The business does a great job and Kevin is on top of things
Matt Large
I highly recommend Kevin and the Bio-One team. Their dedication and commitment to supporting their customers is exceptional. I truly appreciated their communication and updates throughout the process. You can rest assured they will get the job done right the first time.
Daphne McIntyre
I used Bio-One for a hoard clean-up that I assisted with. I cannot recommend Kevin and his team highly enough. He has been so professional, thorough, and incredible to work with. His communication is outstanding. He went above and beyond anything I was expecting and I can't appreciate it enough. Kevin was communicative before, during, and after the cleaning process. He explained the full process of the clean-up and removal and then follow-up steps. I would hire him again, in a heartbeat, for any big job that requires a true professional.

    I've known Kevin for more than a decade and worked with Kevin on a variety of non-profit activities for the past five years. Kevin has drive and a commitment to excellence in everything that he does. What impresses me most is his ability to work across generations and personality types to gain consensus on challenging issues, and then drive to a positive resolution. He always seems to have the end result front and center in his thinking. This helps him see past potential roadblocks and drive to the desired outcome. He's organized, methodical in his approach, and detail oriented. Best of all, Kevin is simply a great person. Someone you genuinely like to be around because he makes you feel important, and puts your welfare equal to his own. In client service, I can think of no better characteristic.
