Anders Kristiansen was born in Kopenhagen, Denmark to Katia and Kasper Kristiansen. He had a younger sister who he was very close with despite not having grown up together. This was a result of his parents splitting apart at age 8 due to the infidelity of Kasper. When the two parents split, Kasper took Anders with him and Katia took Stella. Kasper, who was a successful orthopedic surgeon, took a job in the UK working as the head of the medical staff at a football club in London. This is where Anders would spend the formative years. While he participated in football at the urging of his father, he was never too interested in it outside of a fun activity. Where he really excelled and what he truly enjoyed was learning. His father was abusive and an alcoholic and these would leave their marks on Anders.

He was several grades ahead and graduated from Stanford at 18 before attending medical school at the University of Washington. While in medical school, his father would kill his mother in a spite of rage when he found out she was remarrying. Ultimately, he would kill himself to avoid capture. For these reasons, Anders swore off relationships citing divorce and domestic violence rates. He would continue on to achieve his residency/fellowship in cardiothoracic surgery before moving to LS where he took a job at Pillbox Medical Center.

After several months, Pillbox was closed down and he would move to Mt. Zonah where his life would change forever. While attending to her injuries after a drunk car accident, Anders would meet Poppy Hill whom he would grow quite close to over the next few months. Eventually, causing Anders to forsake his old vow agaisnt all relationships. The two would lead a happy relationship until Anders was murdered on August 8th, 2021. Prior to that, Anders would be investigated for corruption because he took out a substantial amount of medkits after a friend asked him if there was a limit. Despite having never sold a medkit, he would be suspended from his job. During this time, he had several different groups: Gangs, MCs and individuals all approach him about selling and he never did. One of these individual would shoot and kill Anders after he once again refused to give him what he wanted.

With his dying words, Anders gestured to his pocket and told Poppy that he loved her. She would find an engagement ring inside. Shortly after, Anders would die. His murderer would be caught where he pled guilty to the murder and spend the next 30+ years in prison. Anders would be buried in LS.
