Jon E. Rosenstengel is a seasoned personal injury attorney who dedicates his complete practice to litigation on behalf of those who’ve been harmed by the negligence of others and those who’ve been harmed on the job. In other words, Jon’s focus is on your personal rights – rather than on the financial interests of the powerful insurance company that’s handling your personal injury claim.

Mr. Rosenstengel has decades of experience helping claimants like you obtain the compensation to which they are entitled and that they need to regain their health and well-being. Additionally, he will leave no stone unturned in his quest to achieve your claim’s optimal outcome.

Practice Areas

Mr. Rosenstengel’s practice focuses on the following areas:

  • Workers’ compensation claims that address injuries sustained on the job and include construction accident claims
  • Traffic accident claims, including truck accident claims
  • Personal injury claims generally

If you were injured in the course of your work or by someone else’s negligence, Mr. Rosenstengel is on your side and has the experience, resources, and drive to help skillfully guide your claim toward a favorable resolution that supports your legal rights and affords you rightful compensation.

Background and Experience

Mr. Rosenstengel was admitted to the Illinois Bar in 1993 and to the Missouri Bar in 1994, and he has a unique combination of both professional and personal experience that informs the skilled legal guidance he provides. He is also licensed to practice in Northern Central and Southern Districts in federal court in Illinois as well as the Eastern District of Missouri in Federal Court.

Before becoming an attorney, Mr. Rosenstengel worked as a private investigator for a law firm, and the skills he obtained in this capacity inform the important investigative work he does for his personal injury clients. This unique background leaves Jon well-positioned to effectively and efficiently advocate for advantageous claim outcomes that uphold his clients’ rights and best interests.

The Private Investigator Difference

Before Jon Rosenstengel joined Bonifield & Rosenstengel, P.C., he followed in Mr. Bonifield’s footsteps by pursuing experience as a private investigator. The skills he honed as a PI translate well to the investigating he does as a personal injury attorney, and his clients benefit immensely from the unique perspective his background offers.

Investigation plays a critical role in successful personal injury claims, and the difference that experience in private investigations can make includes all the following:

  • The ability and finesse to obtain meaningful witness statements from bystanders and eyewitnesses who may otherwise be reluctant to share
  • The skill and insight to capture photographic evidence that is difficult to refute
  • The ability to gain a holistic view of accident scenes, which serves to flesh out personal injury and workers’ compensation claims

The advantages associated with PI experience in relation to personal injury law are difficult to overstate.
