Bulwark really has a very thorough, dedicated, professional, friendly, knowledgeable technician in Derrick. We always enjoy having him out to the house, when he took care of us the 1st of the year he was so thorough inside and out we didn't see a single bug, until last week. We had the pleasure of a visit from him yesterday and he again helped us resolve an issue we were having in our attic. He is the Best! He helps us understand things easily as far as the type of bugs we periodically have and possibly why. We encourage you to train all your Tech's like Derrick. He's made life easier out here by the lake! Thanks Derrick, your the best!
