As a dramatist, St. Germain shows a strong preference for historical fiction.

His play Freud's Last Session premiered in the summer of 2009, at the Barrington Stage Company in Pittsfield, Massachusetts, and ran at the New World Stages in New York City. Freud's Last Session began its New York previews on July 9, 2010, and officially opened on July 22, 2010. In 2011, Freud's Last Session won the Best Play Award from the off-Broadway Alliance.

In 2011, St. Germain's play The Best of Enemies premiered at the Barrington Stage Company. Based on the nonfiction book of the same name by Osha Gray Davidson, the play dramatizes the relationship between C.P. Ellis (a local KKK leader) and Ann Atwater (an African-American civil rights organizer) during a racially tense period in the desegregation of Durham, North Carolina schools.

Becoming Dr. Ruth, which reveals the little-known but remarkable history of German-born Karola Ruth Siegel, who fled the Nazis in the Kindertransport before joining the Haganah in Jerusalem as a sniper and scout, struggling as a single mother in America, and, ultimately, becoming known as American TV sex expert Dr. Ruth Westheimer. The one-woman play (originally titled Dr. Ruth, All the Way), directed by Julianne Boyd and set in 1997, opened off-Broadway at the Westside Theatre in 2013. Other actresses to portray the role include Debra Jo Rupp, Eileen DeSandre at Virginia Repertory Theatre, and, in 2021, actress Tovah Feldshuh.

Scott and Hem in the Garden of Allah, premiering in 2013, explores an evening at Los Angeles' notorious Garden of Allah apartments with F. Scott Fitzgerald and Ernest Hemingway.

In 2014, St. Germain premiered his eighth play, Dancing Lessons, at Barrington Stage Company. The play ran from January 6 to February 7, 2016, at Orlando Shakespeare Theater as part of their 2015–16 Signature Series. The show was produced at Florida Studio Theatre in Sarasota, Florida as a part of their 2014–2015 Mainstage Season. Florida Studio Theatre has partnered with St. Germain to workshop many of his works in progress.

Recent works include Eleanor, a one-person show about the most famous First Lady in the world, which premiered at Barrington Stage and starred Harriet Harris; Dad, an autobiographical play, which was presented at Great Barrington Public Theater in 2021; and Public Speaking 101, which premiered at the Great Barrington Public Theater in the summer of 2022.

His relationship with Barrington Stage—the regional theatre where nearly all of St. Germain's recent works have premiered—was memorialized in 2012 when the troupe's Stage 2 venue was renamed the St. Germain Stage.
