Mackenzie J. Mahony

Mac Mahony is a trial lawyer who has dedicated his career to representing victims and their families in cases of serious personal injury and wrongful death. Mac has helped secure multiple record-setting financial recoveries for his clients both at trial and through settlement. Mac is licensed to practice law in Illinois and Wisconsin and concentrates his legal practice in areas including wrongful death, catastrophic injury, motor vehicle collisions, medical malpractice, and nursing home abuse and neglect.

Mac is a talented trial attorney. Recently, Mac secured a jury verdict of over $1.4 million dollars for a woman who was riding her bicycle and was struck by the opening door of a parked car. The jury award was an excess verdict against the Defendant’s insurance company who refused to accept responsibility, refused to offer the $100,000 policy limits, and ultimately resulted in an award for his client of over eight times the policy limits.

The legal community has also recognized Mac’s accomplishments. Mac is a Super Lawyers Rising Star (2020-2023), a distinction reserved for only the top 2.5% of attorneys in the state. He is also an Emerging Lawyer (2020-2023), recognizing him as one of the top 2% of young lawyers who has proven himself at an early point in his career. These honors reflect Mac’s legal skills, hard work, and devotion to his clients.

Mac’s other recent successes include a $1.25 million dollar settlement for a man who was injured in a disputed liability collision; a $4.275 million dollar medical negligence settlement at trial for a man who had a left lower leg amputation; a $1 million dollar settlement for a man who fell from a negligently poured concrete staircase; and a $900,000 settlement for a Wisconsin car accident in which the family recovered $550,000 for conscious pain and suffering above Wisconsin’s $350,000 cap on wrongful death damages.

Prior to joining Taxman, Pollock, Murray, & Bekkerman, LLC, Mac practiced medical malpractice and nursing home litigation at prominent Plaintiff and Defense firms in Chicago. Mac prosecuted and defended acute and long-term care facilities in personal injury litigation across Illinois. He has tried, and won, jury trials both on behalf of victims and their families and care providers. Mac’s experience prosecuting and defending nursing homes and hospitals has provided him with invaluable perspective, which he employs to maximize recovery for his clients.

Mac is also active within his community. He currently serves on the Associate Board for Guest House, a nonprofit organization, which provides temporary housing for patients and their families while receiving medical treatment in Chicago.


Some examples of Mr. Mahony’s noteworthy results include:

  • $5,350,000.00 settlement on behalf of a 45-year-old man who was a passenger in a golf cart rollover incident in Galena, Illinois, due to a steep and unsafe cart path, which caused multiple and permanent leg injuries.
  • $4,275,000 medical negligence settlement at trial for a man who had a left lower leg amputation.
  • $2,550,000 settlement on behalf of a 2-year-old girl who sustained bilateral second and third-degree burns to her hands due to an allegedly defective appliance at a home in Shorewood, IL. The injuries required multiple surgeries and a two-week stay in a burn unit.
  • $1,750,000 medical negligence settlement on behalf of a 58-year-old man whose physician allegedly failed to diagnose his prostate cancer, which became metastatic and terminal.
  • $1,482,000.00 jury verdict for a mom on her bicycle and who was hit by a car door and sustained pelvic and dental injuries.
  • $1,250,000 settlement for a man injured during a disputed liability collision.
  • $1,027,500 settlement on behalf of the Estate of a 72-year-old man who was injured, and later died, after falling from the front concrete steps at the home of an acquaintance.
  • $1,000,000 settlement on behalf of the estate of a pedestrian who was struck and killed by an automobile. Plaintiff was standing near the curb in front of his home in Elk Grove Village when the Defendant made an improper left turn causing the driver’s side mirror to strike Plaintiff in the back of the head. Plaintiff was clearing leaves from a storm drain on the corner by his home at the time. He sustained a closed head injury and died the following day. He was survived by four grown children.
  • $1,000,000 settlement on behalf of the estate of a group home resident who was left unsupervised in the home’s kitchen where he accessed solid food, which was inconsistent with his diet. The resident choked and, ultimately, died from complications of asphyxia.
  • $1,000,000 settlement on behalf of a group home resident who required assistance with activities of daily living, medication management, and demonstrated poor safety awareness. During a summertime outdoor activity at the facility, the Plaintiff suffered from heatstroke resulting in complications including sepsis and an extended ICU stay. We alleged that the Plaintiff was taking four medications that increased the likelihood of him becoming overheated or dehydrated and, as such, were contraindications for extended sun exposure.
  • $950,000 settlement for the estate of a resident who died from post-operative complications after falling at the defendant nursing home.
  • $900,000 settlement of a Wisconsin lawsuit on behalf of the Estate of a 56 year old man who was the victim of a fatal head-on collision after the Defendant driver attempted an illegal pass in a no-passing zone.  The Defendant driver only had a $25,000 insurance policy and Wisconsin law capped the wrongful death damages at $350,000.  We argued not only that the Defendant driver was delivering auto parts for the benefit of a third-party retailer, but also that the decedent experienced seconds of conscious pain and suffering both in anticipation of and following impact.
  • $800,000 record settlement (Logan County, IL) on behalf of a nursing home resident who developed a pressure sore to her sacrum, requiring treatment, including multiple debridements.
