Dmitri was born in Hornsby, a suburb of Sydney, Australia back in March 1996, named after his recently-deceased paternal grandfather. His dad spent most of his time away, as was part of being in the navy, and when he came back, he and Dmitri would spend a lot of time together. His sister, Maddie, was born in 1998, and she spent most of her childhood trying to get Dmitri in trouble. As a result, the two of them argued a lot, and Maddie became more of a mummy's girl, while Dmitri preferred to spend time with his father.
His parents grew distant over the years, but decided against getting a divorce since it would just make things difficult for everyone involved. His brother Keegan, was born in 2002, although suspicions were raised about whether he was actually Andrei's son, or if Jill had been having an affair. Dmitri wasn't highly popular throughout school, but nevertheless, he managed to have three brief relationships with different girls, only having sex with his tenth grade girlfriend, Olivia. In 2013, his father retired from the navy after serving for twenty-five years, and after struggling to deal with the new living conditions, Dmitri's mother, Jill, filed for divorce, opting to take up a job offer in Barfield she'd recently been offered, and taking Dmitri, Maddie and Keegan with her.
Since moving to Barfield, Dmitri met Kat, Prue, Nadia, Rosalie and Lexi, developing a romantic relationship with Kat. At some point he took up smoking, cigarettes and marijuana, to combat the boredom of repeating his senior year despite being months off graduating, but kept this hidden from Kat. Midway through the year, he made plans of joining the army after realizing that his mother had spent his university fund on moving out to Barfield. After graduating, however, he changed his mind about this and worked on getting a job closer to home so that he and Kat can move in together and away from their families.
