He grew up in Southeast Houston and moved in 2001 to attend the University of Texas at Tyler where he earned a Bachelor of Science in Biology/Pre-Med with a minor in Chemistry.  After graduating from his undergraduate program, Keanan began work as a biomedical research assistant at the University of Texas Health Science Center at Tyler.  He participated in biochemistry research for over a year then shifted his focus to clinical microbiology.  He contributed to a major research study and published in The Journal of Clinical Microbiology in 2010.
