Mr. Roger Gambrell

I am a native Houstonian and graduate of Robert E. Lee High School in Houston.  Teachers have played a pivotal role in shaping the person that I am today.  Without the outstanding teachers that I have influenced me, I would not be a teacher today.  I have been a teacher for 22 years.  I began teaching in Houston ISD at Worthing and Jones High School.  This is my fourth year at Marshall High School.  Parents, please feel free to contact me via email or meet with me during my conference period (7:30 - 8:15am).  Your child's success and development are my highest priority.
