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.
