Anna Sawicka (Anka), Architect

Anna Sawicka (Anka), Architect is a Job Captain at a New York Architectural firm. She immigrated to the US at age of sixteen and encountered her first task of navigating a high school labyrinth of corridors and, of course, an unfamiliar education system. 

Although declaring major in Math in Computer science in Poland, where she is from, and showing great inclination for sciences, especially Chemistry, during High School, and winning multiple art contests, she has decided that she is looking for something greater, a field that unites all fields and is a feast for a Renaissance man or woman. She decided to marry her love for art, sciences & humanities and major in Architecture. Five years later, in 2012, she graduated from the PRATT Institute and has worked within the field since. She had an opportunity to work in various size firms, both Residential and Commercial, ranging from private to public and high-end to more budget conscious. 

Besides her academic work, she has committed herself to various non-for-profit and volunteer work. She is a member of Polish Scouting Organization, used to dance traditional dances at PAFDC, and volunteered during film festivals. She is founder of the Father Popiełuszko Square, a member of the board of Polish National Home in Greenpoint NY, and a leader for emergency relief fundraising efforts. During her time at PRATT Institute, she coordinated tutors who were a part Tutoring Program for Structural Courses, as well as tutored the students herself, she graduated with highest honors and received Henry Adams Award & Medal. She spent one of the semesters at PRATT participating in the study abroad program in Rome where she spent her time learning the culture, language and architecture.

 In her free time, she loves reading, learning new things (currently Japanese), hiking, swimming and travelling. All the above-mentioned help her develop her passion for architecture, science, art, archeology, environment, sustainability, outdoors and teaching next generations and help them achieve their potential best.
