The owners, Megan and Amanda, are wonderful! From the first phone call to the end of service, they made our horrible situation so much easier and their team was so nice and easy to work with. I don’t know how anyone could complain about this company and their work, especially nowaways when it’s hard to get a company to even come and do work. I highly recommend this company! You will not be disappointed!

The loss of my Dad was hard enough. I had no idea what to do about the unfortunate cleanup. Called Bio-One and they showed up the next day. On time and very professional. Even got me through the homeowner insurance process. I highly recommend them and would definitely use them again. Thank you sincerely!!!!

Thank you to Corey and Antonio for coming out and cleaning my rental. As well as getting all the photos, measurements and handling all the insurance stuff. Megan did amazing with the office part of everything. I appreciate all of you more than I can express. It definitely helped during the process of grief. I'll keep praying over all of you as you continue to help others in the worse of their lives.

    I contacted Bio-One on a Saturday, due to finding my grandfather deceased & Bio-One was on site the next day. Bio-One was so amazing to work with. They were gentle during a hard time & did an amazing job on top of it. Megan, one of the owners, was absolutely amazing! She was responsive & able to answer all of my questions & help along the way. Thank you guys for taking such a large load off of my plate!

    It took me years to get the courage to call someone for help. After my young son passed away I became depressed and my home became a time capsule. I could not get rid of anything because there was a memory attached to everything. I became a hoarder. When I finally took that first step, I spoke with Amanda. She was very kind and reassuring. But my anxiety kicked in and I didn't call them back to schedule anything. Almost a year later I reached out again, Amanda did not question or judge me for not calling her back. She was patient and understanding. The big day came... Hali and her team (Antonio, Corey, and Jenna) were awesome!! Hali made me feel comfortable from the moment she walked in. She was so respectful and made the whole experience bearable. A few times I started to get overwhelmed, but Hali was compassionate and patient. The whole team were very professional and personable. They also went above and beyond, hanging paintings and mirrors. And thanks to Corey my toilet finally flushes properly. My hoarding was embarrassing and overwhelming, but Amanda and Megan are wonderful, and they have a great team that changed my life.
