We follow state guidelines for safe removal and disposal of our regularly scheduled medical waste pickups. Weekly, monthly, and quarterly transportation is offered from facilities such as:

Most helpful and thoughtful company! I called to ask for an estimate on getting a meth test done on my recovered stolen vehicle and the owners were so knowledgeable and kind! They gave me advice on the steps to take before getting the test done as to not waste my time or money on the testing. They were so compassionate and caring! HIGHLY RECOMMEND THIS COMPANY! :)

Bio-One was an incredible company that I found under extremely unfortunate circumstances. They cleaned up after a very traumatic unattended d3ath and addressed it with professionalism and compassion, which was greatly needed after losing a parent. While I hope I never HAVE to use them again, I absolutely would in a heartbeat.

Bio-One made a very difficult situation much easier. A relative had a communicable disease and passed away in the house but was not discovered for some days. Bio-One not only cleaned and sanitized all surfaces but also removed carpeting. Since hoarding was a problem, they helped with saving documents and valuables and disposing of the rest. Their charges were reasonable and they helped with the insurance. They solved in a few days a problem that would have take my family weeks deal with.

The team helped my family member tame two years of long-Covid clutter in two days. From our first contact with Gregg to the end of the process, we were treated with dignity and understanding. Our only regret is that we didn't call sooner!

Gregg and the cleanup team assigned were kind, considerate, and efficient. A relative had died and had not been discovered for several days. We appreciated the timely response and efficient removal of contaminated materials. Their approach made a terrible situation as quick and simple as possible.

From the get go when Greg came out to look at moms house he was very professional and compassionate. The day the job started everyone in the team worked hard, followed direction, even made time to listen to moms stories which made it easier on her to let things go. Overall the team was amazing and did a wonderful job exceeding all our expectations. Definitely recommend highly.

We are renting a house that was previously occupied by hoarders, so I contacted Gregg and his team at Bio-One to come out and look at the property. To my delight and surprise, Gregg was open and honest and let us know that his services were probably not going to be the most cost efficient for our needs - he recommended another cleaner and was honest about saving us hundreds, if not thousands, of dollars. While I didn't use Bio-One's services, I would recommend them 100 times over for their excellent customer service and best business practices!
