    Bio-One of San Jose owner, Desmond Tai
    Desmond Tai
    My name is Desmond, I’m a certified Mental Health First Aider and First Responder. I left the healthcare industry and became the proud owner of Bio-One of San Jose. After I finished graduate school, I worked in the healthcare industry for over 20 years. During the last 4 years and since the pandemic, I have successfully hosted many clinics—from COVID-19 to flu—at different organizations, including long term care facilities, government agencies, and businesses. I’ve had the privilege in my profession to have been able to touch many people's lives, especially at the beginning of the pandemic. I have seen how these clinics have had a positive impact on many people. The vaccines administered enabled many patients to see their family and provided relief to parents who want their children vaccinated. I left the healthcare industry for the biohazard cleaning industry with one goal in mind: to continue to provide direct impact services to my community. My passion in helping others did not stop after leaving the healthcare industry, but continued in a different way. I help my clients by helping them to reorganize their living spaces, helping them to see a light at the end of the tunnel, providing them with a fresh or new start, cleaning up trauma scenes, and minimizing reliving the trauma they went through. I believe in helping first and business second. With that, I joined the Bio-One team. Bio-One provided me with the necessary training and the tools to help our common clients. At the same time, it provides me opportunities to support my passion in helping the members of my community. Bio-One of San Jose prides itself with serving our communities by making crime scene, trauma and hoarding cleanup respectful and efficient. With compassion, diligence and professionalism, Bio-One of San Jose is ready 24/7 to help community members who are in their greatest time of need. Call us for immediate response in and around San Jose. We service Santa Cruz, Monterey, Fresno and surrounding areas. I can be reached via email at or contact me at (408) 309-3866.
