Verizon Communications announced that John Killian will take over the role of chief financial officer, effective March 1.
Killian, who was also named executive vice president, will take over as CFO for Doreen Toben, who announced her retirement last week. Toben will continue to work with Killian until she retires around the middle of this year.
Killian is currently president of Verizon Business; Verizon said a replacement for Killian in that role will be named shortly.
As president of Verizon Business since its formation in 2006, Killian led an organization of more than 31,000 employees responsible for a global network that spans six continents. Before that, he served as senior vice president and chief financial officer for Verizon's Domestic Telecom group.
Killian began his communications career 30 years ago and held positions of increasing responsibility in operations and finance before being appointed president and chief executive officer of Nynex CableComms in the United Kingdom in 1995. He then served as group president of international telecommunications for Bell Atlantic before becoming the corporation's vice president for investor relations.
Following the Bell Atlantic/GTE merger that formed Verizon in 2000, Killian was appointed senior vice president of customer operations. He later served as senior vice president and controller for Verizon.
