AHI ENVIRONMENTAL - Key Persons


Heather Harper

Job Titles:
  • Operations
Heather Harper is the person who makes everything happen behind the scenes (and keeps John on track). On a typical day you can find her logging samples, following up with labs, confirming appointments and the like. She's experienced first hand how little improvements to the environment can help you feel better and understands that while it might seem like a good idea to fix everything all at the same time, it's not always a realistic goal… over time little improvements really can make a big difference.

John Crewdson

John Crewdson is an Indoor Environmental Professional (IEP) performing Chemical, Biological and Electrical assessments in the Metro Atlanta area. With over 30 years of experience in residential and commercial construction and inspection, he knows a thing or two about where problems hide and about fixing them. While doing forensic testing on commercial and residential buildings, he learned about sick buildings and that the industry wasn't doing much to make the buildings better. He's been very fortunate to study with some of the best and most seasoned IEP's and Building Biologists in the business. He's always had an interest in alternative health and over the years that interest moved into how our homes should support our health. Now he spends most of his time uncovering specific toxins and educating clients about how to make their homes healthier places to live.
