Other Name: Project Dulce

Detailed Description:

To recruit 207 Mexican-Americans patients from federally-funded community health centers in San Diego County with Hemoglobin A1c (HbA1c) > 8% and randomize to Project Dulce peer intervention or continuation of standard diabetes care. The primary outcome will be the percent change in HbA1c levels at 10 months following randomization.
