Private, specialist-led hormone optimization and medically supervised weight management, built to protect your muscle and your long-term health. By secure video, at your home, or at a private partner clinic in Marbella.
A hormone specialist, not a generalist with an interest in hormones.
Endocrinology is the medical specialty of hormones, and hormone treatment is also cardiovascular medicine: blood pressure, blood counts, lipids and long-term risk, the daily work of internal medicine. On the Costa del Sol most hormone care comes from general practitioners, from specialists in other fields, or from hospital departments with waiting lists. Here it is one physician, double board certified in Internal Medicine and Endocrinology, personally and without the waiting list.
That practice has ranged from CEOs in their fifties, sixties and seventies on carefully monitored TRT to elite athletes needing natural optimization of their own physiology. What you are buying is easy, prolonged access to a highly trained, seasoned specialist. The difference, explained.
Every program is designed by a single endocrinology specialist, integrated into a 12-month protocol, and delivered at home or on a private video call. Clinic visits are also available, at a private partner clinic on Avenida Ricardo Soriano, Marbella, for patients who prefer a clinical setting. Hormone and weight loss medicines are run as monitored programs, not renewal prescriptions.
Muscle mass, visceral fat and thyroid, measured in one session with medical-grade InBody 380 bioimpedance and point-of-care ultrasound, performed and read by the specialist himself. You leave with a written report and numbers you can act on.
A scale gives you one number and no explanation. This assessment tells you what you are actually made of: how much muscle you carry, where the fat sits, and what your thyroid is doing, before any treatment decision is made. It is the baseline every serious protocol is built on, and the reassessment months later is where progress stops being an impression and becomes a number. A DXA scan can always be ordered in addition to complete the picture.
Hormone care for women and men, taken equally seriously. For peri- and post-menopausal women: estradiol, progesterone and, where indicated, testosterone, chosen by route and dose to fit your risk profile, never a standard packet. For men: testosterone replacement with rigorous monitoring of estradiol, hematocrit, PSA, and cardiovascular markers.
The point is simple: to help you feel like yourself again, more energy, a clearer head, steadier mood, and strength you can rebuild. We do it properly and safely, watching your bloodwork closely the whole way, because good hormone care is as much about what we monitor as what we prescribe. For women, it is about moving through menopause on your own terms instead of being ruled by it. Nothing here is a one-size dose; it is your levels, your symptoms and your life, adjusted over time. It also covers continuing or starting hormonal treatment while you are visiting the coast, HRT, thyroid, contraception used for medical reasons, and testosterone where indicated.
Semaglutide, tirzepatide and dual-agonist protocols personalized to each patient's metabolic data, body composition, and hormonal profile. Body composition tracking and nutrition coaching layered with a sessional nutritionist partner. One of the fastest-growing areas in European private medicine, delivered by a specialist with the clinical depth to do it properly.
These medicines genuinely work, but the result depends entirely on how they are used. We start from your real metabolic and hormonal data, dose carefully, and protect your muscle while the fat comes off, so you end up lean and strong rather than just lighter and tired. Just as important is what happens when you stop, and we plan for that from day one so the weight stays gone. This is medical weight loss run by a specialist who tailors the dose, protects your muscle, and plans from day one for the day you stop.
Personalized fertility and hormonal recovery protocols for men seeking to restore reproductive health, optimize sperm parameters, and support natural hormone production. Every protocol begins with comprehensive hormonal, metabolic, and fertility testing, allowing treatment to be tailored to each individual's biology, goals, and timeline. Evidence-based strategies may include lifestyle optimization, targeted supplementation, and specialist-prescribed therapies where clinically appropriate.
This is a sensitive area, and it is treated with the seriousness it deserves. We start with a clear picture of your hormones and fertility, then build a plan around your body and your timeline, whether that means protecting your fertility while on testosterone or recovering it after coming off. It is quiet, unhurried, judgment-free care, and every step is explained so you always know where you stand. We stay honest about what is and is not possible, no promises, just proper medicine and a clear plan.
Specialist counseling and education on anti-aging, focused on peptide therapy and NAD+ protocols, alongside the nutrition, training, and lifestyle that support them. We teach you what these protocols are, how they work, and how they're used. Education and counseling only. We do not sell or supply peptides, NAD+, supplements, or any products.
This is guidance, not a sales pitch. There is a lot of noise around peptides, NAD+ and anti-aging, and much of it is marketing. Our job is to cut through it with honest, specialist-led answers on what these protocols are, how they really work, what the evidence does and does not show, and where the genuine risks sit, alongside the training, nutrition and sleep that do most of the work. We do not sell or supply any products; we simply help you make safe, informed decisions.
The economic and clinical unit of the practice. A specialist-led intake, full biomarker workup, and a written individualized 12-month protocol covering hormone optimization, metabolic medicine, advanced diagnostics, and education on peptide and longevity science, with quarterly biomarker reviews and telemedicine follow-up built in. Designed for the patient who wants continuous care, not a one-off consultation.
It is a full year of us looking after you properly, not a one-off visit and a prescription. It begins with a proper workup and full bloodwork, a real look at your hormones, metabolism and where your health sits right now. From there our specialist, double board-certified in Internal Medicine and Endocrinology, builds a plan around you and what you want, whether that is getting your energy and drive back, losing weight, sorting out your hormones, or just staying strong and sharp as you get older.
The real difference is what happens after. Across the year we keep testing, checking in and adjusting, so the plan actually keeps working instead of stalling after a few weeks. It is proper, supervised medicine, not a shelf of supplements and crossed fingers, and you are never left chasing appointments. You have direct, discreet access to your doctor when you need it, in English or Dutch, by video, at home, or in clinic.
Most people put more care into their car than into their own body, and this is you deciding to change that. The people who commit to it tend to say the same thing, that they feel like themselves again, and it only gets better the longer they stay with it.
Comprehensive hormonal, metabolic and cardiovascular workups through vetted reference labs. Every protocol begins with data, not guesswork.
Everything starts here, because you cannot fix what you have not measured. We run a genuinely thorough workup across your hormones, metabolism and cardiovascular health through vetted labs, and then a specialist actually reads it, in context and against how you feel, rather than waving through a few numbers as normal. That interpretation is where the value lives, and it is what turns a page of results into a real plan. It is the honest starting point for everything else we do.
Discreet, specialist-led prescriptions for expats and visitors who need to start or continue treatment on the Costa del Sol, or anywhere in Spain by video. Run out of a medication, left a prescription at home, or need a hormonal or metabolic issue handled properly while you are here? It is reviewed and issued by a double board-certified specialist, in English or Dutch, by video, at your residence, or in clinic. It starts with a short consultation, so every prescription rests on a specialist's judgment.
This is the opposite of a faceless online prescription form. You speak with an actual specialist, double board-certified in Internal Medicine and Endocrinology, who reviews your history and your reason for the medication before anything is issued. It exists for the situations that come up on a trip: you have run out of your regular medication, your hormone or thyroid treatment needs continuing, or something has come up that you would rather handle privately and quickly than sit in a public clinic for. Everything is done discreetly, in English or Dutch, by video, at your hotel or villa, or in clinic, and often the same day. Every prescription follows a proper consultation and the physician's clinical judgment, the same standard our long-term patients receive. For anything urgent or an emergency, always go straight to a hospital or call 112.
Facing surgery in a health system you do not fully know is one of the biggest decisions you will ever make. We help you choose the right surgeon for your specific procedure on first-hand clinical insight, not marketing, and stay alongside you from the first question through your recovery. Independent by design: we do not operate, and no surgeon pays us to be recommended.
It starts with a private intake where we go through your diagnosis, your records and your questions. If the real question is whether anyone should operate at all, we give you an honest, independent second opinion first. When surgery is the right path, we identify the surgeon whose hands genuinely fit your specific procedure, arrange the consultations, translate the options and trade-offs into plain language, and stay involved through the admission and your recovery. One physician, in English or Dutch, standing between you and a high-stakes decision in an unfamiliar system.

“Best Endocrinologist for weight loss and improved body composition.”
Lianne Nicole Muller, Google review
“Best sports endocrinologist in town”
Joel Amador, Google review
“I started working with this endocrinologist to help with weight loss, and the results have gone far beyond the scale. The weight I’ve lost has significantly improved my kidney function, which has been a huge relief. What stood out most was how available he was always ready to answer questions and explain the plan clearly. That level of support gave me real confidence and a lot of peace of mind throughout the process.”

From the middle of life onward, muscle, bone, recovery and the hormones that govern them drift a few percent a year. Nothing announces it. It reads as a busy season, a slower week in the gym, a shorter temper. By the time it is loud enough to interrupt you, the easiest decade to act in has already been spent.
A ten minute appointment. One number, read against a population average, and the word normal doing the work of a diagnosis. The years pass either way. What is straightforward at fifty is expensive at sixty, and bought back at seventy only in part.
The same years, read by a specialist who measures what actually matters and reads it against you, not an average. Strength that holds. Sleep that restores. A body that keeps pace with the life you built. Not a promise of youth, the compounding return of starting early and doing it properly.
Knowledge, guidance, experience, and a network of the finest specialists in Spain.
Independent. No investors. Answering to no one. First, do no harm.
