Some contractors hand the job off after the contract is signed. That is not how we operate.
At JMG Builders, we manage every aspect of each project ourselves. This hands-on approach allows us to maintain quality control, stay involved in the details, and keep communication clear.
We also treat every client like family. We believe trust and long-term relationships matter just as much as the final result.
what that means for you
Owner Jon Graff was raised in Medford, WI, and grew up working alongside his father in a general contracting business. Those early years shaped how Jon approaches building today.
Jon earned an Associate of Applied Science in Architectural Design and Technology from Northcentral Technical College in Wausau. After more than 15 years of field experience in the home construction industry, Jon started JMG Builders on 2021.
The name JMG Builders honors Jon’s father, Jack Michael Graff, and the work ethic and integrity he passed down.
Today, JMG Builders is known for high-quality remodeling and custom home building throughout the Chippewa Valley.
