Case summary from Stuart R. Day | Attorney at Law
Williams, Porter, Day, & Neville, P.C.
Phone 307.265.0700

Dale Hallerberg, P.E. with Active Alliance was retained by a medical device design/manufacturer/sales company named as a defendant in a Federal court action as an expert witness to assist in the defense of the medical device design/manufacturer/sales company. The plaintiff in that action alleged the medical devise design/manufacturer/sales company product caused a physical injury to him during operation.

Mr. Hallerberg conducted in-person testing of the product and came to the conclusion that the plaintiff’s allegation of how the devise performed during the alleged event was not possible. Hallerberg also participated in the preparation for deposing plaintiff’s expert witness. The Federal court ultimately entered summary judgment in favor of the medical device design/manufacturer/sales company finding its product was not defective.

Recommendation from Mr. Kevin B. Tucek, Co-Owner, Chief Engineer

Mr. Hallerberg labored diligently to ensure that any scenario plaintiff could present was addressed, tested and documented; in order to prepare an expert witness report with integrity. Our defending attorney stated that in his 20 plus years of practice, he had not seen a better more complete report. In our case, the judge concurred.

We would be willing to use Dale Hallerberg again for any service that called for expert knowledge of Electro-Mechanical devices, particularly medical devices and the ISO, UL, and FDA codes that regulate them, and believe Mr. Hallerberg would be an asset to other conpanies with the same needs.
