Saving Vanessa Marianna
Rosenberg was contacted by James Wesley when Wilson Fisk's lover Vanessa Marianna was poisoned at a fundraiser. When he arrived from Hartford, Connecticut he took control of her surgery and eventually saved her life. Once Marianna's health was stable, Rosenberg personally informed Fisk that his beloved was going to be alright, causing Fisk great relief. Fisk shook Rosenberg's hand and thanked him personally for all he had done for her.
