GeminiBio provides serum, customized media, buffers, and process liquids to biopharma and advanced therapy companies focused on the research and production of mRNA, AAV, monoclonal antibody, and cell therapy technologies.

Mike Stella is the CEO of Ascend Advanced Therapies, a contract development and manufacturer (CDMO) of Adeno-Associated Virus (AAV) gene therapy products headquartered in Rockville, Maryland. Mike has over 20 years of business and operations leadership experiences in the manufacturing of cell and gene therapies. Prior to joining Ascend, he spent over 15 years at Cognate Bioservices, a cell and gene therapy CDMO, where he held executive leadership roles in operations, first as the EVP of Global Operations and for the last 7 years as the company’s Chief Operating Officer (COO).

Mike joins the Board at GeminiBio, which includes:

• Executive Chairman of the Board, Cory Stevenson: Mr. Stevenson served as the President of the BioProduction Division of Thermo Fisher Scientific (NYSE: TMO), a world leader in serving the biopharma sector, with annual revenue of more than $40 billion. During Cory’s tenure, the BioProduction business grew from $200 million in revenues to over $2.5 billion annually.

Prior to joining CLS, Mike held executive leadership roles in sales and business development at VWR, part of Avantor for 14 years, including as the VP of Sales for the last 4 years of his time.

Prior to creating PTSI, Mr. Sandoval served as the Facilities and Engineering Director at Amgen (NASDAQ: AMGN) for 20 years. In that role, Steve was responsible for leading teams in support of Amgen’s global facility expansion initiatives – including the Puerto Rico site. Steve held various facilities and engineering leadership roles that included building a site from concept to completion within 2 years, building engineering programs, and developing a reliability-centered maintenance program. He has a depth of experiences in the areas of manufacturing, engineering, process development, supply chain, commissioning, validation and quality. Mr. Sandoval joined the Board in Jan 2024 and continues to provide invaluable insights on how to partner with organizations in the early facility design phases to provide media and buffer hydration services.

Mr. Stober joined the Board in Jan 2025 and will be instrumental in providing insights related to raw material supply needs of biologics manufacturers and CDMOs.

“As a long-time operations executive in cell therapy development and manufacturing, I recognize the critical role that GeminiBio plays in the supply chain. The company is ideally suited to address the challenges of customers (large and small) that need quick turnaround buffer and media hydration solutions. These solutions are often critical to the process but not the science of these therapies. By leveraging GeminiBio’s solutions, companies can avoid costly investments in equipment, facilities and personnel while shortening the time to market with the life-saving treatments patients need today. I am looking forward to offering my industry and operational insights in support of GeminiBio’s continued growth and development,” said Mike Stella.

Cory Stevenson, Executive Chairman of the Board, had this to say: “I’ve worked closely with GeminiBio’s CEO, Brian Parker, these past few years to assemble a diverse and experienced board that will provide the company with improved insights to customers and their needs as innovators and CDMOs within the biopharma and advanced therapies markets. With the addition of Mike Stella to our board, we will gain access to decades of invaluable insights in the development, manufacturing and operational processes of our cell and gene therapy customers. These deep insights will allow us to continue to align our media and buffer solutions to better meet the needs of our customers.”

The addition of Mike Stella to the Board provides GeminiBio with a robust group of leaders experienced in several key market sectors including cell and gene therapy, biopharmaceutical manufacturing, contract manufacturing and development, and distribution channels. Additionally, the knowledge of this Board covers key areas including policy, regulatory, manufacturing and facility design, raw materials performance requirements that fuel manufacturing process efficiencies and customer buying behaviors – all of which will be instrumental in helping to shape the strategic direction of the company as it continues to deliver commercial excellence.
