Leadership and Senior Consultants

The leadership of BioTechLogic is comprised of three former Searle/Pharmacia/Pfizer BioPharma colleagues: Peter Dellva, Patrick Giljum and Tracy TreDenick

The Biopharma group that these founders supported was responsible for the management of a virtual supply chain that assures biopharmaceutical supplies, managed third-party contract manufacturers, negotiated contracts, and provided technical and submission support to develop the manufacturing and regulatory documents that would support global drug submission and approval.

When Pfizer closed the former Seale Chicago Site in 2003, these colleagues saw an opportunity to provide a valuable service. Many of BioTechLogic’s employees share this same history.

Collectively, they offer more than 50 years of experience in the biopharmaceutical industry—and they lead a staff of experienced experts in the field. They work as a team to help clients overcome regulatory and submission hurdles and achieve commercialization success.
