A double specialist, at your address this week

The specialist comes to you.

Private consultations at your residence with a specialist double board-certified in Internal Medicine and Endocrinology. No waiting rooms, no queues, no rushed ten minutes. A full, unhurried consultation in the comfort of your own home, by secure video anywhere in Spain, or at a private partner clinic on Avenida Ricardo Soriano, Marbella.

Consultations are conducted in English or Dutch.

WhatsApp the Practice Send an Enquiry I reply personally, usually the same day.

A planned service, not urgent care. This is elite, by-appointment specialist medicine, not an emergency or urgent-care service, and not general medicine on demand. In a medical emergency, call 112 or go to the nearest hospital.

Specialist care, brought to your door

Instead of travelling to a clinic and waiting to be seen, I arrange everything around you.

Specialist Consultation at Home

A thorough, unhurried consultation at your residence with a double board-certified specialist in Internal Medicine and Endocrinology. Your history, your questions and your health plan, taken seriously and given the time they deserve.

New

Ultrasound at Home

Performed at your residence, by me. Thyroid ultrasound, and nutritional ultrasound: a precise look at visceral fat and the quadriceps muscle, two of the most telling markers of metabolic and nutritional status, with the findings explained to you in plain language on the spot.

Secure Video Consultations

The same specialist attention wherever you are in Spain, by encrypted video. Ideal for follow-ups, second opinions and consultations when you are travelling.

Diagnostics at Your Residence

Comprehensive blood analysis arranged at your home. I review the results personally and explain them in a language you actually understand.

Surgical Coordination & Second Opinions

When surgery is on the table, one doctor on your side: an independent second opinion, help choosing the right surgeon, and personal guidance from first question to recovery.

Concierge Physiotherapy

For established clients, home visits by a physiotherapist I selected personally. Availability is extremely limited and offered by arrangement only, which is precisely why it is coveted.

At Your Residence

Ultrasound at home

The equipment travels with me. Each examination stands on its own. Choose the one that answers your question, or more than one, and I read and explain it in the room, the moment it is done. No radiation, no clinic, no waiting for a report.

Three separate examinations. You choose which one you need.

Thyroid

Thyroid Ultrasound

3 to 7% by hand.
19 to 68% on ultrasound.

Reported nodule prevalence, palpation against imaging. Blood values describe how the gland works. The image describes what is in it. Most are benign, and you are told so plainly. It matters most if you have an abnormal thyroid function test, a swelling you can see or feel, a known nodule under follow-up, previous radiation to the neck, or a family history. Reported in the structured international format, by an endocrinologist.

Visceral Fat

Visceral Fat Ultrasound

Risk that is independent of BMI.

Weight, BMI and the mirror describe the fat you can see. Ultrasound measures the deep fat directly, in millimeters, in minutes. CT and MRI remain the reference standard, and both mean a hospital and a wait.

Muscle

Muscle Quality, Quantity and Functionality Ultrasound

Strength, measured. Not estimated.

In the Health ABC cohort it was strength, not mass, that tracked with mortality, and a 2023 meta-analysis put low skeletal muscle mass index against all-cause mortality at a pooled relative risk of 1.57. So both are measured here: grip strength by hand dynamometer, the way the cohort studies did it, and the muscle itself on ultrasound at the quadriceps, thickness and structure, at your own table. Both repeat over time, which is how you see whether anything you do is working.

Wang Y et al, PLoS One 2023. Newman AB et al, J Gerontol A Biol Sci Med Sci 2006. Ask about muscle ultrasound

Ultrasound is an examination, not a substitute for clinical assessment. Findings are interpreted individually, and further investigation is advised only where it is clinically indicated.

Beyond The Image

What the scan cannot tell you

Ultrasound measures how much muscle is there. It cannot tell you whether that muscle works, and it cannot watch you over time. Two further assessments do. Each is requested on its own, and I perform each of them at your residence.

Structure is one half of the answer. Function is the other.

Grip Strength

Grip Strength Measurement

1,855,817 people.
34 studies. One measurement.

An umbrella review from Newcastle, Manchester, Cambridge, North Carolina, Alberta and Freiburg pooled 34 studies covering 1,855,817 people. Higher grip strength at baseline carried a relative risk of death of 0.72 (95% CI 0.67 to 0.78). Across 15 studies it was 0.84 for cardiovascular death, and across 7 studies 0.76 for becoming disabled. The authors grade all three as highly suggestive rather than proven, and say so plainly. Calibrated dynamometry, performed to protocol, recorded against your own previous readings and reported alongside the muscle ultrasound. Repeated at each assessment, the trajectory becomes the finding.

Handheld patient monitor on a table displaying oxygen saturation, pulse rate, perfusion index and waveform
Oxygen And Circulation

Oxygen and Circulation Monitoring

Saturation, pulse, perfusion.
Continuous, with the waveform.

A bedside patient monitor, not a fingertip clip from a pharmacy. Oxygen saturation, pulse rate, perfusion index and the plethysmographic waveform they are read from, followed continuously rather than glanced at once. This is the assessment for a chest infection you would rather not take to a hospital, for the days after a procedure, and for anyone whose oxygenation and circulation should be watched by a specialist in their own room. Requested on its own, or added to a consultation at your residence.

Performed and interpreted by me at your residence. Available as a single assessment or across consecutive days. Ask about monitoring at your residence

Grip strength is a functional measurement, not a diagnosis. Published reference values are derived from research dynamometers and do not transfer directly between devices, so the reading is used to follow change over time on the same calibrated instrument rather than to place you on a published percentile.

The Specialist

The long way round

Concierge medicine is bought on trust, so it is worth knowing how I got here.

Dr de Windt, MD
Dr de Windt, MDDouble board certified in Spain • Endocrinology and Internal Medicine • Número de colegiado 292911860A fully functioning specialist with a vast professional network across Spain.
Board Certified

Endocrinology

Board certified in Endocrinology and Nutrition, the specialty that exists for hormones, metabolism, the thyroid and the glands. Full specialist training in the Spanish hospital system, in the field this work actually sits in.

Board Certified

Internal Medicine

Board certified in Internal Medicine, the specialty of complex adult disease and the one other doctors call when a case does not fit. It is why your heart, your kidneys and your medication stay in the same conversation, and why what turns out not to be hormonal still gets recognized.

Expert Courses

Infectious Disease

Expert courses in infectious diseases in emergency medicine and in tropical infectious disease. An international practice sees people who travel, and fever after a trip is not a hormone problem.

ASESA

Andrology Certified

Trained in andrology, fertility and sexual medicine with ASESA, the Spanish association for the field, across the 2025 and 2026 editions of its national course. Most doctors never train in this at all.

Expert Course

Ultrasound Certified

Expert-course trained in bedside ultrasound and years of daily use through hospital medicine. Every ultrasound offered on this page is performed and read by me, in the room, not sent away to a report queue.

Alumno de Honor

Best Of His Class In Medical School

Best academic record of my medical school class, then six years as a general practitioner in a Dutch-organized system before any specialty. General medicine first is why nothing about you gets treated in isolation.

Two Health Systems, Four Languages

Dutch Training, Spanish Practice

Northern European patients arrive with expectations shaped by a different system: direct answers, evidence before hierarchy, no theatre. I know both systems from the inside. Cultures also differ in how illness is discussed and how directly news should be delivered; I pay attention to how you prefer to be spoken to. Consultations are conducted in English or Dutch.
