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!

Bio-One helped us deal with a very difficult situation. With one phone call that was answered immediately, I was able to schedule Bio-One’s services. They arrived on time and the clean up was thorough and respectful . Bio-One filed a claim with the insurance sobI had one less thing to worry about. I recommend them highly. Professional and so kind!!!!!

    Gregg and Cheryl Chiasson
    Owner
    Gregg and Cheryl Chiasson are active, experienced business owners in the Denver area. They find fulfillment serving the community, providing jobs, and supporting non-profit organizations. Owning a Bio-One franchise is a natural fit to their values and mission of service to others. They hire team members who share these values, a key element in helping families experiencing a tragedy. Their son Sean, an outdoor enthusiast, resides in Bend, Oregon where he works as an accountant at a vineyard as well as a climbing and adventure guide. Their son Kyle, also an entrepreneur, lives in Denver and owns a successful water damage restoration business (Best Option Restoration). Gregg, having served in the ambulance industry for 30 years, is experienced in emergency response and understands the needs of a family experiencing a trauma. He spends his spare time mentoring youth and supporting several non-profits. Cheryl's career in hospital marketing also gives her insight to the needs of a family in crisis. She finds joy in helping others both personally and professionally. Cheryl excels at listening to people, recognizing their needs, and finding ways to meet those needs.

    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.

    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!

    It's comforting to know a company like Bio-One exists in Denver. I hope I never need to use them as they specialize in crime scene cleanup. Their motto is help first and business second. They are heavily involved with the Sheriffs offices of CO and will be available in a time of need.

    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! :)
