Welcome to Mercer-Blumberg Learning Center at Saegert
MBLC is Seguin ISD’s non-traditional high school. Designated by the state of Texas as a Drop- out recovery school (DRS) of choice we provide a different and unique educational opportunity to the High School students enrolled in Seguin schools. Our goal is to provide an educational setting that is focused on the needs of each student. Our students work in a variety of settings that include: Project based learning, direct teach settings, and self-paced classes. In these settings students build strong connections and relationships with staff and other students. MBLC’s main purpose is to change the trajectory of our students by educating them with relevant coursework that prepares them for life outside of school and provides them options once they have graduated.
We do this by first helping students to earn their high school diploma. We encourage students to complete the foundation with endorsements pathway (26 credits), and when possible we help them earn the distinguished plan (DAP). In 2022 87% of our students completed the 26 credit plans and 84% were DAP.
MBLC’s second purpose is to help prepare or students for their future by assisting them in college admissions, TSI and EOC testing, as well as, applications, interviewing, and even learning about personal finances in the required personal financial literacy course.
At MBLC we specialize in finding every students’ potential and helping them to achieve their goals. So whether you are on track or way behind we can help you succeed. New in 2023 MBLC students will have the opportunity to earn their Texas Hunter & Boater education. If you are looking for something different in a family like atmosphere then MBLC is for you. All MBLC students: “Start Strong, Stay Strong, and Finish Strong!" Apply today!

Mercer Blumberg Learning Center is named after George Mercer Jr and Gilbert “Buster” Blumberg. Both of these men had the great gift of being able to connect with students and help them to be successful in school. Mr. Mercer and Blumberg were masters at finding ways to reach and inspire students, we are proud to work at a campus that carries their name, and the staff at MBLC work every day to continue these men’s mission of connecting with students and helping them to be successful.


George Mercer, Jr., began his 35-year career in education in Seguin in 1955 coming to the district with one year of experience in the Butler ISD. He taught science at Ball High School for 11 years until his move to Seguin High School in 1966. There he served as a teacher and as assistant principal until his retirement from full-time employment in 1990 at which time he began working as Assistant to the Director of Student Attendance. Mercer was born on January 10, 1928, in Hearne, Texas. He received his Bachelor of Science degree from Prairie View A&M in 1950 and his Master of Science in biology, administration and supervision in 1956. He held an elementary and secondary teaching certificate in all sciences as well as principal, administrative and superintendent certificates. He held professional membership in SEA, TSTA and NEA. He was a member of the Seguin Noon Lions Club, the Seguin NAACP, and the American Association of Retired People. He served the community as commissioner of the Seguin Housing Authority. He was also a member of the Greater Second Baptist Church in Seguin where he was a deacon, pianist for the senior choir, and financial secretary. In addition to his service to Seguin, Mercer served his country during the Korean War at which time he received the Purple Heart and the Combat Infantry Badge. He retired from the Army Reserves in 1976 as a lieutenant colonel. Mercer married Ethel Jones, and they had two children, Darrell and Sharita.

He was proud to have worked with the Texas Education Agency Office of Special Education in formulating guidelines and parameters for alternative school programs in the State of Texas. After 12 years, he left Seguin schools to teach in Judson ISD. Returning in 1989, Blumberg once again taught at Sue Smith. In 1992, he became Assistant to the Director of Student Attendance as the visiting teacher for Saegert and A. J. Briesemeister Middle Schools. Blumberg was born December 2, 1934, in Seguin.
