Sheree M. Mitchell, President & Founder

Sheree M. Mitchell has traveled to 40 countries, lived on three continents and speaks English, Spanish, Portuguese and some Italian. In her early-thirties, she gave up a comfortable life and career in Miami to embark on a year-long solo sojourn around the world that changed the course of her life. Today she’s the managing director of Immersa Global (USA) and SMM Advisory (Portugal), two boutique firms that specialize in designing and executing exclusive experiences for discerning travelers. Mitchell is considered as a thought-leader in highly-curated travel and in extended solo travel. She speaks regularly on these two niche markets at the New York Times Travel Show, the Travel & Adventure Show, as well as various tourism conferences throughout Europe. Most recently, Mitchell has been invited to design projects that use tourism as a vehicle to connect cities in the US with cities in Portugal at the local government level.  

She holds two BAs in Latin American Studies and Spanish and a MA in Spanish Literature and Pedagogy. As the "creative brain" behind Immersa Global's programs, she happily bounces around the globe visiting different program site locations and laying the groundwork for future projects.  During her free time you can find her smiling and laughing, creating new projects, or sipping on a glass of Portuguese wine (...or all three at the same time).

Ana Nogueira, Portugal Program Director  

Born of Portuguese heritage and raised in Mozambique, Africa, Ana has always been fascinated with exploring the world. She has traveled to 27 countries and when she’s not on the road, she happily shares her beautiful city of Lisbon with visitors from around the globe.  

Ana's passion for globetrotting led her to study Hospitality Business Management. She has acquired vast experience in Quality Assurance, Management Systems, Customer Satisfaction, and Food Safety Management. Most recently Ana has combined all of her experiences and realized her life-long dream by creating an upscale hostel in a beautiful historic building in one of Lisbon’s most affluent neighborhoods.  This innovative concept of high-end yet affordable short-term lodging has been so successful that Ana just recently acquired and opened more residences throughout Lisbon.  

Ana's love of sharing Portugal with the world is palpable.  On any given day, you’ll see (or hear) her happily indulging her guests at Royal Prince Hostel with regional baked goods, mini Portuguese lessons or impromptu wine tastings.  (All of which she does while skilfully switching back and forth from English to Spanish to Portuguese!)

Gabriela Adarve, Business Development Manager

Native Floridian and first-generation American, Gabriela’s first experiences with international travel began with trips to her parents' hometown of Bogotá, Colombia when she was just a few months old. She surprised her mother and relatives alike when, at four years old, she began reading restaurant menus in Spanish--which she spoke fluently thanks to her bilingual upbringing, but had never been taught formally. Gabriela's fascination with language and culture followed her into young adulthood. In 2014, she placed second at Valencia College in Orlando, Florida for presenting an award-winning speech commemorating International Education Week. She graduated with her B.S. in International Affairs from Florida State University in 2017, with nine years of French language and a semester overseas in Prague under her belt. She put her language skills to the test that summer in Paris, navigating the city while keeping a vow to herself to do so without speaking a word of English.

Today, Gabriela is based in the Miami area. Whether she is enjoying a weekend in Wynwood or bronzage at the beach, an afternoon in the vineyards of Germany or a film festival screening in Los Angeles is not too far off her radar.
