About Defensability

Hello, 
My name is Sean Grigsba. I am founder and co-owner of "Defensability".  My wife of 30 years and our 3 adult sons are owners as well and assist in teaching our courses. 
I live in North Central Oklahoma and have been in Law Enforcement for approx 17 years.  I started as a municipal Police Officer and am currently with the Sheriff's Office. Prior to Law Enforcement I worked and trained with an agency that specialized in advanced criminal interdiction.  
I joined the US Army in 1987 and was Medically discharged in 1989.  My sons are all currently serving in the US Army and the US Air Force. 
My family also owns and operates a security company that provides Armed Private security as well as Armed Executive security to our classified category of clients. 
I have a passion to teach and see others grow as they learn something new and exciting.  I have been providing training here to LEO officers for at least 10 years and feel that I will be for many more years to come.  I enjoy being around those that want to learn because I find that I too can learn from them.  You are never too good or too old to learn. 
In recent years I have been approached about providing firearms training to citizens that are looking for more than what they were given when they received their CCW permit from......."whomever". 
I feel that each responsible gun owner has the desire to learn more about how to protect themselves and their families.  We want to help.
