About Us

Security Insurance was located for many years in the Fort Pierre Bank before being purchased by Vern and Bob in 2012. At that time, it was renamed Security Insurance Group, Inc. (SIG) and relocated within The Ag Agency, Inc. office in Pierre at 3341 Airport Road. During that transition an office management software program was implemented, making for quicker efficient service. Security Insurance Group has 39 years of combined agent experience, with Bob having 25 of those years. We are proud and enjoy being an Independent Agency. Being an Independent Agency allows us the opportunity in offering you the best deal because we represent multiple companies. We strive to fully explain what is included, what options are available, and different levels that can be selected, when quoting or reviewing policies. Being insured at State minimums may keep you in compliance with State Regulations but could put you in a financially stressed situation when a loss arises. Consumers need to be aware that quotes need to have the same coverages and levels of insurance for pricing comparisons. Remember, quotes are free. Let us earn your business by ‘Protecting YOUR Peace of Mind’. Get started by contacting us today.
