CSM (R) Richard Sizer


I retired from the Army after 27 years of service as a Military Intelligence Professional. I'm a Jersey boy who decided to retired in San Antonio, TX, "Military City USA". I've been a Johnson  JROTC Army Instructor since 2011. I've also served as a Senior Instructor at the Army's Military Intelligence Center of Excellence in Fort Huachuca, AZ.  I am married with two boys, both are Johnson graduates. I am truly grateful to be given the opportunity to coach, teach and mentor young adults here at Johnson High School.
