Major life transitions such as leaving the protected environment of school or starting a new career can be daunting. It is scary to face a wall of choices, knowing that no one is going to tell us whether or not we are making the right decision. There is no clearly delineated path or recipe for success.

That is, until now.rnrnAs executive director of the Stanford Technology Ventures Program, Tina Seelig guides her students as they make the difficult transition from the academic environment to the professional world, providing tangible skills and insights that will last a lifetime.
