Expert guidance through a complex non-compete dispute

I engaged Lauren Irwin at Upton & Hatfield after my former employer threatened legal action over a non-compete agreement when I started a new role at a competing firm in the Portsmouth area. The situation was incredibly stressful, but Lauren's deep knowledge of New Hampshire employment law was immediately apparent. With over three decades of experience, she expertly dissected the overly broad language in my original contract and formulated a strategic defense. Her recognition as a 'Lawyer of the Year' in Employment Law was well-earned; she navigated the nuances of the case with a calm, authoritative presence that gave me great confidence. Lauren and her team prepared meticulously, and we achieved a very favorable settlement without the need for protracted litigation, which was my primary goal. While her expertise is top-tier, there were occasional delays in receiving email responses, likely due to her demanding caseload. However, when we did connect, her attention was complete and her advice was invaluable. For anyone in the Seacoast region facing employment-related legal challenges, particularly in management or individual disputes, Lauren S. Irwin is a formidable and highly skilled advocate.
