From the time Jim Kerwin graduated from St. Mary’s College of Maryland in 1986, he knew he wanted to combine his passion for art with his degree in economics. The home building field offered the perfect environment to do just that. The art and science of home building requires vision and expertise to translate the architect’s blue prints and the engineer’s site plan into a reality.

Jim, with his wife and business partner, Pam, will do everything possible to make your home building experience a positive one.

With over 25 years experience in residential home building, 16 years of which was for a national builder as a project manager, Jim has been responsible for building over 400 homes and was inducted into their “Master Builder Society” for exceptional performance in quality and cost controls, outstanding customer service and volume of units constructed. Jim also developed and conducted training seminars for other project managers.

At Decatur Building Services you get the benefit of Jim’s vast experience as well as personalized attention from design to delivery.
