Sara Mohr-Pietsch (born 1980) is a British music broadcaster who works principally for BBC Radio 3.
Mohr-Pietsch was born in London to a mother of Polish and a father of German descent. She read music at Newnham College, Cambridge from 1998–2001, where she was the first ever Newnham Choral Scholar in Selwyn College's Chapel Choir. After gaining a first class degree, she undertook an MA at Edinburgh University, subsequently becoming a tutor, a post she retained until 2006. While based in Edinburgh, Mohr-Pietsch embarked on a career in arts administration and began to broadcast on Radio 3, winning a BBC talent contest in 2004 .
After moving back to London her involvement with the network became more extensive. She became a regular presenter of the network’s Breakfast programme in 2007. Her fortnightly stretches alternated with those of Petroc Trelawny; previously Rob Cowan was the other regular presenter. In addition, she presents (with others) the contemporary music programme Hear and Now. Mohr-Pietsch began to present The Proms in 2008 on Radio 3, and on television for the BBC. At the beginning of December 2013, Clemency Burton-Hill replaced her on Breakfast.
She regularly presents Radio 3's "The Choir", and the Discovering Music series, particularly in programmes on Bach, whom she greatly admires and has studied extensively; early music is another interest. She is also a singer and pianist and plays the viola da gamba – "incredibly badly" in her own words.
In support of Red Nose Day 2013, Mohr-Pietsch set herself the challenge of learning eight notes on the cello in seven days, as part of a comic rendition of Pachelbel's Canon.
