The Personal Perspective
Hard work and dedication are the cornerstones of Sean’s practice. The proud son of a registered nurse and a mechanic who started and owns his own business, Sean’s work ethic was instilled at an early age and he has been regularly employed in various jobs since the age of 14. He graduated from college early, even though he worked contemporaneously for the university’s Athletics Department where he became the full-time Sports Information Director for the baseball program. He then put himself through law school to pursue his desire to work on labor and employment law matters. Today, Sean’s dedication to his work is mirrored only by that of his personal commitment towards those around him including his wife Emily, his daughter Hadley, and his close-knit group of family and friends.
