Bio-One of Denver biohazard and decontamination Company Owner, Gregg and Cheryl Chiasson

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.

The company was professional and less expensive than the other ones who provided an estimate. I also found the owner very easy to work with.

Bio-One helped my clients on short notice right before Christmas. They were very helpful, quick to act, and did the job right so my clients could close on their sale and move on. I recommend them for anyone needing a quick, but thorough clean up.

My call was returned quickly, Gregg explained how this works, I wasn't real happy with evaluation after Justin returning and telling me it was a 1 on a scale 1-10 but Justin was on time, very professional and communication was excellent. Made sure I was satisfied before leaving. Only wished I would have gotten before and after photos since I'm not one to go into my crawlspace. At this time I am very pleased.
