Grant is a National Radon Proficiency Program Certified Radon Mitigation Specialist (#113687-RMS), certified since 2023. His combined background in field installation and operations management gives him a practical, systems-based approach to indoor environmental risk reduction across Southeast Michigan’s diverse housing stock.
Radon is a naturally occurring radioactive gas and a leading cause of lung cancer among non-smokers, according to the U.S. Environmental Protection Agency. Michigan contains many areas with elevated radon potential, with diverse housing stock spanning historic homes, mid-century construction, and newer developments throughout the Detroit metro region.
Grant’s radon mitigation expertise includes:
Grant’s design approach prioritizes long-term performance, system aesthetics, and minimal disruption to occupants.
In addition to radon, Grant oversees vapor intrusion mitigation projects involving volatile contaminants migrating from subsurface soil or groundwater into indoor air. Vapor intrusion is a particularly relevant concern in the Detroit metro region, where redevelopment of legacy industrial sites is common.
His vapor intrusion experience includes:
Grant ensures mitigation systems meet regulatory expectations, project aesthetics, and long-term durability standards together, not as competing priorities.
The Ann Arbor and Detroit regions include a significant number of historic and architecturally sensitive homes, many within designated historic districts with strict preservation requirements. Standard mitigation approaches that work on suburban new builds rarely fit these structures without compromising their character.
Grant has experience working within preservation guidelines and municipal historic district requirements to:
His understanding of permitting processes and preservation requirements helps streamline projects and avoid delays, especially on time-sensitive real estate transactions.
Grant holds active credentials through the National Radon Proficiency Program (NRPP), the credentialing division of AARST and the recognized authority for radon professional certification in the United States:

Yes. Many areas of Michigan have elevated radon potential, particularly across counties in the southern and western parts of the state. The EPA classifies several Michigan counties in Zone 1 (the highest of three radon zones), and radon levels can vary significantly even between neighboring homes. Testing is the only way to determine levels in a home or building.
Yes. Systems can be designed to preserve architectural features and comply with historic district requirements. Grant’s team has experience working within Ann Arbor and Detroit-area preservation guidelines, including securing appropriate permits, minimizing visible components, and routing piping to maintain architectural integrity.
Most residential systems are completed in one day. More complex or preservation-sensitive projects may require additional coordination, particularly for homes within historic districts where permits and design reviews are part of the process. Vapor intrusion mitigation on commercial or redevelopment sites typically involves longer timelines and consultant coordination.
