Emanuele Gaiarin

Chief Executive Officer

Emanuele (Manu) Gaiarin’s top interests, apart from his family, are wine and sports, especially soccer. His interest in soccer started at birth and his interest in wine some time shortly after that.  He can say he’s been in the wine business since he was about six years old since he grew up in Italy surrounded by and learning from his twelve uncles and aunts-- all “winemakers,” toiling away on their craft in their garages and basements. When Manu was 14 years old, he was chosen for a first division farm team on the border with Switzerland. He moved onto playing professionally as a goalie for Portogruaro Summaga. Emanuele studied architecture at the University of Architecture in Venice for five years and completed his degree at the University of Minnesota. He kept his knowledge of wine current all these years while pursuing his other interests, luckily wine lends itself nicely to independent study and reflection. In 1996, Emanuele opened Siema Wines in the DC metropolitan area. Manu participates in the scouting and selection of a large portion of the portfolio and is in charge of the development of the European portfolio.

Sanford Dickerson

Sales & Product Director  / Sales - Northern VA / Washington DC

Sanford Dickerson’s interest in wine began right after college while working in a seafood restaurant in Seattle.  His knowledge expanded significantly in his mid 20’s as he and a friend took over a fine dining restaurant in west Michigan.  It was at this restaurant that the “aha” wine and food pairing moment occurred as Sandy and his partner paired a California Sauvignon Blanc with a goat cheese appetizer, at a time when “Chablis” and “Burgundy” were the wines of choice. After selling advertising for a couple of years, Sanford decided to combine his interest in wine and communication skills to sell wine.  He worked in the wine industry for 13 years before joining Siema Wines in 2004.

Garry Moore

Richmond - Charlottesville Area Manager

Garry Moore grew up in Portsmouth, Virginia. His first exposure to fine wine began early in his teens while working alongside his mom, one of the most highly regarded chefs in the Tidewater area. After attending Virginia Commonwealth University as a Political Science major, he started his professional wine career in the late 1970s with some of the most prominent restaurants in Tidewater and Richmond. His career has covered just about every aspect of the industry: sommelier, wine director/general manager for numerous high profile restaurants, retail wine buyer, wine educator and director of sales and marketing for a boutique Italian importer in the mid-Atlantic region. He has travelled extensively in the major wine regions of Europe and the United States over the last 35 years. Garry has been a sales consultant with Siema Wines for over 20 years.

Andrew Stover

Director of Sales & Marketing / Sales - Northern VA / Washington DC

Founder, Vino50: The Grape American Road Trip 

A native of Grand Rapids, Michigan, Stover dove into the hospitality and tourism fields after he graduated from George Washington University. Post-graduation he spent eight years at WHERE Magazine as an advertising consultant, familiarizing himself with the restaurant scene in the Nation’s Capital. Local Virginia vineyards, however, are where Stover found his true calling. Stover has traveled around the nation and across the glove to engulf himself in various cultures, cuisines and carafes. His travels have taken him to such great wine-producing areas as Argentina, Australia, Brazil, Chile, France, Germany, New Zealand, South Africa, Spain and even the UK. After holding a part-time job at the tasting room at Breaux Vineyards in Hillsboro, Virginia, Stover enrolled in the Certified Sommelier program with the International Sommelier Guild and landed at DC’s OYA Restaurant & Lounge as Wine Director. Stover’s overhaul of the wine menu at OYA gained him attention from not only DC area media, but the Wine industry as well. OYA has received the coveted Wine Spectator Award of Excellence and consecutive nominations for Wine and Beverage Program of the Year from the Restaurant Association of Metropolitan Washington. With a Sommelier Diploma from the International Sommelier Guild and a Certified Specialist of Wine certification from the Society of Wine Educators, Stover has taken his vintage know-how to a new level.  In 2009, he launched a wholesale wine portfolio and brand called Vino50 with Siema Wines. It was created to encourage consumers to explore local and regional wines. Vino50 celebrates the 50 States of Wine and Stover collaborates with wineries in budding wine regions to show consumers that fine wines can come from states other than California. Today the Vino50 portfolio represents over 20 wineries from 13 different US states.

" I have a horrible job. I get to tell stories, eat great food, meet incredible chefs and share experiences.  In the end, I get to call that work."  --Nick Materese

He grew up in food rich New York indulging in pizza, local foods & Finger Lakes wines before moving to Arizona.

The travel bug bit him and he spent several years working for a South African importer: driving a mobile wine lodge on wheels called "The African Queen 2" all over the USA for 28 months.  The opportunity to teach about food, wine, beer & spirits eventually brought to work for Siema Wines.

Barbara Gaiarin

European Logistic Director

Born in a small town on the border with Switzerland overlooking the Lugano Lake, at the age of 5 Barbara returned to the Veneto region, where the family originated. Growing up in a large family where everyone knew something about wine, after administrative studies and various work experiences, Barbara started her career in a winery in the wine-growing area of Lison Pramaggiore in the north-east of Italy. In addition to the administration, being a medium-sized winery, she had the opportunity to follow and learn everything about wine ... from the care of vine plants to the grape harvest and subsequent wine production.

Specialized in the foreign sector, Barbara has always followed the European and extra-European clients, actively participating in foreign fairs and exhibitions concerning the sector, and taking care of the organization. Barbara was able to specialize the knowledge of all the rather complex documentation necessary for the wine movement between the various countries as well as the organization of logistics. She’s had the opportunity to specialize herself also on the organic wine production, particularly in the management of administrative procedures related to it. In 2011 Barbara joined the Siema team as European Logistic Director.
