This is the start of my twenty-fifth year in education and the tenth year as an administrator; however, this is my third at Hannibal Middle School. Hannibal will be my 4th school I have served.  I have a specialist degree and a masters degree from Southwest Baptist University in Bolivar, MO.  My undergraduate degree is from Quincy University.   I am very excited to be here and look forward to bringing positive changes to an already great school. I have a wonderful administrative team and office staff to work with.  My wife is Holly and my kids are Natalie, Marshal, Glory, and Gabriel.

I am excited to be your child's assistant principal for the 2017-18 school year.  This is my 8th year as a principal and my 1st at Hannibal Middle School. This is my 18th year in the education field. I started my teaching career at the HMS where I taught 6th grade science for 8 years. I then went back to where I grew up in Illinois to be an Elementary and High school assistant principal. After 5 years in Illinois, I came back to Missouri to teach in Center. I taught one year at Center before becoming Elementary principal at Center for two years.

I grew up just across the river in Kinderhook Illinois. I graduated from Quincy University in 2000, and I received my Masters from William Woods University in 2006.  I have lived in Hannibal for 15 years with my wife Audra and three children. Allie is an 9th grader at Hannibal High School and my twins McKenna and Mason are in 6th grade at HMS.
