  • Jack McDonnell, Marvin’s brother-in-law, is MilMar’s building consultant/sales rep. Jack has many years experience working in the construction industry and is very knowledgeable about post frame construction and home renovations. Jack can answer any questions you may have about the details of your building before construction. And if he doesn’t know the answer to your question, he’ll find out for you!
