Let’s Collaborate!

I welcome any opportunities to help others discover more about wine! My wine club and tastings aren’t the only ways I can serve you! If you need a personal sommelier for your next event or if you’d like to have a wine expert on your podcast or maybe you want to feature a sommelier’s opinion on pairings in your next article… whatever the case may be, I’m just an email away from helping you fall in love with wine just a little bit more!
