Thank you so much Bio-One for helping me when times got hard! They were truly there for me and actually cared about what I was going through. They can get any job done and do fantastic at it. Thank you
Logan Vogt
This company is AMAZING! They sent me a quote right away, based on pictures that I sent. They scheduled the clean up the same week. The crew worked their butts off and the end result exceeded my expectations, like WOAH!!!!!!!!!! They were very professional, compassionate, and tender in dealing with a sensitive issue and emotions, and left the feeling of dignity and respect with the homeowner. They did much more than clean a war zone. They gave someone hope again where there was very little. Thank you. Truly.

Amanda and Megan's support during this unfortunate event has been invaluable to our family, and we appreciate their dedication from start to finish. Corey and the entire team consistently displayed compassion, expertise, and care. Your company's philosophy, 'help first, business second,' resonates deeply and is clearly reflected in your work. Thank you.

Amanda graduated from Forest Park Community College with two degrees relating to business/management and Megan graduated from Lindenwood University with a bachelors degree in Criminal Justice. After they both served several years in law enforcement within the St. Louis County area, Amanda and Megan decided to start a new chapter in their lives by opening a Bio-One franchise.

    My company has used Bio-One STC many times for clean ups. They respond quickly, and every employee I have dealt with has been professional, caring, compassionate, and friendly. I would highly recommend Bio-One STC for any job you may need. They provide compassion in difficult times for families, so I have recommended them to others needing help. Not only do the owners, Megan and Amanda truly care about people who are experiencing a crisis, but they also give back to the community as well. Bio-One STC is there for you when you don't know where to turn in a difficult, emotional situation.
