Owner
Amanda Boccardi is one of the owners of Bio-One of St. Charles, along with Megan Boccardi - Amanda and Megan, both grew up in St. Louis area. 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. After hearing about how Bio-One helps families and people during very difficult times, both Amanda and Megan jumped at the opportunity to open Bio-One of St. Charles and continue their passion for helping those who need it the most. With the opportunity available to continue to be involved in the community and help others, it was an obvious decision for Amanda and Megan to be a part of the Bio-One family.

I would highly recommend Bio-One STC for any job you may need. I have known the owners for over 10 years now and they are some of the most loyal, caring, and hard working people I have ever met. On top of the great work they do, they are involved and support the communities they service. If you are looking for personal service with professionalism, Megan and Amanda will undoubtably give it to you. So many times to companies you are just a bid or a paycheck, but not with this company. Megan and Amanda will truly be able to make a horrible situation that someone may be in, just that much better.
