Core service pillars
Our principals

Direct technical involvement, every engagement.

Our principals lead the work themselves. Together they bring deep combined cGMP experience across upstream and downstream processing, monoclonal antibody manufacturing, plasma protein extraction, MSAT and bioreactor engineering, and quality systems operations.

John T. Davis, President and Founding Principal
John T. Davis
President & Founding Principal

John founded the practice in 2011 after three decades operating in the bioprocess industry. His nearly forty years of work spans large molecule fermentation and cell culture, protein and nucleic acid purification, human plasma protein extraction by Cohn fractionation, vaccine manufacturing, and emerging cell and gene therapy modalities. Earlier roles include Sutro Biopharma, Cytovance Biologics, and FUJIFILM Diosynth Biotechnologies. He holds a degree in Biology from American University.

Luis Mejia, Vice President
Luis Mejia, M.S.
Vice President

Luis joined the firm in 2020 and brings over two decades of biotechnology and biopharmaceutical experience. His technical depth covers upstream and downstream processing, with particular focus on monoclonal antibody cell culture and purification. Luis is grounded in the principle that quality extends beyond technical rationale into the safety and care owed to the patients and communities biologics serve. He holds a Master of Science from West Chester University of Pennsylvania.
