SourceMD Integrated Wellness Solutions: Dr. David Larson in Encinitas, CA

Last updated July 29, 2026

At 345 Saxony Rd Suite 206 in Encinitas, California, Dr. David Larson runs a medical practice that doesn't fit neatly into the conventional healthcare mold. SourceMD: Integrated Wellness Solutions draws patients from across the region who are looking for a physician willing to spend real time understanding the full picture of their health, not just the presenting complaint. Dr. Larson, known to most of his patients simply as Dr. Dave, practices integrative medicine with a functional medicine foundation, addressing the root causes of both mental and physical health conditions rather than managing symptoms in isolation.

The practice holds a 5.0 rating across 111 reviews, a reflection of the patient-centered philosophy that shapes every appointment. What sets SourceMD apart is the breadth of Dr. Larson's credentials: he's double board-certified by the American Academy of Family Physicians and the American Board of Psychiatry and Neurology, a combination that allows him to treat the full spectrum of mental and physical health concerns under one roof.

Encinitas has long attracted health-conscious residents, and SourceMD fits naturally into that culture. But Dr. Larson's approach goes well beyond lifestyle coaching or general wellness advice. His practice is grounded in systems biology, a scientific framework that looks at how interconnected physiological systems influence one another, and he applies that framework to develop personalized care plans for each patient.

How SourceMD Was Founded and What Drives Dr. Dave

Dr. David Larson built SourceMD around a conviction that conventional medicine, for all its strengths, often misses the deeper patterns underlying chronic illness and diminished well-being. His interest in functional medicine led him to study how lifestyle interventions, nutrition, and a whole-person perspective can produce health outcomes that purely symptom-focused treatment rarely achieves. The name SourceMD reflects that philosophy directly: the practice is oriented toward finding the source of a patient's health challenges, not just treating what's visible on the surface.

Patients who come to SourceMD frequently arrive after years of working through the standard medical system without getting to the bottom of what's affecting them. Dr. Larson's dual board certifications in family medicine and psychiatry and neurology give him an unusually wide clinical lens, allowing him to consider how mental health, neurological function, and physical health interact in a single patient's experience.

SourceMD Services and Specialties in Encinitas, CA

SourceMD offers a range of services that span both mental and physical health, with Dr. Larson's functional medicine training running through all of them. The practice's systems biology approach means that a patient presenting with fatigue, for example, might have their cardiovascular function, hormonal balance, gut health, sleep patterns, and mental health status evaluated together rather than separately.

Core areas of care at SourceMD include:

• Functional medicine evaluation and root-cause analysis
• Integrative treatment of mental health conditions, including anxiety, depression, and mood disorders
• Neurological health and cognitive wellness
• Lifestyle medicine, including evidence-based nutritional and behavioral interventions
• Preventive care and long-term health optimization
• Management of chronic physical health conditions through a whole-body lens

One distinguishing feature of the practice is Dr. Larson's commitment to staying current with the medical literature. He incorporates evidence-based methods rather than relying solely on conventional protocols, which means patients benefit from approaches that reflect recent research rather than standard-of-care defaults. That rigor, combined with a genuinely personalized approach, is what patients consistently point to when describing why they stay with the practice long-term.

Team and Leadership at SourceMD

The team at SourceMD is small and deliberately so. Dr. Larson maintains a practice environment where patients are known as individuals, not case numbers.

• Dr. David Larson, MD: Integrative medicine physician, double board-certified by the American Academy of Family Physicians and the American Board of Psychiatry and Neurology. Known to patients as Dr. Dave, he leads all clinical care at SourceMD and focuses on functional medicine and whole-person health.
• Cindy Clippinger, Office Manager: Cindy brings more than 20 years of administrative experience to the practice and is credited with creating a family-like atmosphere at SourceMD. Her role spans office management and direct administrative support to Dr. Larson.
• Halleh Radvar, Medical Assistant: A Boston University graduate with a Health Science background, Halleh is working toward medical school while contributing to patient care at SourceMD. Her academic grounding in health science complements the practice's evidence-focused culture.

In the Press

Dr. Larson's expertise extends beyond his clinical practice. He has contributed to peer-reviewed publications, including articles in The American Journal of Cardiology and Pediatric Dermatology. Published contributions to journals of that caliber reflect a physician who engages seriously with the research community, not just the clinical one. For patients, that engagement translates into a provider who brings academic rigor to everyday care decisions.

What Patients Say About SourceMD

The 111 reviews that have shaped SourceMD's 5.0 rating tell a consistent story: patients feel genuinely understood, and they see measurable results. The themes that emerge from patient accounts center on Dr. Larson's depth of knowledge, his ability to explain complex health concepts clearly, and the sense that the practice is invested in long-term outcomes rather than quick fixes.

Dr. Larson is extremely knowledgeable, up to date on the literature, and implements cutting edge evidence-based methods in his practice.

- Nikolas London

That emphasis on evidence-based care shows up across patient accounts. Keith Harding's experience captures the long-arc nature of the work at SourceMD particularly well:

I started seeing Dr. Larson two years ago, and he has helped me get to the healthiest I have been in 20 years, and we're still making progress.

- Keith Harding

For patients dealing with complex or layered health challenges, the sense of safety and depth matters as much as clinical outcomes. Michelle Cronje Hopper described that dimension of her experience directly:

Dr. Larson's high level commitment and in-depth knowledge of integrated wellness has felt safe and exciting to work with.

- Michelle Cronje Hopper

Beyond individual outcomes, patients also note the broader atmosphere at the practice. One reviewer described SourceMD as 'a breath of fresh air in the medical environment these days,' pointing to the staff's willingness to understand a patient's goals before charting a course of treatment. That culture of attentiveness runs from the front desk through every clinical interaction.

Location and Community: SourceMD in Encinitas, CA

SourceMD: Integrated Wellness Solutions is located at 345 Saxony Rd Suite 206, Encinitas, CA 92024. Encinitas has a well-established identity as a health-oriented community, and that context shapes the kind of patients who find their way to Dr. Larson's practice. Many arrive already motivated to make meaningful changes; they're looking for a physician who can match that motivation with clinical depth.

The broader San Diego North County area, of which Encinitas is a central part, has seen sustained real estate appreciation averaging around 8.5% annually in recent years, with projections settling closer to 4.2% going forward. That trajectory reflects a community where long-term residents are invested in quality of life across all its dimensions, including healthcare. For a practice like SourceMD, which builds multi-year relationships with patients, that kind of stable, engaged community is a natural fit.

Why Choose SourceMD: Integrated Wellness Solutions

Dr. Larson's double board certification in family medicine and psychiatry and neurology is genuinely uncommon, and it gives SourceMD a clinical range that most integrative practices can't match. Patients dealing with conditions that sit at the intersection of mental and physical health, which is more of them than conventional medicine typically acknowledges, benefit from having both dimensions addressed by the same physician using the same whole-person framework.

But credentials alone don't explain the practice's reputation. The 5.0 rating across 111 reviews reflects something harder to quantify: a practice where patients feel known, where appointments involve real listening, and where the goal is lasting health rather than managed decline. For anyone in the Encinitas area seeking a physician who treats the whole person, SourceMD is a practice worth a serious look.
