Root Cause Medicine
WE BELIEVE IN...
A personalized approach to medicine rooted in partnership.
We view health through the lens of a garden. To thrive, we first uproot the factors that contribute to dysfunction, such as processed foods, environmental toxins, sedentary habits, and unhelpful thought patterns, and then intentionally replant the foundations of health, including real food, hydration, restorative sleep, movement, and a renewed mindset. This functional medicine approach focuses on the individual drivers of both health and disease and offers a personalized way to care for patients with chronic illness. Through targeted advanced testing, nutritional recommendations, and precision supplementation guided by lab data, we are able to support each patient based on their unique needs and create care plans that promote lasting health and well-being.

Foundational
Assessment
The Foundational Assessment is just that, the foundation of your care journey - and is designed to move beyond symptom management to help you understand the root cause, the "why" behind your symptoms, and what can be done to correct them at the root cause. The Foundational Assessment is a one-time, 3-visit cluster of appointments that serves as the foundation and springboard for your care journey. This assessment can be used as a standalone evaluation for optimal wellness or as the required entry point before joining the ongoing Next Chapter Partnership Membership.
What Is Offered:
Clinical Components: Throughout the assessment, you will receive a comprehensive evaluation that includes:
- A comprehensive history, symptom review, and goal assessment.
- A physical examination.
- An InBody 580 Body Composition Analysis.
- A detailed review of Advanced Biomarkers, which look at metabolic markers, nutrient status, an expanded thyroid assessment, inflammatory markers, lipids, and hormones.
The Process (The 3-Visit Cluster)
1. Initial Visit (75 to 90 minutes, in-person). This is a deep-dive clinical assessment with Dr. Marshall. During this comprehensive visit, you will:
- Perform the InBody Vital Signs and Body Composition Assessment.
- Review your health timeline, current symptoms, health history, areas of focus and goals.
- Undergo a physical exam.
- Review your advanced biomarker lab results.
- Discuss the possible underlying patterns contributing to your health concerns and begin outlining the next steps to build your personalized care roadmap.

-Review Dr. Marshall's overall impression of what is driving your symptoms at a root level.

- Discuss recommendations for further advanced testing if choosing ongoing care

-Learn how to access your resources, get your questions answered, and explore ongoing membership options.
3. Implementation Visit (2-3 weeks after the Care Plan Review): This is a short follow-up visit focused on navigating your new plan. This is conducted by our Nurse Health Coach and is designed to:
- Review how the implementation of your care plan is going.
- Discuss your wins and overcome any challenges or obstacles.
- Answer any remaining questions you may have.
- Revisit membership options to ensure you feel clear, confident, and supported if you choose to transition seamlessly into ongoing care.

Next Chapter
Membership Plans
What is Chapter 1: The Integrative Partnership? Available exclusively within 60 days of your Foundational Assessment, this 12-month membership is for patients ready to dive deeper, address chronic dysfunction, and uncover the root causes of their symptoms.
We limit enrollment to this 60-day window for a vital reason: your clinical data is still fresh, and your personal momentum to embrace lasting change is at its peak. Capitalizing on this initial energy allows us to build your roadmap while your history and goals are top-of-mind, ensuring we step right into your next chapter without losing valuable ground. This is where lasting restoration begins.
Building directly on what you learned in your assessment, we will design personalized clinical protocols using advanced diagnostic testing, actively adjusting your care based on how your body responds. This comprehensive approach builds a clinical relationship that extends far beyond a single appointment, giving you the steady support and communication required for deep healing. Our process seamlessly integrates Dr. Marshall's medical skill set, our Nurse Health Coach's behavioral strategies, and your own daily habits to systematically work to resolve multi-system health issues from the ground up.
The Process: What is Offered in Chapter 1: The Integrative Partnership?
Real healing takes time, structure, and consistent support.

5 Implementation Visits: Thirty-minute telehealth sessions with our Nurse Health Coach focused on behavior, lifestyle interventions, and seamlessly building your daily wellness habits.
A Note on Complex Care
True wellness isn't one-size-fits-all. As a general rule, health conditions that took years to develop or actively affect multiple body systems require more intensive, long-term intervention.
For most patients, this foundational ten-visit rhythm is highly sufficient for their healing journey. However, if your unique health challenges require clinical care beyond this core cadence, your membership plan can be seamlessly expanded with additional custom visits.
Advanced Diagnostic Testing: The ordering, interpretation, and treatment implementation of advanced diagnostics not typically used in conventional medicine. This deep dive into your health can include advanced stool microbiome analysis, adrenal profiles, breath tests, and organic acid analysis.
Continuous Support: Ongoing portal messaging directly with the doctor and the nurse health coach, ensuring continuous communication between visits.
Supplement Discount: A 15% discount on all supplements ordered through Next Chapter’s online dispensary (Fullscript).
Coming Soon: Monthly classes. Newsletter.
Please note: While Dr. Marshall does not serve as your primary care physician, our team is fully committed to a collaborative approach. With your permission, we gladly partner with your PCP by sharing progress notes and advanced lab results to support your unified care.

InBody Body Composition Analysis
Rather than relying on a misleading bathroom scale, true health requires looking beyond weight alone. To better understand your body's interconnected systems, we need more than a single number on the scale. The InBody 580 is a medical-grade, non-invasive body composition assessment that, in just 30 seconds, provides a detailed picture of what your body is made of, including muscle, body fat, and hydration. This allows you to track meaningful changes in your health, not just how much you weigh.
**This InBody Analysis is included with the Foundational Assessment. However, it is offered as a stand-alone service for those only interested in body composition analysis.
What is Offered?
An InBody analysis is a non-invasive screening tool that uses bioelectrical impedance analysis (BIA) to estimate body composition measurements, including but not limited to body fat percentage, skeletal muscle mass, total body water, and related metrics..These measurements may be useful for:
- Tracking changes in your metabolism and body composition over time
- Monitoring muscle mass to help maintain strength and healthy aging
- Watching changes in inflammation, hydration, and fluid balance
- Helping measure progress and stay accountable
The Process
To get started with the InBody Assessment, you will follow a simple, streamlined process:
1. Purchase the service online.
2. Complete an intake form through the practice's Electronic Health Record system.
3. Schedule your appointment to come in for your measurement.
Price Options
The assessment is offered in three different pricing tiers depending on your needs:
$75 (The Deep Dive): This covers your initial body composition analysis along with a 30-minute physician consultation.
$45 (The Progress Check): This includes a follow-up analysis and a 30-minute physician consultation to continuously monitor your progress.
$25 (Measurement Only): A quick "stop-in" appointment after your initial visit strictly to take your measurements and track your data, without a physician consultation.
