Representative Experience
For more than the past 30 years, Mike has been involved in the development of medical and scientific defenses and has participated in successful trials, Daubert hearings, and “Science Day” presentations to courts in many of the highest profile national “mass torts”/ mass claim litigations affecting United States and foreign manufacturers of FDA-approved prescription and over-the-counter drugs, vaccines, medical devices, cosmetics, and other consumer products in both state and federal courts. During closing argument in one recent high-profile trial, a co-defendant’s counsel told the jury that Mike “had a knack for coming up with the right questions” during cross-examination of opposing experts.
Mike’s representation of clients has included serving as national, regional, and trial counsel in cases alleging links between:

One of these verdicts in 2017 was listed on the Courtroom View Network’s “Top Ten Most Impressive Defense Verdicts” in the country. Mike was also lead counsel for this client in a successful Kemp (Daubert) hearing in New Jersey state court that led to the exclusion of talc plaintiffs’ general causation cancer experts and summary judgment for his client in the first bellwether trials in the New Jersey consolidated state court proceedings.
