I’m Eric Pifer, MD, founder of LifeLab Concierge Medicine.

​

I trained in internal medicine at Temple University Hospital, where I later served as Chief Resident, after earning my medical degree from the Medical College of Pennsylvania. I went on to serve as an Assistant Professor of Medicine and Clinical Instructor at the University of Pennsylvania, before holding Chief Medical Officer roles in several California health systems.
 

In 2022, I founded and built a major concierge medicine program in San Francisco. That experience reinforced something I had come to believe over many years in medicine: the best care happens when the physician has the time, tools, and relationship needed to understand the whole patient.

​

In 2025, I wrote The LifeLab Protocol, a practical one-year pathway focused on metabolism, sleep, glucose control, fasting, fitness, and long-term health. In 2026, I launched LifeLab Concierge Medicine to bring that philosophy into a smaller, more personal practice.

​

LifeLab is built for patients who want more than a standard annual physical. It combines concierge medicine, advanced metabolic testing, and an affordable weight loss program directed by me personally. The goal is to help patients understand where they are, what needs to change, and how to improve their health over time.

​

At its core, LifeLab reflects my belief that metabolism is central to healthy aging, and that excellent medical care should be personal, measurable, and deeply human
