  • Hiring, training, and certification of SAC tutors.
  • Management of student progress in tutoring.
  • Providing equitable academic support for all students in need of tutoring services at SAC, including those needing additional resources and support.

I started working at San Antonio College in June 1991 and have never left. During the first 11 years, I worked as a part-time tutor helping students in areas such as mathematics, accounting, physics, chemistry, and engineering (pretty much anything math related). Since 2002, I have worked full-time in the S.L.A.C. performing duties such as webmaster, programmer, database administrator, Navigate administrator, tech support, tutor supervisor, and trainer.
