Jade Welegala

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 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!

After my parents passed, I really needed help dealing with the situation at my parent's house. It was not a one-person job.

Bio-One was incredibly 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.

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 Jena) 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.
