Will Maiberger has been involved in 30+ trials during his legal career as either “first-chair” or “second-chair” counsel for his various clients, which include seriously injured people, and families who have lost one or more loved one(s) due to the negligence of another person and/or company. During the first eight years of his legal career, Will worked as civil defense trial lawyer, defending wrongful death and personal injury cases, and insurance “bad faith” cases. Gaining this experience on the defense side provided him with a unique insight of how defense counsel, their clients and insurance carriers think regarding pre-trial and trial strategy, and case evaluation.

He is the partner in charge of the firm's Texas Prompt Pay Program. He is spearheading the prosecution of statutory causes of action for penalties, attorneys fees, and costs for thousands of medical providers across Texas. The firm's clients range from family-owned pharmacies to physician groups and large hospitals with hundreds of beds. Will travels statewide to meet with prospective and existing clients, and to attend mediations and arbitration hearings, while handling the day-to-day work associated with the proceedings related to their disputes with large health insurance companies.

Having worked on the firm's prompt pay docket for over four years, Will has established a rapport with medical providers. This is largely in part due to the firm working to ensure that medical providers' practices are disrupted as seldomly as possible, leavnig the doctors, practice managers, administrators, and pharmacists able to run their businesses without interruption.

Will has given speeches on mass tort litigation and the multi-district litigation (MDL) process, product liability issues and the mechanics of the Texas Rules of Civil Procedure. He has also been active in his local trial bar, serving as an officer and director of the San Antonio Trial Lawyers Association since becoming a plaintiffs’ trial lawyer in 2001.

In addition to the demands of a trial lawyer’s practice, Will spends quality time with his wife and children. His daughter, Roxanna, is an honor student and member of the marching band at The University of Texas.
