I have been teaching for the International Sommelier Guild for nearly two decades and have had the opportunity to teach all over the world at many levels. 

While so many cultures differ, the love for food, family, wine, and the gathering together of friends binds them all together. I love exploring new cuisines and discovering both classic and modern wine pairings for them, yet one of my greatest joys is watching the success of his former students. 

The process of turning someone’s passion for wine into a dedicated practice and skillset is incredibly rewarding.

Teaching for ISG is the having the complete pack. I get to look at wine, beer, sake, spirits and liquors not only as beverages, but as an indelible part of human history. In the least, it is culture. At best, it is nourishment for the soul.
