Her past experiences include the 14th Street Y where she ran a retirement support group, the Sirovich Center where she did clinical work with adults with hoarding disorder, and NYU Langone Medical Center where she worked on the Adult In-Patient Medicine unit. Starting in 2019, Lexi became a Victim Services Volunteer at Mount Sinai Beth Israel where she received 40 hours of training to work with victims/ survivors of sexual assault. From 2016 to 2018, Lexi volunteered with Henry Street Settlement where she worked with students on the spectrum and students with behavioral challenges. Lexi founded the Lonely Hearts Club, a breakup support group, to help people navigate this specific loss.
