Joshua Patrick GrubeJoshua is an aggressive trial lawyer with extensive trial experience.  As an 11 year veteran State Prosecutor, Joshua has tried over 100 cases to a Judge or Jury.  From disorderly conduct and drunk driving cases to felony drug delivery and child sexual assault, Joshua routinely convinced juries to side with him. Joshua now concentrates his practice to litigation and focuses on criminal defense and civil cases.


Joshua has spent his career in the courtroom.  Joshua has cultivated very positive working relationships with Circuit Court Judges, State Prosecutors and law enforcement officials.  Joshua has a very close working relationship with law enforcement and worked closely for years with the Walworth County Drug Enforcement Unit.


Joshua is also a teacher and a trainer.  Joshua taught police officers around the State legal updates and best practices to help ensure officers were properly trained to handle their cases legally and ethically.


Joshua has extensive experience working with children and families.  To better help those who have been victims of abuse and neglect, Joshua has been specially trained in how children disclose abuse and in how children behave during and after abuse. Joshua has trained professionals around the State on the best practices in investigating these sensitive cases.  This specialized training and experience makes Joshua uniquely qualified to handle these complex issues.


Joshua firmly believes that your best defense in any criminal matter is a good offense. Good people routinely find themselves in serious legal trouble.  Joshua understands that each client has an important history and story to tell that goes far beyond what can be learned from a police report.  Joshua has had great success in influencing prosecutors' charging decisions, and getting criminal charges reduced or dismissed, by sharing with prosecutors “the rest of the story.”   Joshua prepares every one of his cases as if it were to be tried to a jury.  This shows prosecutors that he knows his case and is ready to put the State to their burden.  It is this philosophy that so often results in very favorable outcomes for his clients.   His experience as a longtime prosecutor allows him to analyze a criminal case from both sides to develop and deliver thoughtful and effective defense strategies.


By really listening to his clients, understanding their needs and goals, and by truly caring about their unique situations, Joshua is able to achieve remarkable results.
