Value to Clients

"Legal problems do not happen in a vacuum, and neither should the advice clients receive. The best technical legal solution is not always the best solution for the client. When working with clients, I take the time to understand their business so that the advice I provide factors in the reality of their business operations and priorities."

Outside the Office

The stamina Sean developed as an endurance athlete helps him keep up with his three children. As an active family, Sean and his wife enjoy spending time outdoors and watching their children enjoy opportunities and experiences they didn't have growing up.
