Security You Can Trust Since 1953
Per Mar Security Services was founded in 1953 by John and Eleanor Duffy in Davenport, Iowa.
Per Mar was originally chartered as a security and investigative business.
The business started out in John and Eleanor's home on 804 Iowa Street in Davenport, Iowa. To this day, Per Mar is family owned and operated by the Duffy family.
We have grown to become the largest family owned, full-service security provider in the Midwest.
Our company has grown through steadfast dedication to our community, employees and customers.
