Jeff Yuen, a speaker respected both domestically and internationally, dedicated over three decades to the world of regulatory compliance and quality systems before he founded his consulting firm. Known for his expertise in CGMP (Current Good Manufacturing Practice) and compliance, he has gained recognition, particularly in sterile drug manufacturing, biotech product inspection, aseptic filling, quality systems, and process validation.

While serving as a peace officer/investigator and later as a Consumer Safety Officer for the US FDA, Jeff grasped the critical nature of “right first time” practices. He witnessed the impact of thorough regulatory inspections on the pharmaceutical, biologics, biotech, and diagnostics industries. He saw the complexities of FDA regulations and identified the need for expertise in navigating these intricate regulations in the industry.

Jeff understood that companies needed to prepare for critical inspections and embrace operational excellence and performance improvement as catalysts for organizational and cultural change to flourish.

Motivated to make a difference, Jeff founded Jeff Yuen & Associates, Inc. in 1998 after leaving the FDA. His firm combines the expertise of former FDA national experts, industry specialists, and scientific professionals, providing comprehensive support for pharmaceutical quality throughout all product development and commercialization phases.

Under Jeff’s leadership, the firm has become a champion of the “right first time” philosophy, advocating for thorough root cause investigations and the implementation of meaningful Corrective and Preventive Actions (CAPA). His passion for mentoring and teaching has left a positive impact on numerous companies, equipping them with the tools for success in an era of rapid technological progress and stringent compliance standards.

A Journey from Passion to Profession

Jeff Yuen earned a BS in Biological Sciences from the University of California, Irvine (UCI), a Masters in Public Health from UCLA, and an MBA from National University. He served as the President of the PDA – Southern California Chapter and as a Board Member for the Institute of Validation Technology’s Journal of CGMP Compliance. UCI honored him as a “Distinguished Alumni for the School of Biological Sciences.”

From a young age, Jeff had a deep-rooted passion for medicine and public health, ignited by his surgeon father whom he accompanied during hospital rounds. As a teenager, he aspired to follow in his father’s footsteps.

However, despite 38 attempts, Jeff was not accepted into medical school. Instead, he gained admission into a public health program on his first attempt. As a devout Christian, Jeff saw this as a sign that God had a different path for him. He believed that God intentionally closed the door to medical school to open another one for him in public health.

This new path led Jeff to various roles in government service, health departments, and the FDA. These experiences eventually culminated in the creation of Jeff Yuen & Associates, Inc. (JYA).

Even before conceptualizing JYA, Jeff desired to make a difference and give back to society and the world. He often joked about his work compared to his father’s, saying “He had his patients, but I had the world, serving communities and countries.” 

Jeff believes global citizens have much to do, whether ensuring access to healing for those in need or preserving the planet’s natural wonders. After his father’s passing, Jeff reflected on his life and future direction. For him, it’s all about giving back, and he is committed to doing his part.

They refuse assignments where they cannot bring the proper subject matter experts to the client, emphasizing their commitment to quality and expertise.

The Team behind JYA: A Fusion of Expertise and Experience

What sets JYA apart is its uniquely composed team. It’s a balanced blend of former regulators and industry experts who serve the pharma, biotech, and medical device industries.

A Leader Defined by Achievements and Recognition

During his tenure with the US FDA, Jeff quickly ascended to the rank of Commander in the US Public Health Service. He served on several teams, including the FDA’s Pacific Regional Biotech Team, the Foreign Inspection Cadre, and as the Los Angeles District’s Drug Team Leader and Pre-Approval Manager. In these roles, he specialized in high-priority drug (PAI) and biologics (ELA and BLA) inspections.

The US Public Health Service awarded Jeff numerous commendations and achievement medals for his work. Notably, Vice President Al Gore’s Office presented him with the “Hammer Award” for his leadership and participation in innovative biotechnology/FDA industry outreach programs.

In addition to his work at JYA, Jeff actively participates in several executive advisory boards. He continues to serve on BIOCOM’s FDA Committee, UCI’s Biotechnology Advisory Board, and UCI Extension Advisory Board. He also continues to teach at PDA-TRI.

His active involvement in these roles highlights his commitment to the industry and his eagerness to share his expertise.

“Long before JYA existed, God placed a burning passion and humble desire in me to make a difference and to give back to society and the world. There remains much for all of us to do as citizens of the world, whether that be working to ensure that spiritual, emotional, and physical healing is made accessible to those who are deprived or preserving the natural wonders of this planet.”
