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 helped us tremendously with a tough situation. From the initial phone call with Gregg, to meeting with Kevin and Elvis, everyone was helpful and caring. It's amazing to me how much they were able to do to help us - from removing carpeting, treating the home with the right chemicals, dealing with the insurance company and assisting in clearing contents. The entire team really know what they're doing and are very competent and efficient. I highly recommend them and can vouch for their integrity.

Sarah Kinn, Denver, 05/2025
The owners of Bio-One Denver were available, communicative, and helpful right off the bat. They took the time to walk me through their process of cleaning my vehicle, billing through insurance, etc. This a quality company with great people running it. I can't say enough. Had a really positive experience with them.

We had Justin, Joel and Sarah come out to help us get three sheds with serious mouse infestations all cleaned out. They did an excellent job in a timely manner and were tremendously friendly and professional. Would definitely hire them again!
