He spent his formative years on Andoria. His father Brycke was an miner and also had been a smuggler in the past.
Not wanting to stay on Andoria, at age 15, he got a job on a freighter as a deck hand.
He then transferred to the USS Expedition (NCC-76277) and served with a number of officers including Captain Vanessa Ann Lucifel and Commander Ashley Morgan. It was aboard the Expedition that he became an accomplished pilot. In 2379, he successfully navigated the Expedition to the Delta Quadrant. At the Malon homeworld, they instituted a waste management plan for the disposal of the race's radioactive waste. Due to his piloting skills, in 2380, he was promoted to Lieutenant.
In 2386, Teshurr made the rank of Lieutenant Commander. After returning from a mission in the outer fringes of the Delta Quadrant, the Expedition was destroyed defending space station Deep Space 10 in the Delta Quadrant.
The next year, Commander Teshurr took the USS Crusader to the Talos star group in search for Captain Candela Greene and Lieutenant D'Real. Even though he rescued both, he was stripped of command for violating General order 7.
It was later revealed he was reassigned for a spy mission to infiltrate the Orion Syndicate in the Ventrax star station. Within 5 months, he thwarted a plan to strand Captain Candela Greene and Lieutenant Eric Kramer on Ceti Alpha V to die. Captain Greene would assume command of the Crusader following this incident.
