Press Releases


I suffered serious personal injuries after a drunk driver ran a red light and collided into the driver’s side of my car at a high rate of speed. I didn’t know Bill previously, who was referred to me by an old family friend, but I consider myself lucky to have landed in his good hands. From day one, Bill was the consummate advocate. He kept me informed, explained my options step-by-step, and was available anytime I had any questions. His tenacity resulted in a significant settlement from both the drunk driver and the bar that had served the driver. I had a great experience with Bill and everyone else at Gallagher & Kennedy and would highly recommend Bill and his firm.

William (Bill) King represented my wife and me after a rollover accident in which we were not at fault. Initially, because we were fortunate to walk away with only minor injuries, we had not planned on engaging an attorney. However, after quickly realizing how complex of a situation we were facing and how unprepared we were, Bill offered to help, and I am sure glad we took it.

Bill is wicked smart and experienced in his practice, yet he took the time to walk us through the process and gather our opinion before acting. Bill handled our case swiftly and professionally, always keeping us informed. He also informed us of benefits we were entitled to through our own insurance company that we never knew we had.

I would highly recommend Bill (or G&K, for that matter) in the unfortunate event you need legal representation after an accident. Thank you, Bill!

We didn’t know Shannon or Bill before we were referred to them by a family friend shortly after our serious auto accident. Shannon and Bill were patient in explaining our options and making sure we knew important details before making key choices. They were extremely professional and knowledgeable through every step of the process. We really felt like we had experts and advocates on our side. They got us a great result.
