Olsman MacKenzie Peacock

What Olsman MacKenzie Peacock does

Olsman MacKenzie Peacock is a privately held Michigan personal injury law firm founded in 1969 and headquartered in Berkley, with additional offices in Lapeer and Battle Creek. The firm represents injured individuals on a contingency-fee basis across practice areas including motor vehicle accidents, medical malpractice, nursing home abuse and neglect, premises liability, wrongful death, birth injuries, and product liability. Approximately 90% of new clients arrive via referrals from other attorneys, signaling a peer-reputation-driven acquisition model, and the firm holds a U.S. News and World Report First-Tier ranking in Medical Malpractice Law for Plaintiffs.

The firm is staffed by 8 attorneys and 4 in-house registered nurses — a structurally unusual configuration for a plaintiff-side PI firm. The nurses (Nancy Studer, Jackie Liu, Alissa Kowalski, Nicole Poney) conduct medical record review, identify standard-of-care deviations, and support courtroom presentation, providing a clinical edge in med mal and nursing home matters. Named partners include founder Jules B. Olsman (Michigan Super Lawyers since 2007), President Donna M. MacKenzie (Super Lawyers Top 50 Women and Top 100 since 2014), and Emily Peacock (Chair of the AAJ Women Trial Lawyers Caucus for 2025–2026).

The business model is purely outcome-based: clients pay no attorney fees unless the firm recovers damages, with free initial consultations as the primary lead-conversion mechanism. Disclosed case results include an $8,000,000 cancer misdiagnosis settlement, a $4,750,000 child abuse wrongful death settlement, a $4,400,000 medication-error jury verdict, and a $4,350,000 dram-shop settlement, with the firm claiming "hundreds of millions of dollars" in cumulative recoveries. The firm uses no proprietary technology platform or AI tooling; operations are conducted as a traditional personal injury practice with marketing via website, blog, client testimonials, and a toll-free intake line.
