Andrea Beceiro
Program Assistant

Andrea Beceiro is a proud student of The Honors Program at Miami Dade College, Wolfson Campus, pursuing a Bachelor of Science in Landscape Architecture.

For Environmental Sustainability Club at Miami Dade College. Her path to this point has been shaped and inspired by many activities growing up in South Florida including boating, archery, horseback riding, and volleyball, but she credits her love of all things green and her outlook on her future career primarily to her artistic and plant-loving grandparents.
