Apple Class Action Case: $25,000,000 Settlement

September 2023 - Ms. Harper served as Plaintiffs' marketing, advertising, and promotion expert witness.

I very strongly recommend Ms. Harper from Harper Litigation Consulting and Research. She is great to work with and her work product is absolutely top-shelf. Partner, Greenberg & Traurig

I would characterize Ms. Harper's courtroom testimony as one of the best I’ve seen in doing this 34 years. Very well prepared, unwavering in the face of cross-examination, and very persuasive to the jury. Very well done. Partner, Matthews, Lawson, McCutcheon & Joseph
