I am a results-oriented, energetic advocate for my clients. I am passionate about representing my clients. As most cases come from word-of-mouth referrals, I am proud of my reputation built one client at a time. Most clients are faced with a difficult challenge in a critical part of their lives: their jobs and careers. I am competitive and look forward to taking the fight to the employer to redress unfair and illegal actions. I align our firm's fee arrangement with the client's desired outcome so that there is an identity of interest in the result sought. My success is defined by each client obtaining the desired outcome as a consequence of my effective counsel. Most of all, I love what I do, and that is helping people and seeking fair results for clients who deserve better treatment from their employers.
