About Dr. Lifestyle Clinic

Thoughtful integrative primary care for chronic and complex health concerns

 

Dr. Lifestyle is a physician-led integrative primary care clinic in Newport Beach, Orange County, dedicated to supporting individuals with chronic, autoimmune, and complex health concerns. Many of our patients arrive feeling unheard, dismissed, or overwhelmed by ongoing symptoms. Our role is to slow things down, listen carefully, and bring clarity to what’s been confusing

.We combine evidence-based primary care, integrative medicine, and lifestyle-focused strategies to create care plans that are practical, personalized, and designed for long-term stability—not short-term fixes. Dr. Micah Yu and Dr. Melissa Mondala lead the clinic with a shared belief that lifestyle medicine should form the foundation of healthcare. Their work integrates modern diagnostics, functional and integrative frameworks, and compassionate clinical judgment to better understand root causes and guide meaningful improvement.

While medications are used when appropriate, care is always informed by a broader understanding of nutrition, environment, physiology, stress, and daily life. Over time, this approach has helped patients move forward with greater confidence, clarity, and support. We remain committed to continuous learning, advanced medical education, and collaboration within the integrative medicine community—so patients feel informed, respected, and actively involved in their care.

Our Approach

Chronic symptoms are rarely one-dimensional. We take time to understand your medical history, lifestyle, environment, and stress physiology—then thoughtfully integrate clinical care with supportive strategies
that fit your life.

Medication may be part of the plan when appropriate, but it is rarely the only tool.
Our focus is root-cause clarity, long-term partnership, and sustainable care.

Integrative Medicine

A balanced approach that combines conventional primary care with integrative and lifestyle-based therapies. Every recommendation is guided by safety, evidence, and your individual needs.

Functional Medicine

A root-cause lens that examines how systems and patterns—
such as inflammation, hormones, gut health, immune response, and metabolic function—interact to influence symptoms over time.

Who We Support

and metabolic concerns, mood and stress-related health challenges, and environmentally triggered illness.
