About Dr. Stengler & The Stengler Center

Mark Stengler

Dr. Mark Stengler “America’s Natural Doctor®.”

Like you, Dr. Mark Stengler was once looking for an alternative. Even before he became a celebrated integrative physician he knew there was something critically wrong with the conventional medicine approach to treating illness. But it was after watching a loved one fall victim to that broken system that he finally realized that what’s actually missing from the mainstream drugs-and-surgeries approach is a massive lack of balance. He also realized that his true calling was in medicine as a Naturopathic Doctor.

Dr. Stengler’s not your typical doctor. Not by a longshot. He stands out in a crowd, because, unlike most conventional doctors, his carefully constructed medical training was all about balance. He received extensive training in both conventional medicine and natural alternatives.

What this fusion means for you, of course, is that when you make an appointment with this Naturopathic Doctor in San Diego you’re getting the perfect combination of advanced modern technology and powerful time-tested traditional therapies. This balanced approach means you get the very best medical care, and the safest long-term treatments, available.

And Dr. Stengler’s got a 20-year track-record of successes to prove how well his radical approach works. In fact, his breakthrough methods have earned him national attention and acclaim as “America’s Natural Doctor®.”

He has been asked to be a medical expert on FOX, CBS, and NBC, and he hosts his own popular weekly TV show “Natural Healing with Mark Stengler,” which can be seen on PBS and cable stations all across the nation. He’s been involved in two PBS documentaries on natural medicine: “7 Steps to Perfect Health” and “Supercharge Your Immune System,” and he will serve as the host of an upcoming PBS educational and fundraising show on natural health.

Dr. Stengler lives in San Diego County, California with his wife and three children. He finds that sunny San Diego is the perfect location for him to pursue his active lifestyle, playing his favorite sports and running around with his kids. Dr. Stengler regularly speaks on natural health topics and pursues a number of hobbies, including theological studies.

When he’s not busy sharing his extensive knowledge of powerful alternatives to toxic “mainstream” therapies, Dr. Stengler practices what he preaches at his state-of-the-art Stengler Center for Integrative Medicine in Encinitas, California.

“Those that know do. Those that understand teach.”

Besides practicing what he preaches at his clinic in California, Dr. Stengler also teaches what he preaches. He served as an associate clinical professor at the National College of Naturopathic Medicine in Portland, Oregon, and has served on a medical advisory committee for the Yale University Complementary Medicine Outcomes Research Project.

“Either write something worth reading or do something worth writing.”

In addition to his clinical and academic work, Dr. Stengler manages to write House Calls—a several day a week e-letter—and Health Revelations—a once a month newsletter—that currently reach over 400,000 regular readers combined ( He subscribes to the notion that if there’s a book that you want to read that hasn’t been written yet, than you need to write it. As a result, he’s authored/co-authored 30 books including three best sellers, The Natural Physician’s Healing Therapies,” “Prescription for Natural Cures,” and “Prescription for Drug Alternatives.”

“Education is the most powerful weapon.”

Mark Stengler, N.M.D., completed his premedical studies at Mt. Royal College (in Calgary, Alberta, Canada), and the University of Calgary, and graduate-level naturopathic medical school at the National College of Natural Medicine in Portland, Oregon.

His naturopathic medical education taught Dr. Stengler the same basic sciences studied by MD candidates, but it also provided him with an equally as extensive knowledge of holistic and nontoxic methods. This balanced approach put a strong emphasis on disease prevention and optimizing wellness.

In addition to a standard medical curriculum that included training in diagnosis, lab testing, pharmacology and minor surgery, Dr. Stengler’s well-rounded education also had him complete training in bio-identical hormones, intravenous nutrient therapy, chelation therapy, ozone therapy, clinical nutrition, Chinese medicine, homeopathic medicine, botanical medicine, psychology and counseling to encourage people to make lifestyle changes in support of their personal health.
