After completing military service in 1992, she settled in Ogden, Utah, practicing at the Ogden Women’s Clinic and at Ogden Regional Medical Center and McKay-Dee Hospital until 2012; she later worked as an OB hospitalist, including at the Ogden Clinic. Lesser has also participated in medical volunteer work, including surgical outreach in Mali, West Africa, and emergency medical response following the 2010 Haiti earthquake.

Political career

Following the death of Rep. LaWanna “Lou” Shurtliff on December 30, 2020, Democratic delegates in House District 10 recommended Lesser for appointment; Governor Spencer Cox appointed her on January 16, 2021, and she took office during the 2021 general session.
In the 2022 [Utah House of Representatives election|2022 general election] she defeated Republican nominee Jill Koford with 52.3% of the vote.
In 2024 Utah [House of Representatives election|2024], Koford narrowly defeated Lesser in one of the state’s closest House races; canvassed county results certified Koford’s win and flipped the Weber County–based seat to Republicans.
Lesser served on several legislative committees, including the House Health & Human Services Committee and the House Political Subdivisions Committee.
She was elected Democratic caucus manager in late 2022 and served in the caucus leadership during the 2023–2024 sessions.
Lesser’s priorities included expanding access to health care, eliminating the state sales tax on groceries, strengthening early childhood supports, and clean air and natural resource protection. Commentators frequently noted her uncommon status as a Democratic legislator from outside Salt Lake County.
