I just wanted to thank you for your leadership. You have helped limit the scope to something manageable and therefore we have been able to accomplish more than we did when we were spread way too thin….
K.S., Non-profit Board Member
I recently read your Forbes piece on Tom Gearing’s Cult Wine Investment, along with your most recent interview with James Miles of Liv-Ex. I learned a lot about the fine wine market and technology so thank you!….

I loved your presentation in LOOKING AHEAD and hope that more wineries think about what they need to do to be successful and then act upon it.

I wanted to reach out and tell you what an absolute honor it was to see you on the panel of our virtual tasting. By listening to you taste and talk about the wine that I now work with on a daily basis, it reassured me in more ways than one that I truly am on the right path for my career within the wine industry. Thank you for your time and for being a constant and positive influence in what I do.

Thank you for an amazing past two semesters Professor! I really enjoyed both of your classes from the Intro to Wine Business to Senior Strategy Seminar this Spring. You’re my favorite teacher that I’ve had at Sonoma State by far! You really do a great job at teaching and care about your students and it shows.

We are wine consulting company from Mendoza, Argentina and I found your American Wine Consumer Report. It was really nice to discover your set of reports. I believe it’s very useful for wine exporters. Thank you very much!
RO, Argentina Wine Consultant
I am a sommelier from NY and based in Italy doing research on a new business ‘model’ to facilitate selling wine in foreign markets for smaller producers, focusing on US as initial ‘foreign market’. As I started this journey earlier this year, I’ve read your book on Wine Sales and Marketing and have come across numerous articles/surveys which you have authored and co-authored. Your research have been invaluable, especially to confirm data points/trends in the industry.
SD, Sommelier
