ISBT Member Since: 1998
What I Love About ISBT: For me, this organization has been a great experience. When I started attending the ISBT, many of the board members reached out to me to get me engaged into the technical committees. One board member, Tom Leitch, told me that I will get out what I put into it and he was right. The strength of our organization is our people and how our members work together to develop guidelines and practices that help improve the industry. I have learned a great deal and developed many friendships. Joining the board, becoming part of the Executive Board, serving as President, has help me both personally and professional. It has given me a much better understanding of the beverage industry. I am excited about our new ISBT Institute program. This program will help both our new and old members gain important knowledge that they can take back to their jobs and further show the industry that we are the premier beverage organization. As a former president, I look forward in helping our membership and giving back as Tom did to me.

What I Love About ISBT: Our Society is made of individuals who generously share their time, expertise and contributions with their peers, strengthening their organizations' leadership position while advancing their skills and careers. It levels the playing field by offering individuals and companies in less advantageous position, a unique and safe space for technical collaboration and professional development.

What I Love About ISBT: I first joined ISBT in 1997. Since then it has been a source of knowledge, a source of inspiration, a place to make friends, and a place to develop business networks and contacts for me.

Every year after BevTech, I mark my calendar for the next BevTech and start counting the days until I get to see the friends and colleagues I've known for many years, the new friends and colleagues I've met in the current year, and the future friends and colleagues I'll meet at the next BevTech.
