  • MilMar owner Marvin Miller has been in the construction business since he was 18 years old and will work to ensure that every detail of your building is constructed according to specifications and National Building Code standards and to your satisfaction.
  • 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!
