Denver Personal Injury Lawyer

Personal Injury, Car, Motorcycle, Truck Accidents

 As a managing partner at Keating Wagner Polidori Free, I concentrate my practice on catastrophic personal injury cases in Denver and throughout Colorado. I am deeply aware of the guidance and support my clients need when navigating complex legal issues in personal injury cases so that they can focus on healing. I work tirelessly for my clients, whether it’s in the courtroom or in a settlement conference, to get the very best outcome possible.

While working with Keating Wagner throughout law school I developed a love of the courtroom. Most importantly, as a plaintiff attorney, I learned the importance of understanding my clients and the severity and long-term effects of their personal injuries by getting to know my clients, their families, and their medical team. Telling each client’s individual story of loss with the finest in technology, medical evidence, and expert testimony, is my single focus for each and every case. I have extensive experience in wrongful death cases, trucking cases, product defect cases, traumatic brain injuries, pharmacy errors, and prosecuting child sexual abuse civil cases, as well as other personal injury cases. I have a proven track record of winning great settlements and large personal injury verdicts, even when going up against large insurance companies.

I am proud to be recognized by my peers and colleagues as one of the top accident trial lawyers in our state. My care and commitment to my clients is evidenced by my results. One of my greatest achievements is being among the list of attorneys who won two of the largest plaintiff personal injury jury verdicts in the Colorado in 2013.

Experience in Auto Wrecks, Wrongful Death and Catastrophic Accidents

I pride myself on setting a tone of unwavering standards for my clients, including transparent communication. I never make a significant legal decision without first getting my client’s approval. There is never a one-size-fits-all approach because all of my cases are unique and include highway accidents, motorcycle injuries, house explosions, and fires. My client’s specific needs always come first. Whether a client’s personal injury damages are economic (lost wages or medical expenses), or emotional (turmoil such as chronic physical pain, or loss of enjoyment in life), I fight aggressively for justice and compensation in my accident and injury cases.

Proven Results in Serious Colorado Auto Accident Cases

I began my legal career with a focus on civil litigation in both Colorado state and federal Courts. I am a member of the Colorado Bar, American Bar, Denver Bar, and American Association for Justice. I have successfully obtained fair compensation for a myriad of cases, including the wrongful death of a man caused by failure of a tire seller to warn of a dangerous tire, wrongful death of a child caused by negligent life-guarding, wrongful death of a young man caused by a hazardous property condition, serious orthopedic injuries caused by a car accident, serious physical injury caused by a pharmacy error, and a traumatic brain injury caused by the negligent operation of a tractor-trailer.

In each of these cases, my goal was to help my clients and their families get back on their feet after the incident. My structured and detail-oriented approach allows the families of those involved in a wrongful death suit to focus on each other – not their legal case. It is my top priority to be a personal injury lawyer that normal everyday people can trust. My goal is to secure the best-case resolution that allows victims and their families to get back to their lives.

Consumer Product Injuries

The Consumer Product Safety Commission suggests that each year in our country, consumer products injure 31 million Americans and kill an additional 23,000 (Source). Rightly so, dangerous products lead to plaintiff product liability cases and lawsuits.  To secure top results, my product liability cases have an essential chain of command aspect which requires that measures be taken promptly. Dangerous and defective product evidence must be preserved, and the chain of custody documented with the utmost care for expert witnesses such as engineers or doctors to thoroughly evaluate the product and our client’s injuries. Having the seasoned knowledge and accomplished experience to hold a manufacturer, wholesaler, or retailer of a product liable is a focus for an attorney like myself who has the insight and familiarity of the personal injury aspects of product liability law.

Additional Background Information

It is unique to our firm to have a female managing partner as many Colorado personal injury firms are not led by women attorneys. I joined Keating Wagner in 2007 after working with the firm as a legal assistant. . My family and I  enjoy living in Colorado and believe our community is one of the best in the country.
