Under the same contract, she develops data quality resources for users of the TAF files and spent four years providing technical assistance to states on their T-MSIS submissions. She led analyses of children’s use of behavioral health care during the COVID-19 pandemic and of home- and community-based service use in Medicaid for the Office of the Assistant Secretary for Planning and Evaluation. Sanchez also serves as a metrics subject matter expert for substance use disorder demonstrations under the 1115 Demonstration Support Contract.

Before joining Mathematica, Sanchez interned with the U.S. Department of Health and Human Services’ Office of Inspector General, Office of Evaluation and Inspections, and before that she managed a community health program in Chicago.
