Ron Denner


USC, MBA, Phi Beta Kappa, Army Infantry captain. Until recently owned the Ditch Witch dealerships for Colorado, Wyoming, Utah and Idaho.

Dumb lucky guy who has been blessed and is now chasing his last rainbow of having a world class winery and you can be the judge. Try the wines and tell us.

General Manager


Carol Rounsaville
General Manager

Carol spent 18 years working around fermentation before working for Denner. She started her management career at San Luis Sourdough, a local sourdough bread company. There she  discovered her passion – working for small, artisan-focused companies that create great food and wine. After a few acquisitions and a Crown Victoria as a company car, she  chose to leave the bread business and search out the small company environment again. After a few in-between positions, she found that perfect combination at  Denner.


Anthony Yount

As a kid Anthony always wanted to be a Cattle Rustler or a River Pirate. Unfortunately, neither of those professions were hiring when he graduated from Cal Poly. So Anthony “cut his teeth” in the wine industry here at Denner working as cellar rat for two vintages. Later, he moved up the road to become Cellar Master at Villa Creek, where he continued to work with Denner fruit. Coming full circle, Anthony returned to Denner as Winemaker in 2009. His winemaking philosophy is simple: “If you provide the grapes and wine with an environment where they can thrive and express themselves, they will do just that."


Aron Navarez
Vineyard Manager

Born in the village of El Durazno in Durango, Mexico,  Aron moved to Paso Robles in 1992 at age 14. As an early teen Aron worked in vineyards by “slightly” exaggerating his age.  By 1998, after working at Tablas Creek and Glenrose Vineyards, he took over management of the Rosette Vineyard (now Derby). Aron worked alongside John Alban for 6-years at Rosette before becoming manager at Denner Vineyards in 2004. Aron has developed the estate into a prized site for premium Rhone and Bordeaux varieties. He and his wife Yaraceth enjoy life in Paso Robles with their sons Aron Jr. and Jared.

Dave Mills  
Tasting Room Manager
Following a forty-year career in agriculture, Dave settled along the shores of his beloved Lake Nacimiento. He then started a second career in the tasting room here at Denner in 2014. His amazing attitude and commitment to the experience of our guests made him a perfect choice for tasting room manager – a role he assumed in 2016. “I was so fortunate to land here. It’s an incredible environment. The people, the wine… fabulous!” When Dave isn’t on the water, he enjoys the occasional round of golf, watching Cubs baseball, and entertaining with friends.


Jesus Sarmiento
Cellar Master
Jesus was born and raised in Oaxaca, Mexico and then later moved to Mexico City where he worked in the construction industry for 12 years before coming to the United States in 2006. There wasn’t much construction work available at the time so Jesus took a job at Stacked Stone Cellar where he worked in the winery and helped take care of the vineyard for almost 6 years. In 2012 he joined our vineyard crew here at Denner and had the chance to spend time in the cellar during harvest. His hard work and attention to detail made him an indispensable part of our team so we asked him to join the production crew in 2015. 


Theresa Wasley
Events Coordinator

Theresa designs and executes all events here at Denner Vineyards. When she’s not hosting at Denner she designs flowers for weddings and parties “I love what I do! Who wouldn’t like to throw parties for a living?” With a calm, don’t get stressed attitude, she finds joy in almost any challenge. Her favorite saying is “If you fall, pick something up, keeps people wondering if you planned it!"
