Rob Frasca

Managing Partner

Rob Frasca

Passion is critical to success and therefore my first priority in everything I do is to create enduring passion. I do this with enthusiasm, drive but most of all solid, experienced LEADERSHIP. Passionate people constantly seek new challenges and opportunities to drive their performance to new levels. For passionate people, achieving their full potential has little meaning. They see that their potential is constantly being expanded by new possibilities.

Passion is about Pursuit. It is not passive. People with passion are driven to pursue and create. They may read books and observe others, but they are not content being bystanders. They feel an overwhelming urge to engage, to experience for themselves and to test their own capabilities. Passion compels us to act.

Passion leads us to seek out and connect with others sharing our passion. We intuitively understand that the best way for us to advance is to connect with and learn from others. I strive to “always connect the dots” in everything I do.
