The Team Behind ISM Construction

Led by Ivan and Josiah Martin, ISM Construction has served Lebanon County homeowners since 1994. As a family-owned and operated business, we believe building homes is about relationships as much as construction.

Ivan began his work in construction in 1983, and after 11 years he founded ISM Construction. His relationship-based approach to building has made ISM what it is today.

Josiah grew up working in construction with his Dad and has been a part of ISM for the past 15 years. He and his wife Megan have been married for 14 years and are raising six children right here in our community. That commitment to family and community shapes how we approach every project.
