Fifth Grade


Arnel Greenberg

Hello. My name is Arnel Greenberg and I’m extremely excited to be joining the staff at Riverwalk Academy. I’m originally from Brooklyn, New York. I received my Bachelors Degree from SUNY-New Paltz and continued my graduate studies at UNC-Charlotte. I’m a lifelong Fellow of the Charlotte Teachers Institute at Davidson College. I am engaged to my best friend, Don Graham. I have a son & daughter-in-law with 4 ‘fur-babies’ and a daughter & son-in-law with my 2 grandsons. I enjoy cooking and exploring new places. I foster Greyhounds and volunteer with greyhound rescue groups for retired racers. After teaching kindergarten, 1st grade, 3rd grade, and 5th grade for 30 years in CMS, I am relocating to Tega Cay. My mission is to help guide my students along their individual paths of learning, model character education by being respectful & responsible, and celebrating both cultural & academic diversity while preparing them for their future.
