At BG Medical Center, we are proud to welcome our newest physician Dr. Pratumngern, a Doctor of Osteopathic Medicine with more than 25 years of experience in Family Medicine, Occupational Medicine, and Medical Toxicology. She brings a unique whole-person approach to care — combining deep clinical expertise with a strong focus on prevention, longevity, and optimizing overall wellbeing. We sat down with her to learn more about her journey and philosophy of care.
Many patients still ask, “What is Osteopathic Medicine?”
How would you explain it in simple terms? Osteopathic Medicine is a distinct branch of medicine that focuses on treating the whole person — not just symptoms. It recognizes that the body, mind, spirit, lifestyle, and environmental factors all play a role in a person’s health. The core philosophy is that structure and function are interconnected, and the body has an innate ability to heal itself when conditions are optimal. As osteopathic physicians, we look beyond isolated problems and work to support overall balance and long-term wellness.
What is the difference between a DO and an MD?
Osteopathic physicians (DOs) are fully licensed physicians in all 50 states. We prescribe medications, perform procedures, and practice in all medical specialties — including surgery. The difference lies in our training and philosophy. DOs receive additional training in holistic care and the musculoskeletal system, and we emphasize preventive medicine, primary care, and optimizing the body’s natural healing capacity.
What inspired you to pursue Osteopathic Medicine?
I grew up watching my grandfather, who was a traditional Chinese medicine doctor, whose clinical and diagnostic skills were exceptional. He cared for everyone in our community, and the respect and trust his patients had for him deeply inspired me to become a physician. Years later, during medical school, I had the privilege of training with Dr. Joseph Matheu, an Osteopathic family medicine physician. His rapport with patients and his holistic approach reminded me of my grandfather. That experience confirmed my calling and strengthened my commitment to Osteopathic Medicine.
You have been practicing medicine for over 25 years. Can you share your professional journey?
I began my academic path at Loyola University Chicago, where I earned my Bachelor’s degree in Biochemistry. I then attended Midwestern University and received my Doctor of Osteopathic Medicine degree. I completed my Family Medicine residency at St. Francis Hospital of Evanston and am proudly board certified in Family Medicine. Throughout my career, I have practiced not only Family Medicine, but also specialized in Occupational Medicine and the treatment of work-related injuries. I am also board certified in Medical Toxicology. These diverse areas of practice have allowed me to develop a broad and comprehensive understanding of health, disease, environmental exposures, and complex medical conditions. You have a special interest in anti-aging and optimizing wellbeing.
What does “true health” mean to you?
I truly believe that true wealth is having good health. To me, health is more than the absence of pain or disease. It is about optimizing how the body functions, supporting longevity, preventing illness, and helping patients feel their best physically and mentally. My goal is to guide patients toward their optimal wellbeing at every stage of life.
What can patients expect when they come to see you?
When patients come to see me, they can expect to be respected and listened to. They are encouraged to participate in shared decision-making. My responsibility is to inform and educate my patients using the latest medical advancements. Together, we become lifelong partners in the pursuit of health and optimal wellbeing.
