Interesting Insights:

When I was introduced to Certain I realized from my BI experience the exciting opportunity that event data could mean for marketing and sales. Data from events is a rich source of buyer behavioral predictions and I knew from my enterprise sales experience that face to face meetings at events are a powerful way to propel sales cycles. The opportunity to leverage events to drive sales and marketing was irresistible.

I’m on a never ending journey to learn to play jazz piano and create music through improvisation. My three kids play guitar and our interest in jazz and blues keeps our relationship in tune (pun intended). We moved to the Bay Area twenty years ago but family (including two of my kids) in Boston keep us close to our lobster and chowder roots!
