Vineyard and Estate

John Calmeyer, General Manager

Douglas Lumgair, Estate General Manager: Almost 25 years ago Doug laid the infrastructure that keeps the Estate functioning to this day. From the day Mr Stein pruchased the property, Doug's vision for Windsor Oaks was key in getting everything started and today he is the essential element that keeps it all running. In his time off he enjoys hiking on the estate and flying his plane with his true love, Julie Hagler Lumgair. 

Ralph Hoag, Manager of Grape and Bulk Wine Sales: Ralph Hoag, Manager of Grape and Bulk Wine Sales: Ralph was determined to learn the wine industry from the ground up by schooling and working in the vineyards and cellars of California’s North Coast. Based on his skill, integrity and dedication, Ralph stepped into his current role after being hired as an intern in 2011. Quiet and hardworking while in the office, he'll happily talk grapes and wine with you any time.
Guadalupe Ruiz, Vineyard Foreman Guadalupe Ruiz, Vineyard Foreman:  After living on the Estate and working in the vineyards for over 30 years, Lupe knows this place better than anyone. Season by season he guides his crew in the cultivation of some of the County’s highest quality grapes. He leads by example and there’s no one we’ve seen who can match his speed, efficiency and precision in the vineyard. Lupe lives on the property with his wife and several cats. 
Armando Alvarez, Estate Construction and Maintenance Foreman Armando Alvarez, Estate Construction and Maintenance Foreman: Throw anything at Armando and he’ll tackle it head on. You can’t keep this guy down. Always joking as he gets the job done, Armando keeps a low profile, but this place couldn’t function without him. From equipment maintenance to general Estate improvements, he does it all. 




Tom Schmidt, Enologist Tom Schmidt, Enologist: A Sonoma County native, Tom’s been immersed in the wine industry since birth. Growing up on his family’s vineyard, enology was a natural course to follow. But he didn’t limit himself to what he could learn here; Tom has worked in New Zealand and Australia, as well as with Malbec in Argentina. And, if you ever have a chance, give his home brew a try. You won’t be disappointed.  
Antonio Garcia, Cellar Hand Antonio Garcia, Cellar Master: Windsor Oaks is a bit of a family business for Antonio. Both his father and uncle have worked in the vineyards here, but he was the first to step into the cellar. A new father himself, Antonio looks a bit bleary-eyed these days, though he’s as hard a worker as ever, and knows his way around a winery better than most. 


Lynn Bond, Hospitality Coordinator

Lynn Bond, Hospitality Coordinator: Always ready with a genuine smile, kind word and inventive idea, Lynn makes Windsor Oaks a special place for anyone lucky enough to run into her. Having worked the majority of her life in the hospitality industry, welcoming people is Lynn’s gift.  In addition to her passion for food and wine, she also loves photography, graphic design and restoration.

Trish Moyer, Bookkeeper

Trish Moyer, Bookkeeper: From some seriously complicated accounting to coordinating wholesale orders, Trish stays very busy. Lucky for everyone, though, she’s very organized and does a great job staying on top of it all. A proud mother, Trish knows her biggest accomplishment is raising her sons Josh and Ryan to be the wonderful, kind and amazing young men that they are.
