Optimal Health, Optimal Life!

Hello! My name is Dr Houda Ounnas. I am an experienced private GP with specialist interest in proactive health for professional and executive women, whom I call

"city girls". I have studied several subjects in addition to general practice, in order to be able to offer busy women a complete health package, where all their health needs are discussed in one appointment, in one stop clinic with one experienced female doctor. The aim is to save them time and leverage everything modern science and medicine has achieved to help city girls reach the optimum health and in turn optimum quality of life they deserve.

Ounnas Medical London is a private GP + clinic, in Harley Street, London. However, you do not need to be in London to access all our services, as we also offer online video and telephone consultations. We subspecialise in Health Checks, Preventative Medicine, Aesthetics, Mental and Emotional Health and Occupational Health. That means under one roof we can help you feel better, look better and live better. All elements can be offered separately or amalgamated with general practice. It is a service for individuals who value their health and quality of life but are too time poor for back and fourth doctors appointments.


Ounnas Medical aims to offer one worthy appointment, with one experienced doctor, in one setting. We operate from inside the Phoenix hospital in Harley Street, which means we have on site accees to their state of the art laboratory, scans, pharmacy and referrals if needed, all under one roof. Furthermore, we have friendly patient co-ordinators (health concierge service) who co-ordinate it all for you, making looking after your health easy and hassle free.

You can have your blood tests, smear test, STD screen, mammogram etc all in one place and one day of need be. 

We are based on the principle of optimum health care. We are a one stop clinic, whereby problems are treated from the roots and used as an opportunity to prevent recurrences and optimise your health in the long run as well. We serve both your present and future self.

The appointments are 1 hour or 30 minutes, nothing less. This is longer than those offered by anyone else in London. The aim is that you build a relationship with one doctor who has an opportunity to study you holistically, considering all aspects of your health. It is a time saving and cost effective clinic in the long run, because your problems are understood and solved efficiently and in harmony.

We ensure your experience with us is exceptional from the outstanding doctors skill mix to our consulting rooms in Harley Street to the customer experience. Ounnas Medical aims to make looking after your health an enjoyable and time worthy experience. Get in touch today and start enjoying a healthier, happier lifestyle!
