About Greta
After graduating with a degree in Acting / Directing from Mankato State University, Greta got her first professional job in 1989 touring with Small Change Original Theatre, an educational children’s theater company based out of Minneapolis. She also began improvising as an original company member of COMEDYSPORTZ MN. Greta moved to New York City in 1991 and, after a brief stint as a fragrance model at Macy’s Herald Square, began touring and performing with regional theaters across the country. She moved to the Twin Cities in 1996, where she still resides today.
Greta bought her first guitar while “on the road” and started writing comic songs. She recorded “Some of My Songs – by Greta” (on cassette!) in 1995, and used those songs to audition for Dudley Riggs Brave New Workshop, the oldest sketch comedy / improv company in the country. After a season at Dudley Riggs, she went on to spend five years with the Minneapolis production of TONY AND TINA’S WEDDING, to appear in the world premiere of the musical BINGO at the Ordway, and to originate the role of Mavis Gilmerson in all nine of the hit CHURCH BASEMENT LADIES musicals.
In 1997, she began performing with her sister as THE SILLY SISTERS. For 10 years the duo appeared at libraries, schools and museums, and also created original family-friendly programs for corporations around the country including SPAM, Gold-n-Plump Poultry and Target.
In 1999, Greta created her first one-woman show, I AM BECOMING, where she made an amazing transformation into seven distinct characters before the eyes of the audience. After performing her one-woman show at a company Christmas party, requests for other corporate appearances followed, and Greta began adding specialized content and training elements to her entertaining performances. In 2003, her first production company, GIRL WITH GUITAR, was born. The company provided specialized corporate entertainment and training around the country for a variety of clients including Andersen Windows, McDonalds and Honeywell.
In 2006, Greta continued her fondness for alliteration by forming THE LOONEY LUTHERANS. The comedy trio continues to perform across the country and are available for your special event!
In 2005, Greta’s career took a turn when she became the scriptwriter for the MEDORA MUSICAL, and she scripted the annual show for 18 seasons. In 2006, she began scripting the CHURCH BASEMENT LADIES musical franchise and has penned eight theatrical sequels and prequels that continue to be licensed across the country.
A member of the Dramatist’s Guild of America and the Playwrights’ Center, in 2007, Greta also became a member of Actors’ Equity, the union of professional actors and stage managers. In 2010, she served as Creative Director for the Minnesota Vikings 50th anniversary celebration and, in 2013, directed her first professional theatrical production.
In 2015, Greta formed Greta Grosch Presents LLC to produce her original musical, LEMONADE FOR THE LAWNBOY, and became the volunteer Chair of the Twin Cities AEA Liaison Committee. She continues to serve as an advocate for the Twin Cities theater community.
In 2022, she formed the production company IN THE BASEMENT PRODUCTIONS to produce an onscreen version of Church Basement Ladies and, in 2024, was nominated for “Best Direction of a Play” for two different productions. Her direction of URINETOWN made the “Best of Twin Cities Theatre list in 2025.
Greta continues to travel the country as a motivational speaker and corporate trainer, to serve as a scriptwriter for a variety of projects and volunteer where she can, and she enjoys working with young people as a coach and teaching artist. A prolific on camera and voiceover talent, Greta also appears regularly in television and radio ads and is represented by MOORE CREATIVE.
As an actor you generally submit your headshot, go to auditions, and wait for someone to give you a job. That can be really tough. Since the beginning I’ve tried to make my own opportunities and always have two or three new ideas waiting on the back burner. Stay tuned to see what’s next!
