What our clients say
Laurie Yee, Buena Park, 02/2025
Cory of Bio-One ot Orange was so compassionate and helpful - I felt comfortable from the first conversation and later with the team of four men who came to do the job. Nobody was judgemental of me. They were very discreet as i requested. I am so glad they came to help me with my home!! They were SO competent and thorough and detail-oriented! They followed my suggestions as I made them. They did a great job of asking what I wanted to throw away. They did much on their own, they cleaned what I didn't even think of them to clean - what great surprises! Each of the team members were so polite and helpful and hard-working. Each of them had wonderful attitudes! It was easy for me to talk with them. After I told them what I wanted done, they often were able to be self-directed. I totally am happy to refer them to people needing any size job done, I was so impressed with everyone and everything!! Thank you for a great experience!!

Had a wonderful experience with Bio-One. Cory the owner is top-notch and a consistent communicator. The crew was great as well, bringing a collaborative approach, a ton of hard work and absolutely no judgment. Would highly recommend Bio-One and will be using them as similar projects arise in the future.
Chelsea, Westminster, 11/2024
I've worked with Bio-One twice; once to clean out the home of my uncle, who hoarded items + animals, and another to help clear out my mom's garage! It took a while to convince my mom her garage needed some help; but I managed to persuade her because of how how impressed we were with Bio-One the first time. Cory made coordinating really easy. Big shout out to David R. & the team! They were patient, sensitive and accommodating - my mom for sure loved them. She's been so thrilled now that it's cleaned out; it's made a huge difference and we were able to find some papers and photos that had been missing for ages. I highly recommend them, especially if you have immigrant parents who have a hard time letting go of things!
