Our strength lies in our people — from top medical professionals to research experts, clinic staff, marketers, and leadership. Together, they shape a holistic experience built on trust, science, and care.

I have been with AYUN since day one – when it was little more than a bold vision. Initially as investor and sparring partner, I helped shape its beginnings; today, I lead AYUN as CEO and Chairwoman, driving its growth and evolution. With years of experience building and scaling longevity ventures, I bring expertise in strategy, leadership, and operational excellence. My mission is to make preventive medicine tangible and actionable, empowering people to take responsibility for their health and longevity. For me, healthcare is not just about reacting to illness – it's about equipping people early on with knowledge, tools, and confidence to stay healthy for life.

As a gynecologist at AYUN, I combine years of experience in prenatal diagnostics, hormonal therapy, and fertility medicine with the latest findings in longevity research. Women have different health needs than men – hormonally, biologically, and psychosocially – yet these differences are often overlooked. My mission is to ensure women are heard, understood, and treated individually. I tailor prevention, therapy, and counseling to each phase of life – for medicine that supports women's long-term health, performance, and resilience.
As a scientist and entrepreneur, I've always believed in the power of innovation to improve lives – AYUN made that belief deeply personal. What I thought was a routine check revealed a rare heart condition. Though asymptomatic, early detection allowed me to act and prevent future complications. That's the strength of AYUN. As Head of Operations, I combine my background in biomedical engineering and venture building to ensure our mission is executed with the highest quality.

I love good food. With ambition and scientific curiosity, I connect enjoyment with evidence-based nutrition to improve health on both metabolic and mental levels. My focus lies in the gut microbiome – I continuously expand my knowledge to understand how to optimally nourish it. For long-term change, I believe in intuitive eating without forbidden foods. My experience shows that nutrition can be healthy, delicious, and practical.

My path into nutrition counselling was anything but linear. After completing my studies in Belgium, I joined Emirates as a flight attendant and travelled the world. The intense working hours, irregular rhythms and life across time zones quickly showed me how essential nutrition and movement are for our wellbeing. From these experiences, a growing fascination for health and nutrition emerged. What began as a personal interest evolved into my professional passion and eventually led me to study nutritional sciences. It’s important to me to show people how profoundly nutrition influences both physical and mental health – in prevention as well as in therapy. I work evidence-based, practical and without strict restrictions. Sustainable change happens when nutrition tastes good and naturally integrates into everyday life.
As Clinic Operations Manager at AYUN, I merge my passion for longevity with a strong commitment to operational excellence.

Seeing the progress our clients make through early intervention and advanced therapies confirms my belief: those who invest consciously in their health today create the foundation for vitality and fulfillment tomorrow.
I studied General Medicine and Surgery in Mexico and gained several years of clinical experience both in Mexico and India. This international medical work has given me broad insight into different healthcare systems, disease patterns and approaches to patient care. However, my path has been shaped most profoundly by my own long-standing health journey. It motivated me to explore the root causes of various conditions in depth and helped me understand how essential a holistic, preventive approach is for achieving lasting health and a high quality of life.
