Pros
The culture can't be beat- it's embraced by nearly every employee. The products are best-in-market and getting better. Top-notch science and experience- such that even Roche's pharma competitors are in long lines to sign contracts with Ventana for companion diagnostic work.
Cons
The Roche acquisition changed the color of things at Ventana; we're not a scrappy start-up anymore. We went from biggest fish in a small pond (something to hang your hat on) to tiny fish in a big ocean ($500m revenue is a drop in the bucket to Roche Dia's billions). Still vital, and absolutely crucial to Roche's diagnostics portfolio, however. Many people are seeing the recent consolidation of commercial operations to Indianapolis as a death knell; those people don't realize that Ventana is more than US commercial operations. Sorry to see friends go, but it's optimizing operations and freeing up space for Development, Manufacturing, Marketing and other global organizations to grow. Many of those leaving already have jobs in Indy, so net job loss is minimal.
