The New York Times has described Markey variously as "hilariously sociopathic"[1] and as having "a cult following as an alt-cabaret star with swaggering confidence and off-kilter sense of humor.

[2] In high school, Markey flirted with being a "Bible Belt Christian," due to the influence of friends and their sense that " it felt like really impassioned, relatively speaking, to Catholicism.

[2] After college, Markey worked for five months at a strip club, an experience that, according to a profile in The New York Times, was "helpful in developing her [sic] confidence and stage presence."

"[5] Michelle Tea wrote favorably of Puppy Love, calling it "innovative" due to its unusual treatment on the topic and also praised Markey's voice.

[6] In 2013, Markey starred in Progressive Theatre Workshop's God Hates This Show: Shirley Phelps-Roper in Concert, Live From Hell, a musical written and directed by John J. Caswell, Jr. that satirized Westboro Baptist Church.

On January 13, 2016, Markey's show A Ride on the Irish Cream, which was funded in part by an Indiegogo campaign, premiered at the Abrons Arts Center of the Henry Street Settlement.

A live band and original score become the space for the thrills and terrors of a relationship between Reagan (Markey), a vainglorious self-made girl, and Irish Cream (Becca Blackwell), her family's pontoon boat/horse.

They are in love, but when their relationship is tested by dust ruffles, sex for money, severe T-storms, and a secret cellar, the only way to stay together is to remember all the parts of themselves their bodies tried to forget.
