Dr. Robert "Bob Kelso" is the former Chief of Medicine of Sacred Heart on Scrubs and is played by Ken Jenkins.  Although Dr. Kelso is generally portrayed as mean-spirited and heartless, he really is just doing his job as the Chief and is looking out for the hospital's best interests.  Now retired, Dr. Kelso still hangs around the hospital and is much more human showing his softer side and ofering advice.

Kelso often refers to his obese wife Enid and his gay son Harrison, though neither have appeared on the show.
