The Loudoun County School Board approved the reassignment of three of its principals during a meeting in late February.
Broad Run High School, Stone Bridge High School and Newton-Lee Elementary School will all be under new leadership this fall.
Stone Bridge Principal James Person will retire June 30 after a 40-year career in education.
Person, who is one of the longest tenured principals in Loudoun County at their current school, is retiring after 36 years as an administrator in Loudoun County.
Person has been an assistant principal in Loudoun at Park View High School, Loudoun Valley High School and Loudoun County High School.
In 1991, Person returned to be the principal at Park View, where he remained until 1999.
In 1999 he began planning to open Stone Bridge, where he has remained for 15 years as its first and only principal.
Broad Run Principal Doug Anderson, who has been at the school since 2004, has been appointed as the new principal at Riverside High School, which will open in 2015.
Anderson has been the principal at Broad Run since 2010, after serving as an assistant principal at the school for six years.
Newton-Lee Elementary School Principal Carol Winters will also retire from a career in education.
Winters is concluding a 41-year career, 24 of which were in Loudoun. Winters has also taught in Pennsylvania and Baltimore, Md.
In 1990, Winters moved to Loudoun County, teaching kindergarten at Arcola Elementary. She has also worked at Sterling Elementary and Algonkian Elementary.
She became the assistant principal at Lowes Island Elementary in 2001 and took the same position at Countryside Elementary in 2003.
She became the principal at Hamilton Elementary in 2006 and moved to her current position at Newton-Lee Elementary School in 2009.
