When access
is not enough.

A retained physician-scientist relationship for care that requires unusual depth, continuity, and judgment.

The relationship

Room for ten. Attention to one.

Ten patients, by design. The breadth of medicine, focused on one.

01 / Assemble

Start with the whole picture.

Bring your history, priorities, and experience into view.

02 / Interpret

Find what matters.

See the pattern, and decide together what better would mean to you.

03 / Hypothesize

Make a considered choice.

Decide what to try, what to watch, and when to review.

04 / Measure

Attend to the response.

What happens may not match what was expected. That difference matters.

05 / Revise

Keep the aim. Revise the expectation.

The record stands. The plan adapts.

Who

For people whose care cannot be understood in fragments.

Many moving parts

Care involves several specialists, a long medical history, or decisions that depend on seeing the whole picture rather than one problem at a time.

A consequential decision

A diagnosis, treatment choice, or change in health calls for careful review, additional perspective, and a physician who can stay with the question.

Prevention that requires judgment

The goal is not simply more testing, but a strategy connecting risk, evidence, personal priorities, and response over time.

Sustained stewardship

One physician holds the context, coordinates the work, and helps the plan evolve.

The retained relationship

Physician time for the work between appointments.

A relationship shaped around you. Dedicated physician time, coordination, and continuity, with scope matched to complexity and need.

Dr. Sanger usually serves as your primary physician and holds the whole medical picture. Where it serves you better, he works alongside your existing primary care physician.

Dedicated physician capacity

An annual reserve of physician time, within and beyond the consultation.

Deep record review, research, advocacy, referrals, and correspondence

Room for consequential decisions that cannot be compressed into a routine visit

Direct communication and after-hours support

Secure, direct channels and response expectations matched to the clinical situation.

Direct, secure communication with Dr. Sanger

After-hours phone access, with trusted physician backup

Specialist coordination and advocacy

One physician retains the whole picture while outside expertise is brought in deliberately.

Dr. Sanger can join key specialist conversations when useful

Thoughtful scheduling and preparation around important consultations

Recommendations reconciled across specialists and institutions

An extended clinical team

The retained relationship includes practical support for nutrition, movement, medication, and recovery.

A vetted team is brought in around your priorities rather than as disconnected services (included in the fee)

Dr. Sanger retains the medical through-line

Longitudinal diagnostics

Testing selected to answer a question. Findings followed over time.

Thoughtfully selected laboratory, imaging, and physiologic testing included

Measurements interpreted in the context of history, goals, and changing response

New information is incorporated into an evolving plan

What the relationship includes

Biomedical informatics, in practice

A rare background, used with restraint.

Biomedical informatics is part of Dr. Sanger’s medical craft, not a product layered on top of it. Computational methods extend the field of view across records, evidence, and change over time. Interpretation and care remain physician-led.

Make the record legible

Reconcile records, imaging, laboratory results, and specialist notes into a legible whole, with each finding connected to its source.

Search beyond the obvious

Retrieve and compare guidelines, trials, specialist perspectives, and emerging literature against your actual eligibility, risks, and goals.

Surface gaps and contradictions

Flag conflicts, missing measurements, assumptions, and unresolved questions for deliberate physician review.

Follow trajectories

Relate interventions to subsequent symptoms, function, biomarkers, and clinical events so the plan can learn from response over time.
