I found him very informative and he grasped my rather complex medical condition very quickly. His advice was clear and concise and I know exactly what to do next.


Dr.Rajeswaran is an extremely competent physician and diabetologist. I have been associated with him professionally for the last 17 years and I find his work extremely good. He has extensive experience also in the management of obesity related problems and I has found his management very rewarding for the patients as well.


I have found the sessions attended useful, informative and personally challenging. I have succeeded in my goal to lose weight and have maintained for nearly 3 months. This, I believe, is due to the factual evidence based content presented within the progrm. Dr Raj and his team are highly motivated, supportive and professional and as a result I have recommended the program to many f my colleagues and friends.


When I find decided to loo for a weight loss programme I wanted a medically controlled scheme. After searching the internet I found The London Obesity clinic which is a division of Simplyweight. I emailed the clinic and a member of staff rung me to arrange a telephone call with Dr Raj (Rajeswaran). This was start of a wonderful life changing experience. I went to see Dr Raj at the Harley Street clinic and from the start he was supportive and encouraging. He explained that the programme took a holistic approach to losing weight, the 100 on line programme consists of 3 elements - Simhappy - a daily motivational video, Simportion - recording you daily food allowance and Simactiv - a daily exercise dvd plus additional on line support and regular one to one appointments with Dr Raj. Dr Raj and his motivational coach have been inspirational in changing my life. I have lost to date over the last year 6 stones, I am happy and healthy. This is due to Dr Raj's and his team's encouragement which is still part of my maintenance programme. I would encourage anyone who has struggled to lose weight to contact Dr Raj through the clinic.


I have found Dr Raj, to be very knowledgeable, informative, supportive, and having a clear direction in his approach to my situation, from the very first consultation, through the many follow-up consultations, he has already helped my start to solve my situation, and I have found very positives ways to move forward, something I had been unable to do in the past successfully. He utilises experts from other areas and helps to bring it together in one clearer picture, enabling me to see a way to see a longer term future for me my family and my health.


I wish to recognise Dr Chinnadorai Rajeswaran being an excellent physician and for his exceptional dedication. In desperate times of January this year (2007) I was trying to find a doctor that specialised in my condition (Addison's Disease) that would listen to me, understand me, work with me and be able to help support my journey in regaining some life back and improve my overall health and wellbeing. It has not been an easy journey, but with Dr Raj and his team of excellent staff, particularly his Clinical Nurse Specialists (Simon and Ruth) he has been compassionate, supportive and motivational to date and I am getting the results I have longed for. Being in the health care profession myself, I knew what I wanted and what I needed so I had an expectation in Dr Raj. Well he has surpassed all my expectation! If you want a true professional who is understanding, supportive and who listens to you then Dr Rajeswaran is your man! I highly recommend him as a person and an excellent physician.


Dr Raj is an excellent physician He is compassionate and is motivating his patients to achieve a healthy life style He and his team has holistic approach for physical and emotional health
