A Board-Certified Doctor Practicing
Functional Medicine in Mid-Michigan
Dr. Janet Eng combines more than three decades of board-certified emergency medicine with the most advanced regenerative therapies available — serving patients in Okemos, East Lansing, Lansing, MI, and across the wider Mid-Michigan area.
Dr. Janet Eng, D.O.
Dr. Janet Eng spent more than thirty years as a board-certified emergency physician, treating critical patients on some of medicine's hardest days. Fellowship-trained in medical toxicology, she became deeply familiar with how exposure, deficiency, and accumulated stress shape the human body over a lifetime.
That clinical experience led her to a different question — how do we keep people out of the emergency room in the first place? In time, she moved into functional and regenerative medicine: an approach that asks why a problem began, not just how to manage its symptoms.
Affiliations & Verified Coursework
A lifelong learner, Dr. Eng has pursued continued training through the University of South Florida | Morsani College of Medicine Personalized Medicine Course, American Academy of Anti-Aging Medicine (A4M), Age Management Medicine Group (AMMG), the Institute for Functional Medicine (IFM), Frequency Specific Microcurrent, and My Injection Training. She is also currently participating in the AMSKU Ultrasound Fellowship, further expanding her expertise in image-guided therapies. Her approach integrates energetic, functional, and personalized medicine, allowing her to tailor care strategies that strengthen and rejuvenate the body rather than simply treating disease.
Her clinical interests focus on whole-person wellness across every stage of life, sports medicine and recovery, and bioenergetics — the science of how cells produce, store, and use energy. She believes the body is built to heal itself when it has the right inputs and the right environment, and that even the most advanced therapy works best when the foundation underneath it is sound.
Think of it this way: even the finest fuel in the world cannot make a damaged engine run properly. The same is true of your body. Before layering in therapies and supplements, Dr. Eng works with you to find and address what is actually slowing you down — so every intervention you receive afterward has the chance to do its real work.
She practices personally and unhurriedly. Every patient is evaluated, treated, and refined directly by her — never handed off to a rotating staff.

How We Work Together
We start with a detailed conversation, a comprehensive intake, and the lab and imaging work it takes to understand what is actually happening in your body.
Dr. Eng builds a personalized protocol — drawing on functional medicine, regenerative therapies, IV nutrition, and the clinic's full toolkit — designed around your goals and your life.
We use objective measures — labs, body composition, resting metabolic rate, and how you feel day to day — so progress is something we can see, not guess at.
Every plan evolves. As your body responds, we adjust the protocol so it keeps moving you forward through every season of life.
