More testing doesn’t always mean better care.
The right test does.

Advanced preventive screening can help uncover health risks that routine care may overlook. Dr. Marshall carefully recommends tests that provide meaningful insight and support a smarter, more personalized prevention plan.

Best For

Ideal for adults who want a clearer, more personalized cancer screening plan — especially those managing care across multiple providers or feeling unsure about what screenings they truly need.

Common Concerns

Patients receive personalized guidance, coordinated testing, clear follow-up on results, and compassionate support if additional evaluation is needed.

What Makes This Different

Effective prevention requires more than ordering tests. It requires thoughtful follow-up, coordinated care, and a clear plan so important details don’t fall through the cracks.

——————– The Approach

Good prevention isn’t about collecting more information — it’s about knowing what information truly matters.

The market for “executive health” and advanced preventive screening has grown considerably — and with it, a culture of more tests meaning better prevention. It doesn’t, automatically. A test that returns an ambiguous result, requires a cascade of follow-up studies, and ultimately changes nothing about how you live or what medications you take didn’t help you. It may have harmed you.


The right framework is simple: does this test result — whether normal or abnormal — meaningfully change what we would do? If yes, it’s worth ordering. If the answer is “probably not,” the honest recommendation is to skip it.


That kind of selectivity requires a physician who knows you — your history, your risk factors, your goals, your anxiety tolerance, and what’s already been done. It’s not something a panel of 40 tests can replicate.

“My goal is to recommend focused testing that truly improves decision-making — not unnecessary testing that creates stress without improving outcomes.”

——————– The Framework

How Dr. Marshall decides
what's worth ordering

Dr. Marshall focuses on tests that provide information you can actually use — tests that help guide better prevention and treatment decisions.

Worth Pursuing When…
The result would change what we do
Screening is what happens when there are no symptoms — it’s how we find disease early, before the body is raising any obvious flags. The entire premise depends on doing it on schedule, before something develops that would have given us a different reason to test.

Colonoscopy, mammography, Pap smears, low-dose CT lung screening, and PSA testing are all screening tools — used proactively in populations with elevated risk based on age, sex, family history, or exposure.

The goal of screening is to shift the stage of diagnosis — to catch cancer at stage one instead of stage three. That shift is where survival rates change dramatically.
Less Useful When…
The result is unlikely to change the plan
Diagnostic testing is different from screening — it’s triggered by a symptom, an abnormal screening result, or a new clinical concern. A colonoscopy performed because of rectal bleeding is diagnostic, not screening. A biopsy after an abnormal mammogram is diagnostic.

The distinction matters practically because insurance coverage, referral pathways, and urgency differ between the two. Patients often don’t realize their test was classified one way or the other until a billing issue arises.

Dr. Marshall helps patients understand exactly which category their testing falls into — and what the next step looks like regardless of which path they’re on.
——————– Testing Categories

Areas where advanced screening
can add genuine value

These are not a menu — they’re categories worth discussing based on your specific risk factors, history, and goals. The right conversation determines what belongs in your plan.
Cardiovascular & Vascular Screening
For patients where routine risk calculators leave meaningful uncertainty — particularly those with family history of early heart disease, borderline lipid values, or multiple modest risk factors that together may justify more aggressive prevention.
May include: coronary calcium scoring, carotid IMT, ABI, hsCRP, Lp(a)
Bone Health & Fracture Risk
Bone density evaluation is most relevant for postmenopausal women, patients on chronic steroid therapy, those with prior fractures, or patients with low body weight or significant risk factors for osteoporosis. A DEXA scan clarifies whether preventive treatment is appropriate.
May include: DEXA scan, FRAX score, vitamin D and calcium assessment
Sleep & Metabolic Evaluation

For patients where sleep apnea, metabolic dysfunction, or hormonal contributors are suspected but not yet evaluated. Untreated sleep apnea is one of the most common drivers of resistant hypertension and poor weight control — and it’s frequently missed without a targeted sleep study.

May include: sleep study referral, comprehensive metabolic panel, thyroid evaluation, hormone assessment
Advanced Metabolic & Inflammation Labs
Beyond standard lipid panels and basic metabolic labs — for patients with elevated risk, prior abnormal results, insulin resistance, or unexplained fatigue and inflammation where a deeper metabolic picture would guide treatment decisions.
May include: ApoB, Lp(a), insulin levels, hsCRP, homocysteine, advanced thyroid panel
——————– How It Works

From conversation
to a plan that means something

Advanced screening is only as useful as the thinking that goes into choosing it — and the follow-through that comes after. Here’s how that process works at Mission Concierge Care.

01

Start With the Full Picture
Risk factors, symptoms, family history, labs already done, medications, goals. Before recommending any advanced testing, Dr. Marshall reviews what’s known and where the genuine gaps in the picture are. Tests fill gaps — they don’t replace the conversation.
02
Choose Tests That Change Decisions
The selection is specific and justified. Not a panel of possibilities — a focused set of tests where the results, whether normal or abnormal, would meaningfully alter the prevention plan. Every test earns its place in that conversation before it’s ordered.

03

Interpret Results in Context
Results come back in plain language — what they mean, what they don’t mean, and what changes. An abnormal finding doesn’t end with “we’ll keep an eye on it.” It leads to a specific next step, coordinated by Dr. Marshall, with the patient understanding exactly what’s happening and why.
——————– What’s Included

What a preventive screening
review actually covers

This is not a test-ordering service. It’s a physician-guided process that starts with your full clinical picture and ends with a focused plan — where every test selected has a reason, and every result leads somewhere specific.

The concierge model makes this possible because it creates the time for the kind of thinking that selective, high-value screening requires. There’s no advantage in choosing the right test if the interpretation and follow-through disappear afterward.
——————– Body Composition Tracking

One more tool worth
knowing about

The SECA body composition scan occupies its own category — not imaging in the traditional sense, but a precise tool for tracking fat mass, lean mass, and hydration status over time. For patients managing weight, metabolic health, or performance goals, it adds a layer of insight that standard weight tracking can’t provide.


It’s particularly valuable for patients using GLP-1 medications, those managing prediabetes or insulin resistance, and anyone whose weight loss plan needs to distinguish fat loss from muscle loss to actually work long-term.

——————– Good Questions

What people ask when they want
to go deeper on prevention

The questions that come from patients who’ve been around the healthcare system enough to be skeptical — and who deserve straight answers.
Why would I need advanced screening if I feel completely fine?
Some of the most important risk factors — coronary plaque burden, early metabolic dysfunction, silent hypertension, and developing bone loss — are asymptomatic for years. The question isn’t whether you feel fine today. It’s whether additional testing would meaningfully improve prevention decisions based on your history and risk profile. Sometimes the answer is yes. Sometimes the right recommendation is to wait.
Does more testing actually mean better care?
No — and this is worth saying directly. Better care comes from selecting the right test for the right reason. Unfocused screening creates false alarms, downstream testing cascades, unnecessary cost, and anxiety that can persist even after follow-up reassurance. A physician who recommends fewer, better-targeted tests is often providing higher-quality preventive care than one who orders everything available.
How does Dr. Marshall decide what’s actually worth ordering?
The deciding question is: would the result — normal or abnormal — meaningfully change what we recommend or what you would choose to do? If yes, it’s worth considering. If the honest answer is that the result won’t change the plan, the recommendation is to skip it. That assessment requires knowing your age, symptoms, history, family history, current labs, and goals — which is why it can’t happen without the full picture.
Will insurance cover advanced preventive testing?
It depends on the test and the clinical reason it’s ordered. Standard cancer screenings, sleep studies, and DEXA scans often have coverage pathways. Advanced cardiovascular imaging, some specialized labs, and elective screening tests may involve out-of-pocket cost. Dr. Marshall is transparent about this before tests are ordered — patients shouldn’t be surprised by a bill afterward.
How does this connect to heart disease prevention specifically?
Advanced cardiovascular screening can help clarify risk in patients where routine calculators leave meaningful uncertainty. A coronary calcium score, for example, can move a borderline patient clearly into “treat aggressively” or “lifestyle only” territory — changing a major treatment decision that a standard lipid panel couldn’t resolve. That’s exactly the kind of situation where additional testing earns its place.
What’s the difference between this and the cancer screening page?
The cancer screening page focuses on age- and risk-based recommended screenings — colonoscopy, mammography, cervical screening, lung CT, PSA. This page covers advanced testing that goes beyond standard recommendations: cardiovascular imaging, bone health, metabolic depth, sleep evaluation, and other targeted studies for patients who need a more thorough prevention picture. The two complement each other and are often part of the same plan.
