It’s all about our clients. Clients want a successful firm, but they also want to know that we care.


Josh represents the third generation of Koskoffs at Koskoff Koskoff & Bieder. Known for his dedication, compassion, and creativity, Josh brings a fresh and unique perspective to all his cases. Like his father and grandfather, Josh believes strongly in the role of the lawyer as a fighter whose sole purpose is to improve his clients’ lives through the legal system. He views the law as working only when it works for all people and not just the powerful. His personal concern for the welfare of each of his clients has won their trust and devotion. 

 Josh has won substantial, record-setting medical malpractice and other verdicts throughout Connecticut and has also taken on powerful interests in cases with national implications. He recently achieved a historic settlement for 9 families of victims of the 2012 Sandy Hook Elementary School shooting in a landmark case against the Remington Arms Company: the manufacturer and marketer of the assault rifle used to carry out the attack. The settlement of $73 million was the entire amount of insurance available from the bankrupt company, and to date is the only settlement won against a gun manufacturer for a mass shooting in American History. A major component of the settlement was the right to release internal corporate documents obtained during the lawsuit to the public. 

 Josh also represented Sandy Hook families against controversial "conspiracy theorist" Alex Jones for his false claims that the Sandy Hook shooting was staged and that the families were actors. Last year, Josh and partners Chris Mattei and Alinor Sterling obtained a verdict in the case totaling almost $1.5 billion - the largest verdict in Connecticut history, and the largest defamation verdict in American history.  

 In 2019, Josh filed another groundbreaking lawsuit against Harvard University on behalf of the Connecticut descendant of an enslaved father and daughter who were abused as part of a “scientific study” conducted by a racist Harvard scientist in 1850. Josh won another landmark legal decision when the Massachusetts Supreme Judicial Court recognized for the first time that institutions have a legal duty to treat descendants of enslaved and indigenous people with respect and dignity. He also currently represents 80 women against Yale University in a sprawling drug diversion case that has attracted national attention and spawned the hit podcast series “The Retrievals” by Serial.  

 Regardless of whether it’s a case of national importance, or it involves helping one family cope with catastrophic or life changing loss, Josh feels most rewarded fighting for his clients to try to help them have better and more satisfying lives.
