Doug Berry, founder and owner of First Line Security

Doug Berry of First Line Security

First Line Security is owned and operated by Douglas Berry of Walkerton.  He started the business in October of 2004.  He had previously owned an electronics repair business for many years. 

Douglas has lived in the Walkerton area all of his life.  He attended Walkerton District Secondary School and then received his electronic technician degree and started his own repair business.  He has three children.  A son, Jason who with his wife Suzanne and daughter Adrianne live in Vancouver.  His other son Matt and his wife, April along daughter Cali and son Levi live in Walkerton.  Matt and his wife had been living in Kitchener for several years but decided to move back to Walkerton to raise their family.  It was good timing as Douglas was getting busier and needed extra hands to keep up with the security and medical alarm installations.  Douglas also has a daughter April, and she lives and works in London.

Doug’s wife, Marlene, takes care of the office and bookkeeping. 

Douglas believes that being local is very important and that word of mouth is his best form of advertisement.  If a customer is happy, they will recommend First Line Security to their family and friends.
