• Hello, my name is Sarah Keller-Gelbart. I began at T.H. Rogers in 1885 as a preK RDSPD teacher. I left after my first child was born. I returned as a substitute when she was a baby. Then returned as a fulltime RDSPD teacher after my second child entered first grade in 1998. I have worked in four states, Illinois, Missouri, Ohio, and in Texas. I have lived in Texas for 33 years. My Bachelor Degree was in Elementary Education/Deaf & Hard of Hearing. My Master Degree was in Special Education (Behavior Disordered/Learning Disabled).
