Jennifer O’Connell

Managing Partner and Owner of our Colorado Office, Jennifer O’Connell has practiced in civil litigation for fifteen years in complex premises, auto, cycling, motorcycle, and tractor-trailer collision cases. Jennifer brings Queener Law’s hometown feel of a family-style firm and their nationwide experience to the mountains.

Experience Matters…

Jennifer hails from the Great Smoky Mountains of Knoxville, Tennessee. After attending Appalachian School of Law and the University of Tennessee College of Law, Jennifer practiced personal injury for nearly a decade across the state of Tennessee. In her practice, Jennifer handled cases involving premises liability, auto collisions, pedestrian and bicycle crashes, and tractor-trailer collisions. Jennifer also developed a department focusing on mass torts and pharmaceutical class action cases. Since moving to Colorado, Jennifer has continued to build on her experience and expertise in these areas. She offers consulting services in the fields of C.R.C.P. Rule 30(b)(6) depositions, discovery, and witness preparation for testimony and she lectures across the Denver Metro area and on Trial Guides in those fields.

… So Does a Winning Record.

Jennifer is licensed to practice in Colorado and Tennessee, including four federal courts. She has tried cases in three states and has practiced in over thirty-five counties. Jennifer has also argued before the Court of Appeals. While in Tennessee, she commonly took more cases to trial than any other attorney in her field and won record-breaking verdicts. Her team has kept it up in Colorado to ensure that their clients receive their full and fair recoveries. They have already achieved millions of dollars in jury trials in Colorado – collecting verdicts against corporations like Starbucks, HOAs, and apartment complexes – and will continue to take their deserving clients to the courthouses across the country.

In 2020, after only three years in Colorado, Jennifer was named Law Week’s Barristers Best Civil Litigator in the State of Colorado and the New Trial Lawyer of the Year by the Colorado Trial Lawyers Association. She has continued to collect honors every single year since. Jennifer has also provided research and brief contributions for a 7 to 2 Decision before the United States Supreme Court.

Jennifer has been published on LexisNexis and has litigated against pharmaceutical corporations, national and international commercial carriers and trucking companies, some of the largest corporations in the U.S., and insurance carriers like Progressive, Travelers, GEICO, State Farm, Farmers, American Family, Nationwide, Liberty Mutual, USAA, Hartford, Cincinnati Insurance, Allstate, Esurance, Permanent General, SafeCo, Zurich, Chubb, Bristol West, and many more. She has also negotiated with health insurance companies like Medicare, Cigna, Aetna, Medicaid, Kiser, United Healthcare, Anthem, and BlueCross BlueShield to keep money out of the pockets of the insurance companies and in the pockets of her clients. Jennifer has also been published on TrialGuides for Preparing Expert Witnesses for Deposition and Trial, Preparing Lay Witnesses for Deposition and Trial, and Increasing Case Value Through Discovery Disputes.

Outside the office, Jennifer checks off countries on her travel list, hikes, skis, and snowshoes in the Back Country, and cycles around Denver. She serves as the Vice President of the Board for the Rescue for PTSD. In her capacity as Vice President, she helps train dogs who have been rescued from shelters or unhealthy and unsafe environments and give them to Veterans as fully-trained service dogs – free of charge. When you pass her on the hiking trail, make sure you stop to pet her many family pups or one of her foster service dogs in training!
