Led by award-winning bartender Sarah Madritsch — we bring concepts to life through strategy, design, and expertise.

Originally from Bangkok, Thailand, Sarah Madritsch began her hospitality career at Tropic City, one of Asia's most celebrated cocktail bars. The venue earned consistent placements on the Asia's 50 Best Bars list and was nominated for Best International Cocktail Bar at the Tales of the Cocktail Spirited Awards.
In 2019, she moved to Zurich and joined the acclaimed Widder Hotel, where the bar received a Tales of the Cocktail nomination, a listing in World's 50 Best Discovery, and accolades from Gault&Millau and Falstaff.
In 2022, Sarah joined IGNIV Zürich, the city's renowned two-Michelin-starred restaurant, where she was named Barkeeper of the Year Switzerland 2022 and received the award for Best Bar Menu Switzerland 2024.
With over a decade of experience across cocktail bars, five-star hotels, and Michelin-starred kitchens, Sarah now works as a gastronomy consultant, holder of Swiss Federal Diplomas (eidg. Fachausweise) as a Gastro-Betriebsleiterin and Sommelière, and an award-winning barkeeper. She is currently pursuing a Bachelor of Arts in International Management.
Sarah specializes in beverage concept development, operational optimization, and guest experience design, partnering with hospitality brands to create strategic, sustainable, and guest-centered concepts.

At Madritsch Gastroconcepts, our mission is to empower both newly launched and established hospitality businesses with tailored, innovative, and results-driven consulting solutions.
