Charlie Christionson was a Starfleet medical officer.
He was born and raised in the city of Toronto, Canada. Once of age he joined Starfleet following in the footsteps of his father, Nick Christianson, who is a high ranking member of Starfleet security. Even though his father hoped he would become a security officer he became a doctor instead.
CMO of the Eagle
In 2269, Commodore Shrelic requested that he become the chief medical officer on his first officer Zach Banner’s new ship, the USS Eagle. But Mr. Christianson was already serving on the USS Rossbach on a deep space mission and would not be back in time for launch. Instead, a Lt. Miller was given a temporarily promoted to lieutenant commander for the first few weeks of the Eagle’s voyage. Once he returned for deep space, he took his position on the Eagle as chief Medical officer.
In early 2270 the doctor accompanied the captain on bored his old ship, the USS Bismarck. Unknown when they beamed over the ship was controlled by an insane alien computer. He and Michele Tyler were sent down to back up control to deactivate the shields so they could beam back to the Eagle. Once there the alien computer caused the control panel to explode seriously hurting Ms. Tyler. He was able to keep the commander alive long enough for the captain to destroy the computer and beam back to the Eagle.
During a mission to pick up classified cargo from Epsilon Indi IV, Christianson and Clause Elberg were kidnapped by a group of pirates. Once onboard, they found it was one of Elberg’s former officers, Nick Sather, who had defected. When the pirates were about to have Elberg and Christianson subjected to their stolen klingon mind-sifter, the two were able to escape. Elberg found a power sub-junction and was able to temporarily shut down the pirate vessel’s cloaking device, making it possible for the Eagle to find them, but Sather was still able to find Elberg and bring him to the interrogation chamber while Christianson was able to fined the stolen cargo. However, the Eagle was able to fined the pirate vessel and rescue the two Starfleet officers.
