Testimonials



Our first experience with VTI was fantastic. Kai was super nice and helpful during this stressful process. I can’t describe how happy and satisfied we are with his work and all of the protocols he made for us. Our Ex FDA Consultant reviewed each one individually and she was amazed by  his work and the protocols. She told me that everything looks perfect and the protocols are very organized and clear to understand. He was very detail oriented and he went above and beyond on this project. We are so happy to have this cooperation with VTI and looking forward to working with you in future as well.

Very knowledgeable, easy to work with.  Planned ahead.  Dealt with deviations and change controls very well.

David Vincent and the VTI team of validation engineers did an excellent job validating a new 100,000 square foot classified biologics manufacturing facility for us in California. Planning, execution, costs and timeliness were all best in class. VTI is my first choice for facility, utility, and equipment validation.

I just want to let you know how pleased I am with your team’s performance thus far.  They have truly taken a lead role, working well with the Cleaning Development staff and controlling daily operations as expected.  Effective communicators, politically savvy and in general a pleasure to work with.
