Mike DeCapua
The team was so professional, understanding to our needs and respectful. No matter what was going with our cleanup, they understood what was needed and was able to get the job done.
Steve R
BioOne and TJ were extraordinarily compassionate, helpful and responsive during a very stressful time. TJ in particular displayed great empathy and insight. It's so clear that this team has seen it all, but they're focused on more than getting the job done thoroughly -- they prioritize human dignity, a detail that's often overlooked yet absolutely invaluable.

    Jake PC, Lake County, 06/2025
    I can’t speak highly enough about the team at Bio-One Chicago. TJ and Monty, the owners, were incredibly professional, responsive, and compassionate throughout the entire process. Following a biohazard situation, they arrived promptly, handled everything with precision and care, and most importantly, treated the situation — and my family — with deep respect. Their coordination with my insurance company was seamless, which took a huge burden off my shoulders. They kept me informed, ensured everything was documented properly, and truly went above and beyond. If you’re looking for a team you can trust during a tough time, Bio-One Chicago is the one to call.
