Meet The Owner

Javondlynn (Lynn) Dunagan (a certified NRA Firearms Instructor) retired in January 2016, after a successful 25-year career as a United States Federal Probation Officer in Chicago, Illinois. She started JMD Defense & Investigations, LLC after noticing a lack of women at the shooting range and realizing that other women shared her former fear of firearms. Lynn discovered that responsible firearm education was missing from the Concealed Carry conversation.  

Lynn realized that female self defense classes were an unmet need in her community. As a result, she sprung into action and created a business model that sets the industry standard for safe, responsible firearm ownership and handling. JMD is uniquely focused on empowering women of all ages for personal security, protection and defense. 

Lynn is guided by her commitment to offering services to customers and clients with an uncompromising level of integrity. 

JMD Defense & Investigations, LLC is certified by the City of Chicago as a Minority-Owned Business Enterprise and Women-Owned Business Enterprise.
