Maryland BioDectection recently inspected my home as my family was having some health concerns. Keith Oltman performed a professional detailed assessment of my home and through his expertise was able to locate elevated conditions that existed in our home. Mr. Oltman provided a detailed 20 page report that included all his findings and recommendations for remediation. We are truly greatful that we used the services of Maryland BioDetection and would rate them tops in their field. I recommend anyone with a possible indoor air quality concern to contact Keith for an assessment as well.
