Expert guidance through a complex employment dispute

John Prendergast provided excellent counsel during a sensitive non-compete and trade secret dispute with a former executive. His deep knowledge of labor and employment law from the management side was immediately apparent, and his recognition in that field is well-deserved. He crafted a strategic approach that was both firm and pragmatic, leading to a favorable settlement without the need for protracted litigation. His advice on navigating the insurance implications was also invaluable. While his expertise is top-tier, communication could occasionally lag during very busy periods. Overall, I highly recommend John for any business facing complex employment or commercial litigation matters in the New Hampshire area.
