At work at the hospital he is almost always seen wearing either blue or green scrubs with a long white lab coat over them. He wears a stethoscope around his neck and simple white shoes. Off work he is very casual, wearing relaxed fit blue jeans, hiking boots, a white T-shirt under a long sleeve flannel with the sleeves loosely rolled up to the elbows, and a ball cap.
He is somewhat of a mystery to those who work with him. Always thoughtful, quiet, extremely intelligent and dedicated to his studies and job, yet he is considerably the most unusual and odd in the entire hospital. He comes off as anti social some of the time. People often talk about the 'handsome, rugged' surgeon who shows up to work in a big red jeep stocked full with camping gear and the like, who sometimes shaves his beard in the public restroom depending how grizzly he looked, and who, without fail, brings books, cartoons, and games to the children's sick ward every other day.
His interests include being outdoors. He enjoys camping, hunting, fishing, hiking, climbing, and swimming. He likes to keep fit and go to the gym every now and again although he religiously jogs several laps around the park and down town before and sometimes after work. He enjoys all kinds of music and has taken a few dance lessons through the years. He's very ambitious and busy, although he often spends a lot of time outdoors alone.
He grew up in a well off neighborhood in Vegas with his 8 year old little brother named Dexter, and his dad. His mother died during Milo's birth and his dad never remarried. Felix felt a lot of responsibility growing up and was a bit of a loner. He worked through high school at a ski resort and achieved perfect grades upon graduation. He always felt pressure to be a doctor so he could take care of his family. He's been in a few short relationships and doesn't really seem interested in most women. He's not out for a fling, but a genuine woman who could appreciate and take part in all that he enjoys, but not many women enjoy camping and shooting/ eating little creatures.
