EMF Testing Technician ACES
Following a personal journey through chronic health challenges, Marco transitioned from large scale electrical installation work to the study of Building Biology. He realised that for those navigating recovery from chronic illness, the home must be a true sanctuary—free from the environmental stressors of the modern "wired" world.

Tiffany Hill
B Int. Arch. (Hons) UNSW
Adv. Dip. Building Biology ACES
EMF Testing Technician ACES
Tiffany is a core member of the Spectral Design team, specialising in comprehensive electromagnetic field assessments for health-conscious families and individuals. Undertaking further training under Spectral Design Director Marco Simeoni, Tiffany combines technical precision with a deep understanding of how environmental stressors impact human biology.
With a Bachelor of Interior Architecture and a decade of professional practice, she understands the "bones" of a building. This architectural foundation, paired with her advanced certifications, allows her to provide mitigation strategies that are both scientifically sound and practically integrated into your home’s design. Tiffany’s commitment to Building Biology isn't just professional—it’s personal. Diagnosed with an autoimmune condition at age 13, she spent years investigating the environmental triggers that affect wellness. While raising her young family and navigating her own home renovations, she solidified how managing the "electroclimate" of a home is one of the most vital pillars of long-term health. Now, as an EMF Specialist at Spectral Design, she combines her training at ACES and utilises the advanced methodologies developed by Marco Simeoni to help Sydney residents identify EMF stressors in their living and sleeping environments.
