early post-law school role was as managing lawyer at Eric S. Brittain, LLC beginning in 2010. He took on responsibilities that included supervising case preparation and courtroom work. Three years later he launched his own practice under his name, signaling a move toward more direct client contact and solo representation.
In 2017 he joined Grieve Law, LLC as a lawyer, continuing work on criminal defense and traffic-related matters. That move brought him back into a small firm setting where he could pair his courtroom experience with collaborative case handling. Over the years his résumé reflects steady courtroom activity rather than administrative or large firm specialization.
Gaskill has pursued training that aligns with the practical needs of DUI and traffic defense. He completed the National Highway Traffic Safety Administration and International Association of Chiefs of Police Standardized Field Sobriety Testing student course under the 2018 curriculum through Platt and Associates. He also completed the corresponding instructor course under the same curriculum. He has taken a course on cross-examining police officers in DUI cases offered by Your DUI Pro. Those programs inform both the defense strategies he employs and the questions he frames when challenging officer testimony.
Colleagues and clients see him as a practitioner who returns often to the nuts and bolts of evidence and testimony. He has handled matters that require careful parsing of police reports, video evidence and procedural compliance. His courtroom approach is direct: he prepares to test testimony and highlight procedural gaps when they appear. His current practice centers on DUI defense and related traffic matters.
