William J. Ronalter bio photo

Bill Ronalter is chair of Shipman's Catastrophic Injury Practice Group. Bill represents individuals who have sustained substantial personal injuries and wrongful death cases. In the legal world, everyone wants results, and Bill’s results speak for themselves, but what sets him apart is that, at Shipman, he focuses on the quality of his representation of clients in catastrophic injury cases, rather than the quantity of injury cases he is involved in at any given time. This focus allows him the flexibility to be responsive and to listen mindfully to his clients and their needs.  Bill prides himself on communicating regularly and proactively with his clients as developments warrant.

Bill has more than 30 years of experience handling personal injury cases in various roles, including plaintiff’s lawyer, defense lawyer, and as a consultant for an insurance company. He managed cases throughout the country involving catastrophic injuries including death, paralysis, traumatic brain injuries, amputations, Legionnaires' disease, and burns. Bill has experience in the following types of cases: airplane crashes, accidents involving motor vehicles, motorcycles, bicycles, and pedestrians (including DUI cases), uninsured and underinsured motorist claims, products liability (including defective lithium ion batteries in laptops, I-Phones, and E-cigarettes that caused burn injuries), premises liability, construction accidents, drowning, dental and medical malpractice, nursing home negligence, and sexual abuse. He represented 8 of the 10 passengers that were injured or killed in the B-17 crash at Bradley International Airport in 2019 where he reached a confidential settlement.  He has served as an expert witness and testified regarding proper claim handling practices. Bill has also served as a guest lecturer (2009-2012) and an adjunct professor (2013-2023) at the University of Connecticut School of Law, Trial Practice Class.  Bill Ronalter and Jim Bergenn often use videos to assist with case resolutions.

Experience

Aviation crashes

Settlements Reached in Crash of B-17 Bomber at Bradley International Airport

After mediation before retired Judge Robert Holzberg of Pullman & Comley LLC, The Collings Foundation, Debra A. Riddell, Craig A. Rubner, Scott Rubner, Joseph M. Roberts, Joseph Huber, Jenny Huber, Thomas Schmidt, Linda Schmidt, and Joan Mazzone announce the resolution of all claims arising out of the tragic crash of the B-17 known as Nine-O-Nine at Bradley International Airport on October 2, 2019. While it is our sincere hope that this resolution brings peace and closure to those affected, The Collings Foundation deeply regrets the injuries and losses suffered by the passengers and their families that day. Shipman lawyers Bill Ronalter and Mark Ostrowski represented eight of the ten victims of the crash.

Dental malpractice

$900,000 SETTLEMENT – Dental Malpractice – Nerve Injury Caused When Dentist Used Too Much Pressure During Root Canal With Calcium Hydroxide

Our client, a 61-year-old woman, had a root canal performed by her dentist, who she had treated with for decades.  We claimed that the dentist used too much pressure while applying the calcium hydroxide during the root canal procedure.   As a result, the calcium hydroxide went beyond the apex of the tooth and into the mandibular canal.  The dentist referred her to an oral surgeon, who performed surgery to remove as much of the calcium hydroxide from the mandibular canal as possible.   However, our client still suffered from permanent symptoms including pain, numbness, and that she had difficulty with chewing certain foods.   At the first mediation shortly before litigation was filed, the insurance carrier only offered $150,000, but after a year and a half of litigation, depositions of all the parties, and several months before the start of trial, the case settled for $900,000 at a second mediation.

Bill worked with a medical illustrator to create a
demonstrative aid that was used at the mediation and would have been used at trial to show the broken instrument inside our client.

Wrongful death

$2,150,000 SETTLEMENT -- Passenger killed in one car crash

We represented the estate of a 19 year old man, who was a passenger in a car when the vehicle traveled off the roadway striking a utility pole killing our client.  We recovered all available insurance ($1,850,000) and an additional $300,000 contribution paid by the owner of the car for a total recovery of $2,150,000.

$1,650,000 SETTLEMENT – Defective Product –  Death of a 58 year old man

We represented the estate of a 58 year-old single man with no children for a wrongful death claim against the assembler of a commercial truck.  Our client was found dead entangled in a PTO shaft underneath his parked truck with a screwdriver in his hand while he was making a delivery for his employer.  There were no witnesses to this tragedy.  Our mechanical engineering expert opined that the truck was defectively assembled because: (1) it should have included a guard around the PTO shaft; (2) the pump in the truck was facing in the wrong direction requiring any repairs on the pump to be made while under the truck rather than along side it; and (3) the truck lacked any warnings about the dangers of going underneath the truck and near the spinning PTO shaft.  Defendant denied that the truck was defective and instead blamed our client for going underneath the truck and putting himself in harms way.  We had an economist that concluded the loss of earnings to the estate was between $282,000 and $397,000.   After more than 10 depositions were taken of first responders, our client’s employer, the parties and our experts, the case settled following a mediation several weeks before trial was scheduled to begin.


* Please note that prior results do not guarantee a similar outcome in other matters or cases, as each case has a unique set of facts and circumstances.

General

$36,500,000 ARBITRATION AWARD - Defective Product - Catastrophic Burns to 3 Year Old Boy and 33 Year Old Father

Our clients, a 3-year-old boy and his 33-year-old father, suffered third degree burns to over 70% and 50% of their bodies respectively and we argued that a lithium ion battery exploded from an electronic device. We brought claims against the product assembler, distributor, and seller. After three unsuccessful mediations and more than 50 depositions, the claims were presented to an arbitration panel. The result of the arbitration was a gross recovery of $36,500,000 for our clients.

$5,025,850 SETTLEMENT & ARBITRATION - Defective Product - Catastrophic Burns

Our client, a 63 year old man, suffered third degree burns to 40% of his body when a defective product exploded during a social event.  We brought claims against the product manufacturers, a large national retailer, and a third party consumer who used the product.  After preparing a multi-media presentation, the claims against the various defendants were settled following an arbitration and mediation for a combined amount of $5,025,850.

$5,000,000 SETTLEMENT - Truck Strikes Cyclist - Leg Amputation

We represented the employee of a longstanding corporate client, who was sideswiped by a truck when he was riding his bicycle home from work. Initially, the truck driver told the cops our client was on his phone, no witnesses to the crash were identified, and we did not know if our comatose client would live and/or remember how the crash occurred. We got our client’s phone records (through his employer) and proved he wasn’t on his phone. Our accident reconstruction expert inspected the scene and the evidence, and we taught the detective the specific state statutes that protect cyclists. We requested the 911 dispatch tapes and learned that there were witnesses to the aftermath of the crash that called 911 reporting that the truck driver was attempting to leave the scene. We later learned that the truck driver lied to the cops and used another name at the scene of the crash because he was in the United States illegally. Unfortunately, due to the extent of the injury to his left leg, our client had his leg amputated above the knee approximately a month after the crash. We gave the insurance carrier an opportunity to settle the case as we drafted the Complaint to commence the lawsuit explaining that if they did not offer their $5,000,000 limits, we expected a verdict over the coverage when the case was tried. The carrier responded by offering its $5,000,000 policy limits available for this loss, which will give the client financial security as he starts the next chapter of his life.

$4,500,000 VERDICT - Dental Malpractice - Overfill of Sealer During Root Canal

Through a referral from an in-house attorney from one of our corporate clients, we represented an executive in a dental malpractice case.  Our client was injured during a root canal where the dentist over instrumented leading to a large over fill of sealer some of which went into our client’s mandibular canal.  The defendants disputed liability, causation, and damages.  The defendants’ insurance company offered only $200,000 two weeks before trial.  After three weeks of evidence, including the use of technology at trial, Bill Ronalter obtained a verdict of $4,500,000, which consisted of $165,000 for past and future medical bills and $4,335,000 for additional harms, including constant pain, fatigue from prescription medications, and the reduction of enjoyment in many aspects of her life.  In addition, we filed an Offer of Compromise agreeing to settle for $750,000 the year before the trial.  Since the verdict was in excess of $750,000, interest runs from when the litigation started in February 2013 bringing the total amount to up over $5,300,000.  This verdict is the largest dental malpractice verdict in Connecticut history and is believed to be the largest dental malpractice verdict ever nationally.
