James Brock, Student Security Officer

After I graduated from Soddy Daisy High School in 1980, I enlisted in the United States Army for 4 years. When I returned home I became a Police Officer for Chattanooga Police Department (CPD) where I would stay for the next 25 years. During my career with CPD I had the opportunity to work in various divisions. I served as a Patrol Officer, Mounted Patrol, Narcotics, Special Operations, Bike Patrol, S.W.A.T. The last 5 years with CPD were in the training division where I served as the Range Master and Lead Firearms Instructor. After my retirement from CPD I packed up and headed to Iraq to work as a private contractor. In Iraq I served as a body guard for the US State Department and then as Range Master at the US Embassy in Bagdad, Iraq. Upon my return to the States, I became a Sheriff’s Deputy with the Hamilton County Sheriff’s Office. I worked as a School Resource Officer (SRO) and was assigned to Tyner High School where I have spent the last 7 years before retiring from Law Enforcement.

I am excited to be working for Hamilton County Department of Education as a Student Security Officer (SSO). I look forward to being part of making sure our schools are a safer place for both our children and teachers.


Michael Darty

Michael Darty Student Security Officer

I am excited for the opportunity to be a School Security Officer for the Hamilton County Schools as it allows me to maximize my past experience in both security and education. I served as a police officer for ten years where I commanded the SWAT team and supervised the E-911 system. I am also a current member of the Alabama National Guard, where I have served for 32 years as a military police officer, Security Advisor and Senior Religious Affairs Advisor. I am particularly proud of my two post 9/11 deployments: Operation Noble Eagle (2001-02) where I was responsible for security for Alabama’s five commercial airports and Operation Enduring Freedom (2013-14) where I commanded the soldiers and contractors operating the Persistent Surveillance System at Camp Bala Hissar, Afghanistan.

I am also a certified teacher for grades 6-12. I taught history for 17 years at Pleasant Grove High School, a 5A school in a Birmingham suburb decimated by the April 2011 tornadoes. I also served as the Head Varsity Soccer Coach and an Assistant Coach for both the high school and middle school football teams. I retired in August 2020 from the State of Alabama.

A native of Carbon Hill, Alabama, I graduated from the University of Alabama with a degree in History. Roll Tide! After living in Vestavia Hills (a Birmingham suburb) for almost 20 years, I relocated to Chattanooga in Summer 2020 after my wife accepted a job with McKee Foods. My wife is an attorney and family-business consultant. My daughter is a sophomore at the University of Mississippi in the Early-Entry Pharmacy Program and my son is an 8th grader at East Hamilton Middle School. As a family, we love to attend sporting events (especially Alabama football and professional soccer) and travel. We are also huge Disney World fanatics and have been every year since 2005. I also enjoy hunting and woodworking.
