It took me years to get the courage to call someone for help. After my youn... g 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.   Read more >

    Max Metzger, Lincoln County, 04/2024
    After my parents passed, I really needed help dealing with the situation at my parents' house. It was not a one-person job. Bio-One was inc... redibly helpful. They didn't just help with cleaning and trash removal, they were also amazing at sorting through everything so that I could find and keep the valuables and sentimentally important heirlooms that were mixed in with everything else. The crew was always phenomenal. They were professional, fast working, and genuinely fun to be around. Bio-One understands that it's not just a cleaning job, there's an emotional component as well. I cannot recommend them highly enough.  Read more >
