Bobby is a dedicated fire fighter, and Captain of Station 118. He holds himself to a high standard, and expects his fellow firefighters to do the same. He is fair but strict, calm during stress, and even though he is a bit of a loner, his crew likes and respects him.

Bobby moved to Los Angeles after a family tragedy in Minnesota. His wife and children died after their building caught on fire. Lingering pain from an on-duty injury left Bobby with an addiction to pills and alcohol, and he had fallen asleep on the roof. When the sirens finally woke him, it was too late for him to save his family. He shouldered the blame for the fire that killed 148 people, even though an investigation revealed numerous building code violations that contributed to it. He attends AA, and has his addictions under control.

He is married and very much in love with his new wife Athena, a Sergeant in the LAPD.
