Nigel Cartwright

Wine Club Concierge

A native son of Birmingham, England, Nigel brought his love of wine (and Queen Elizabeth) across the pond to settle in the Napa Valley. You might recognize him from his six years in the Markham Tasting Room, where his fanbase of regulars grew to love both his excellent rapport with visitors and his deep knowledge of Markham wines. In his new role with the Wine Club, Nigel enjoys building personal relationships with Markham members. Not a member yet? Check out club information here.

Winemaking & Vineyards

Kimberlee Nicholls


“It’s so invigorating to be in Napa Valley or at this beautiful winery. When it smells like harvest, you can smell the grapes, it’s alive and it’s fantastic. It’s a fantastic job.”

Kim is a chemist full of energy and life, with a long history in Napa and a deep love of Merlot. As one of the first female winemakers in the Napa Valley, she is highly respected in the area. With three decades of experience under her belt, we are thrilled and humbled to have her on our team. Her food-friendly winemaking style is fueled by a love of cooking and the connective ritual of pairing lovingly prepared food with artfully made wines. Kim is an integral part of Markham’s story and has greatly contributed to our countless accolades and enduring place as one of Napa Valley’s great wineries.

Robert Diaz

Cellar Master

Robert’s passion manifests in a serious tone peppered with infectious laughter. He prefers to let his work speak for him and his incredible dedication is clear in his immaculate cellar and intricate understanding of cellar techniques and style choice. His refined palate, can-do attitude and innovative thinking add immense value to our winemaking team.

Patricia Sciacca


A Napa Valley native, Patricia grew up on Atlas Peak high in the Vaca Mountain range that forms Napa Valley’s eastern edge. She earned her degree from Cal Poly SLO, where she developed a fascination with the effects of chemistry on the sensory aspects of wine. When not immersed in the cellar or lab, she enjoys spending time outdoors, hiking or fishing with her husband … or relaxing with a glass of wine alongside her tiny grey kitten Murphy and not-so-tiny rottweiler Magnum.

Abigail Horstman

Assistant Winemaker

An avid traveler, Abigail has worked harvests from Napa to Italy to Israel. She first joined the Markham cellar in 2017 as an enologist, and returned to the winery in 2021 to become our Assistant Winemaker. Her favorite thing about winemaking at Markham is the innovation and willingness to try new things and, of course, how food-friendly the wines are.

Adrienne Uboldi

Vineyard & Sustainability Manager

“The most rewarding part of what I do is being able to see the full growing season from pruning to bud break through harvest.”

Adrienne is a lover of nature, science and soil so it’s no surprise she spends her days furthering the sustainability efforts in our estate vineyards. A self-proclaimed outdoorsy nerd, she walks the vineyards listening to podcasts and studying spreadsheets of the latest soil results. Her sustainability-centered vineyard management approach is invaluable to the health of our employees, land and fruit.

Behind the Scenes

Kate Mcmanus

VP of Marketing

Kate loves her people as much as her P&Ls and has a passion for vineyard views and sunsets over the Mayacamas. With a quarter century experience under her belt in the wine business, this Gen X’er believes that life is better lived with a glass of wine in your hand, preferably a glass of Markham, surrounded by cherished friends and family.

Kim Moore

Marketing Director

Kim is our wine temptress, connecting great wines with great people. A family boat in her youth named ‘Chardonnay’ may or may not have influenced her career path but her love of wine and food — most specifically cheese — have kept her engaged. With creativity and enthusiasm, she invites you to fall in love with the world of Markham.
