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.

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 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 was there for us with every step of the way during cleanup after the death of a family member. The team was responsive, empathetic, organized, efficient, helpful and thorough. Highly recommended for biohazard remediation, deep cleaning, trash removal and overall helpfulness should you be in a position to need their services.

    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 disinfectd 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.
