## Early life and education

She was born Karen Jill Stein in Newport News, Virginia, in 1954. She is the oldest of four children. Her father, a PhD in engineering, worked at NASA.
She graduated from Hampton High School and entered the third class opened to women at the University of Virginia, in 1972. She graduated in 1976 with a major in applied mathematics and minor in electrical engineering. She was one of the first 10 women to graduate in engineering from that university. She began working at Duke Power Company in Charlotte, North Carolina, and went on to earn her MBA at the University of North Carolina at Charlotte in 1979.

## Career

After five years as a planning engineer with Duke Power, she moved to Denver, Colorado, in 1981 to become a planning analyst for Mobil Oil Corporation in the company's mining and coal division. As the energy business took a downturn in 1983, the following year she entered consulting work for electric utilities as assistant vice president of Stone & Webster Management Consultants in Greenwood Village, a position she held from 1984 to 1992. From 1992 to 1995 she was a principal with RCG/Hagler Bailly in Boulder, managing utility planning. She returned to Stone & Webster to run their Denver office from 1995 to 1997. During the latter period, she served as an expert witness for electric utilities before Federal and state regulatory commissions.
From 1997 to 2000, Tietjen turned to women's education as director of the Women in Engineering Program at the University of Colorado Boulder. Between 1997 and 2008 she was an accreditor for engineering programs nationwide, including those on behalf of the Institute of Electrical and Electronics Engineers (IEEE).
In 2000 she formed her own company, Technically Speaking, Inc., to provide consulting services to electric utilities. From 2001 to 2008 she worked as a senior engineer at McNeil Technologies, and from 2003 to 2005 as a senior management consultant at R. W. Beck.

## Women's advocate

Tietjen is a strong advocate for the participation of women and girls in the STEM fields. She mentors women and girls considering careers in engineering and technology, and has endowed scholarships for women in technology fields at the University of Virginia, the University of North Carolina at Charlotte, and the University of Colorado Boulder, as well as through the Society of Women Engineers. With an eye to supplying more role models for women, she regularly nominates candidates for awards and halls of fame in the engineering and technology fields. Her first nomination was for computer scientist Grace Hopper, who invented one of the first compiler related tools in 1952. In 1991 Hopper received the National Medal of Technology. Tietjen accepted the award on Hopper's behalf from President George H. W. Bush at a ceremony in the White House Rose Garden. Tietjen has nominated more than 30 inductees to the National Women's Hall of Fame across all fields of endeavor.
