For individuals navigating highly demanding leadership, corporate, or public roles, time and privacy are paramount. Standard clinical frameworks, while delivering excellent medical care, can be logistically prohibitive for the ultra-high-net-worth (UHNW) individual. Appointments are rigid, communication is often siloed, and the nuance of managing high-stakes, public-facing lives is frequently misunderstood.
The Private Office provides an alternative structural model: a retained, concierge medical advisory service designed exclusively to offer extended clinical time, proactive health management, and absolute discretion.
We do not compromise on availability. To ensure the integrity of our response times, the depth of our clinical oversight, and the bespoke nature of our logistics, The Private Office is strictly limited to a maximum clinical capacity of two active Principals, families, or Family Offices at any given time.
While our wider clinical practice is widely recognised across the UK under the name ADHD Specialist—reflecting our foundational, industry-leading expertise in complex neurodiversity—human psychology is rarely singular. Through The Private Office, we deliver comprehensive, full-spectrum mental health care.
Dr. Stefan Ivantu, M.D., MRCPsych, and his multidisciplinary team are highly experienced in managing the vast majority of adult psychiatric conditions. We understand that our clients do not just want to manage an illness; they want to optimise their cognitive health. We specialise in the evidence-based treatment of:
This retained tier guarantees that we can dedicate the necessary time, immediate attention, and logistical agility required for highly complex, intersectional cases.
A Partnership Built on Shared Values, Intellectual Curiosity, and High Performance
Dr. Stefan Ivantu approaches psychiatric care not simply as the absence of pathology, but as the active pursuit of cognitive resilience and psychological optimisation. Beyond his extensive clinical background and Harley Street practice, his methodology is deeply informed by a multidisciplinary intellectual curiosity and a personal ethos of high performance.
A passionate advocate for healthcare sustainability and the ethical integration of technology, Dr. Ivantu actively explores the forefront of mental health innovation, including advancements in telepsychiatry and virtual reality. This forward-thinking clinical approach is meticulously balanced by a profound appreciation for history, precision, and craftsmanship. This is reflected in his lifelong captivation with the art of filmmaking, the engineering of high-fidelity audio equipment, the curation of antiques, and the tactile, deliberate discipline of manual lens and rangefinder photography.
Understanding the critical link between physical discipline, metabolic health, and cognitive resilience, Dr. Ivantu is an active basketball player and enthusiast of strategic PC gaming, who follows the rigorous analytics of U.S. basketball leagues. He is currently advancing his athletic pursuits by training to become a certified tennis coach.
Coupled with his deep interest in the philosophical intersections of Eastern and Western cultures, this diverse mindset allows Dr. Ivantu to intrinsically understand the discipline, strategic focus, and complex personal architecture required by global leaders to operate at the peak of human capability.
We provide deep, unrushed clinical assessments to manage the psychological toll of elite leadership and wealth management.
We adapt entirely to the schedule and location of the Principal, ensuring absolute continuity of care without the friction of a traditional waiting room.
Complex health requires a unified, precise, and rigorously evidence-based approach. We leave nothing to guesswork.
Privacy is not just a promise; it is structurally engineered into every facet of our practice.
The traditional healthcare model is inherently reactive. A retained medical model shifts the paradigm from reaction to prevention and optimisation.
For the entrepreneur, the CEO, or the prominent family, the cost of untreated executive burnout, impulsive decision-making driven by unmanaged ADHD, or severe sleep deprivation is not just personal—it is structural and financial. The Private Office acts as an elite insurance policy for your most valuable asset: your mind.
By retaining Dr. Ivantu and his team, you are securing a dedicated medical partner who deeply understands your baseline, your corporate pressures, and your family dynamics. When a challenge arises, you do not need to explain your history to a new clinician; we are already fully briefed and ready to execute an evidence-based clinical strategy immediately.
Retained care means that a family or individual pays an annual or quarterly retainer fee to secure priority access, expanded clinical time, and comprehensive logistical support from Dr. Ivantu. It ensures that our practice remains low-volume and high-touch, allowing for a level of dedication impossible in standard high-volume private clinics.
Yes. We understand that UHNW individuals rely on their teams to manage their lives. With your explicit, documented medical consent, we seamlessly integrate our logistics (scheduling, invoicing, non-clinical coordination) with your Chief of Staff or Family Office Director to ensure a frictionless experience.
Because availability is exceptionally limited, the onboarding process is thorough. It begins with a preliminary, non-clinical briefing between your representative (or yourself) and our Practice Manager to ensure structural alignment. If suited, this is followed by a comprehensive, multi-hour psychiatric evaluation by Dr. Ivantu to establish a clinical baseline and design a bespoke roadmap for care.
Absolutely. Dr. Stefan Ivantu is a fully qualified Medical Doctor (M.D.) and a Member of the Royal College of Psychiatrists (MRCPsych). While he is highly sought after for his expertise in neurodiversity, his psychiatric training and ongoing clinical practice encompass the full spectrum of adult mental health disorders, including complex mood disorders, anxiety, and trauma.
We adhere strictly to the confidentiality guidelines set by the General Medical Council (GMC) and UK data protection laws (GDPR). Furthermore, we are accustomed to working with high-profile individuals and operate with an elevated tier of structural privacy. We are happy to review and sign bespoke Non-Disclosure Agreements (NDAs) prior to any clinical engagement.
To maintain uncompromised clinical excellence, availability for The Private Office is strictly capped.
To Initiate a Private Discussion:
Initial enquiries are handled with the utmost discretion and urgency. We invite Principals, Family Office Directors, Chiefs of Staff, or designated legal representatives to arrange a preliminary, confidential briefing with our Practice Manager. This initial step allows us to discuss logistical requirements, structural expectations, and clinical suitability before formally engaging.
