Gretchen has her Master's Degree in Performance Studies from Northwestern University where she studied text analysis with Frank Galati and movement techniques with Mary Zimmerman. She also trained at Circle-In-The-Square Theatre School in New York City, studying both Uta Hagen's and Mira Rostova's systems.
In addition, Gretchen enjoys artistic forays into playwriting (including her play The Psalm of Levi Yoder at Northwestern University, which starred Annabel Armour and Jane Heitz), memoir writing (she's working on her first book), and the adaption of oral histories for the stage. Gretchen also integrates the physical aspects of the performer through her study and teaching of yoga, having received her teacher certification from the Chicago Yoga Center in 1997.
