Mariya Petukhova
is a data scientist. She also came to the U.S. in 2000 with her husband. She worked at companies like DRIVIN, Vivid Seats, and ShopRunner. The first week after the full scale invasion Mariya was collecting humanitarian aid. Then she came across J5 Rescue Supply and with their help and the chain of volunteers in Ukraine and Poland was able to start supplying tactical medicine directly to Kharkiv. She paid for the first order $8000+ out of pocket. She wasn’t sure the supplies would even make it to Kharkiv. They did. She personally made two trips to Poland and one to Ukraine to deliver supplies. On the last trip she visited Kharkiv and brought her grandmother to the U.S. to safety. Her mom and brother remain in Kharkiv. -
