About Me

Longevity Systems Consultant

Combining my clinical experience with longevity science, business development and R&D strategy, I provide systems consulting to clinics, hotels, health companies and organizations. What matters to me is turning a good health service into a system that actually works, rather than leaving it as a set of isolated interventions.

2015 — 2020

Baskent University - Nutrition and Dietetics

I studied Nutrition and Dietetics at Baskent University between 2015 and 2019 and started my career on the clinical side. As a managing dietitian at Ali Sahan Polyclinic in Ankara, I managed nutrition processes and contributed to planning combined treatment protocols with non-invasive weight loss devices.

Specialization

Clinical Nutrition Protocols

Through US-based training, I specialized in developing nutrition protocols for infusion-based applications and combined my clinical nutrition knowledge with the scientific foundation in this field.

Rene Clinic · 2020 — 2024

Longevity Department Setup

Moving to Istanbul, I spent four years at Rene Clinic taking an active role, together with Prof. Dr. Reha Yavuzer, in setting up and managing the longevity department. I worked on integrating the longevity concept into the clinic's existing structure, designing patient journeys and process flows, and creating package structures, protocols, and team training.

Prof. Dr. Osman Müftüoğlu · 2024 — 2025

Yasasin Hayat Clinic

At Yasasin Hayat Clinic, where Prof. Dr. Osman Müftüoğlu served as health director, I provided longevity-focused clinical nutrition consulting. I was also responsible for process standardization and coordination of the complementary applications (IV/IM support) department. I planned nutrition programs focused on metabolic health, energy, and immunity, and structured patient evaluation workflows.

R&D · 2025

Compounding Production and Health R&D

I served as general coordinator at one of Turkey's leading compounding production and health R&D centers. I coordinated compounding product and protocol development processes based on clinical and field needs, and planned personalized protocol designs with physicians. I also built the physician CRM infrastructure and managed a professional network of more than 4,500 doctors along with its analytics processes.

Marga Wellness · 2026

Clinic Operations and Hotel Wellness Integration

As clinic manager and business development lead of Marga Wellness's Istanbul structure, I managed clinic operations, sales processes, guest experience, hotel integration and the structuring of longevity services. In line with the growth targets of the Istanbul, Izmir and Baku locations, I turned longevity check-up flows, wellness protocols and membership models into measurable and commercially sustainable structures.

Today

Longevity Systems Consulting

Today I work on a project basis: longevity systems consulting for private hospitals, hotels, doctor clinics and wellness centers; product strategy and protocol development consulting for pharmaceutical and R&D companies; and longevity-focused nutrition and lifestyle consulting for individuals and organizations. I also develop new longevity and wellness projects with Marga Wellness as a business development and strategic partnerships consultant.

I position myself not as "just someone who writes diets" but as a partner who touches the clinic's operational system, financial sustainability, and patient experience.

Frequently Asked Questions

About Longevity Consulting

The most common questions about longevity consulting, clinic setup processes, and how I work.

What is a longevity consultant and what do they do?

A longevity consultant is an expert who designs programs and structures that support healthy aging by combining nutrition, lifestyle, and clinical systems in light of scientific evidence. With my background in clinical nutrition, clinic operations and R&D strategy, I provide longevity department setup for clinics, hospitals and hotels, product strategy for health and pharmaceutical companies, and longevity-focused nutrition and lifestyle consulting for individuals and organizations.

Do you also work with hotels and wellness centers?

Yes. For hotels and wellness centers I build longevity models where spa, fitness, concierge and clinical services meet in a single guest journey — covering longevity check-up flows, package and membership structures, team coordination and the revenue model.

At Marga Wellness I led clinic operations and business development within its Istanbul structure, working towards the growth targets of the Istanbul, Izmir and Baku locations. Today I consult in the same area on a project basis.

What does setting up a longevity department bring to my clinic?

Patients now demand not just disease treatment but healthy aging, energy, and quality of life. A longevity department provides a structured answer to this demand while creating a new service line and revenue model for the clinic. My setup consulting covers target audience analysis, service menu, patient journey design, protocol frameworks, team training, and the financial model end to end.

How long does a longevity department setup take?

The duration depends on your clinic's existing infrastructure and the intended scope. The process typically proceeds through analysis, design, pilot, and go-live phases; team training and documentation run alongside these phases. In our first meeting we draw up a realistic timeline based on your current structure.

In which cities and countries do you work?

I am based in Istanbul (Nisantasi); I work on-site with clinics across Turkey, and on-site or remotely (online) with organizations abroad, especially in Europe. Corporate training and individual consulting can also be conducted online.

How does individual longevity consulting work?

The process starts with a comprehensive initial assessment, followed by a personalized nutrition and lifestyle plan based on your metabolic health and goals, and regular follow-up sessions.

All medical applications are conducted under physician responsibility; I support the process in terms of nutrition and lifestyle.
