My approach blends the science of the body with the art of individualized healing, creating a path toward holistic wellness that feels both effective and deeply nourishing.
With a focus on functional medicine, I provide evidence-based strategies rooted in clinical excellence, while honoring the body’s innate wisdom. Every session is guided by deep listening, compassion, and intention, helping clients restore energy, improve balance, and strengthen overall vitality.
I believe true healing goes beyond symptom management—it’s about empowerment, alignment, and sustainable transformation from the inside out. By integrating advanced nutrition science with intuitive care, I help clients experience wellness as a ritual of self-respect and self-love.
My vision is to redefine holistic health as an elevated, supportive journey where functional nutrition, naturopathic medicine, and integrative care come together to inspire lasting change.

What is Clinical Nutrition?
Certified Functional Medicine Practitioner & Nutritionist
Clinical Nutrition is the advanced science of how nutrients shape human health—at the cellular, metabolic, and functional level. It considers not just what you eat, but how your body uniquely absorbs, utilizes, and detoxifies nutrients. Through this lens, nutrition becomes a precision tool for prevention, healing, and deep vitality.
At Sifford Wellness & Nutrition, we practice Functional Clinical Nutrition—a root-cause, systems-based approach that integrates cutting-edge research, advanced functional testing, and compassionate listening. Every plan is fully personalized, designed to uncover the why behind your symptoms and guide you into a more vibrant, resilient state of well-being.
Clinical nutrition can be used to support or help reverse chronic conditions such as metabolic dysfunction, hormone imbalance, digestive disorders, fatigue, infertility, autoimmune conditions, and more.
What We Specialize In
Digestive Health
Your gut influences every aspect of your health. I work with clients who experience bloating,
constipation, diarrhea, reflux, food intolerances, or conditions such as IBS, IBD, or SIBO. Together, we
uncover what’s driving your symptoms and restore balance so your digestion supports, rather than
limits, your life.
Hormonal Balance
Hormones shape how you feel, function, and move through life. Whether you’re navigating PMS, PCOS,
endometriosis, perimenopause, menopause, or thyroid imbalances such as hypothyroidism and
Hashimoto’s, I help bring your hormones back into rhythm. Through personalized nutrition and lifestyle
strategies, we create steadiness in mood, metabolism, and energy.
Mental & Emotional Wellbeing
Nutrition plays a central role in brain health. Many of my clients experience anxiety, depression,
irritability, brain fog, or poor focus. Whether linked to nutrient depletion, gut-brain imbalance, chronic
stress, or hormonal shifts, we identify the root contributors and create a plan that supports emotional
balance, mental clarity, and resilience.
Cardiometabolic Health
Heart and metabolic health go far beyond numbers on a lab report. I support clients with prediabetes,
type 2 diabetes, metabolic syndrome, insulin resistance, elevated cholesterol, and hypertension. My
approach focuses on restoring balance through nutrition, functional testing, and sustainable lifestyle
shifts—helping to protect heart and vascular health long-term.
Healthy Aging, Longevity, Stress & Resilience
Aging is natural, but how we age is influenced by nutrition, movement, and resilience. Whether you’re
facing concerns with bone density, memory, cognition, cardiovascular health, or immune function, I
guide you with strategies that enhance vitality, slow decline, and promote graceful, healthy aging.
Women's Health & Fertility
From irregular cycles and PMS to PCOS, fertility struggles, postpartum recovery, and menopause,
women’s health concerns are often deeply connected to nutrition and hormones. I support women in all
life stages with personalized care to optimize reproductive health, restore balance, and nourish the body
for the future.
Unexplained/Chronic Symptoms& Multi-System Conditions
Sometimes symptoms don’t fit neatly into a diagnosis. Fatigue, joint pain, headaches, skin breakouts, dizziness, or digestive discomfort may be brushed aside as “normal” or “stress.” I specialize in connecting these patterns and identifying hidden root causes so you can finally get clear answers and a path toward healing.
Immune & Autoimmune Health
Chronic inflammation and immune imbalance often lie beneath conditions like Hashimoto’s thyroiditis,
rheumatoid arthritis, psoriasis, eczema, or frequent infections. I help you strengthen your defenses,
calm inflammation, and create balance in immune function, supporting both prevention and symptom
relief.
Weight & Body Composition; Metabolic Flexibility
Weight concerns are often the body’s way of signaling imbalance. Instead of quick fixes, I focus on root
causes such as blood sugar dysregulation, thyroid issues, inflammation, stress, or low muscle mass.Clients may experience shifts in weight, inches, or body composition, but the real goal is sustainable
health and freedom from the dieting cycle.
Stress & Resilience
Chronic stress can leave you feeling wired, tired, or both—impacting sleep, hormones, digestion, and
immunity. Whether you’ve been told you have “adrenal fatigue,” struggle with insomnia, or feel unable
to recover from stressors, I help support the nervous system and rebuild resilience so you feel grounded
and replenished.
Working With Yana
I’ve had the privilege of working with Dr. Yana Sifford as both a student and colleague. She was an exemplary 4.0 doctoral student and quickly became the head associate in my practice, a rare honor. Dr. Sifford brings exceptional clinical skills, diagnostic insight, and calm professionalism under pressure. She leads complex cases, mentors interns, and consistently earns the trust of patients. In more than 20 years of practice, I continue to learn from her expertise.
Dr. Sifford will change many lives, and help many patients, but her best asset is her humbleness, empathy and true dedication to her craft. I have not only been blessed having her in my practice, but it has been a great honor working side by side.
Patients facing chronic disease will be in outstanding hands, she is dedicated, empathetic, and truly exceptional.
