503B GMP consulting

GMP consulting for 503B outsourcing facilities

From site build-out to trained operators.

We work with founders standing up their first sterile compounding facility and with established manufacturers expanding capacity or correcting course after an inspection. The work covers regulatory strategy, product selection, site design and GMP build-out, quality systems, and the SOPs and operator training your facility runs on once the doors open. The expensive mistakes happen early. We help you make those calls, then stay involved while they get executed.

I run a consulting practice for 503B outsourcing facilities and I am finishing a PhD at Purdue studying peptide drug delivery.

Before starting the practice, I was the founding employee at ProRx, a 503B outsourcing facility, where I helped bring sterile manufacturing online, build out the facility and bring in new clients.
