In today’s complex healthcare landscape, more individuals and families in Rancho Santa Fe are seeking a better way to manage their health — one that moves beyond temporary fixes and gets to the root cause of illness. That’s where complementary medicine comes in: a modern, holistic approach that blends the best of conventional care with evidence-based natural therapies to restore balance, enhance vitality, and promote long-term wellness.
Known for its wellness-conscious and high-performing residents, Rancho Santa Fe is a community that values quality, proactive health solutions. Whether it’s hormonal imbalance, chronic fatigue, digestive dysfunction, or simply the desire to age well and stay sharp, locals are turning to providers who offer personalized, preventive, and natural care — not just prescriptions and procedures.
At the Stengler Center for Integrative Medicine, Dr. Mark Stengler, NMD, delivers a care model that’s as unique as it is effective. As a nationally recognized integrative physician, Dr. Stengler combines advanced diagnostics and scientific precision with Christian compassion and individualized attention. Each patient receives a tailored plan designed to support their body’s God-given ability to heal — physically, emotionally, and spiritually.
From busy executives to health-minded families, Rancho Santa Fe patients appreciate Dr. Stengler and his team's ability to deliver targeted, whole-person treatments that respect both modern medicine and natural healing wisdom. If you're seeking more than a quick fix — if you're looking for clarity, balance, and long-term health — the Stengler Center is here to guide your journey.
Complementary medicine refers to the use of natural, evidence-based therapies alongside conventional medical treatments to support the body’s healing process and improve health outcomes. Rather than replacing traditional medicine, complementary care enhances it — offering a more holistic, personalized approach to wellness.
It's common for terms like “complementary,” “alternative,” and “integrative” medicine to be used interchangeably, but there are important differences:
For those in Rancho Santa Fe who prioritize wellness, longevity, and proactive healthcare, complementary medicine offers a powerful, personalized path to lasting vitality — all delivered with integrity and compassion.
Hormonal changes are a natural part of aging — but that doesn’t mean you have to live with fatigue, weight gain, irritability, or low libido. At our clinic, we offer Bioidentical Hormone Replacement Therapy (BHRT) as a safe, effective way to restore balance and vitality for both men and women.
BHRT is one of our most in-demand services for Rancho Santa Fe patients who want to age with clarity, confidence, and energy — without relying on synthetic hormone drugs.
Even the most health-conscious individuals can suffer from hidden nutrient deficiencies or suboptimal metabolism. At the Stengler Center, we use functional lab testing to identify nutritional gaps and create personalized nutrition plans that support energy, immunity, and hormone balance.
Every supplement recommendation is backed by clinical evidence and tailored to your lab results — using only medical-grade products with verified purity and potency. This approach allows our Rancho Santa Fe patients to experience real, lasting improvements without the guesswork of over-the-counter supplementation.
For those looking to boost immunity, restore energy, or recover more quickly from illness, IV nutrient therapy offers fast, targeted results. Unlike oral supplements, intravenous delivery ensures that vitamins and minerals go directly into the bloodstream, bypassing the digestive system for maximum absorption and efficiency.
Each IV protocol is administered safely under clinical supervision, based on your personal needs and lab results. For many of our Rancho Santa Fe patients, IV therapy becomes a regular part of their wellness routine.
Digestive issues are often the root of broader health problems — from inflammation and fatigue to autoimmune dysfunction and nutrient deficiencies. At the Stengler Center, we offer a thorough, functional approach to digestive health that gets to the source of your symptoms and supports long-term gut healing.
We use advanced testing to assess your gut health in detail:
Our integrative model ensures that every digestive treatment plan is tailored to your body and lifestyle, empowering Rancho Santa Fe patients to reclaim digestive health and overall wellness — naturally.
When energy crashes, sleep becomes restless, and motivation fades, the adrenal and thyroid glands are often at the center of the imbalance. Unfortunately, conventional medicine may overlook the early signs of adrenal fatigue or subclinical hypothyroidism — leaving patients frustrated and untreated. At the Stengler Center, we take a comprehensive, functional approach to restoring hormone balance and vitality.
Rather than relying solely on prescriptions, we use a whole-person strategy to balance these essential systems — supporting thyroid function, adrenal resilience, metabolism, and mental clarity.
When it comes to long-term health, Rancho Santa Fe residents deserve more than symptom-based care. You deserve a healthcare experience that’s personalized, proactive, and rooted in truth. At the Stengler Center, we blend modern diagnostic tools with evidence-based natural therapies to help you not only feel better — but stay well.
With Dr. Mark Stengler, you’re partnering with a provider who offers more than clinical expertise. You’ll experience compassionate, faith-affirming care that treats the whole person — body, mind, and spirit.
If you're ready to move beyond medications and quick fixes and take ownership of your health with confidence, we invite you to begin your journey with us today.
