Lawyers & Staff




Areas of Practice

  • Medical Malpractice
  • Personal Injury

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 the 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 verdicts throughout Connecticut, and has taken on powerful interests in cases with national implications.  He currently represents 10 families of victims of the 2012 Sandy Hook Elementary School shooting in a landmark case against the Remington Arms Company – the manufacturer of the assault rifle used to carry out the attack.  He also represents Sandy Hook families in a suit against the controversial “conspiracy theorist” Alex Jones for his false claims that the Sandy Hook shooting was a “hoax” and that it was staged by actors.  Recently Josh filed suit against eight manufacturers of assault weapons on behalf of the family of a victim of the Las Vegas shooting – the deadliest mass shooting in American history. 

In March, 2019, Josh filed another groundbreaking lawsuit against a powerful defendant – Harvard University -- on behalf of the Connecticut descendant of an enslaved man named Renty and his enslaved daughter named Delhia.

Regardless of the nature of the case, Josh feels most rewarded fighting for his clients, and knowing he has helped his clients to have better and more satisfying lives.
