Sarah - Bristol Clinic


The service that I received was outstanding. I am pleased with the whole process from start to finish. Debbie has been very supportive with booking appointments. Marion was very knowledgeable around the routine and the after care. I couldn't fault The Harley Medical Group. Maidstone Group was 100%. Allwin Gnanajebamani was very understanding with my needs to get the outcome I was after, he spoke about all the options and how he would action the surgery. Again I couldn't fault him. Thank you to the Harley Medical Group.

Lawrence - Maidstone ClinicRhinoplasty (Nose reshaping)


Every member of staff I met was very helpful and friendly. The staff were more than happy to stay and chat, the nurse even gave me a hug before I went down to surgery! They are all also very professional. I went to a consultation elsewhere before Harley and found the staff very 'sales' but when I came to Harley I felt the staff were very caring, especially as they are trained nurses and not working on commission. I have recommended my friends to this company and also my partner who has now booked in to have fillers in a couple of weeks. Really can't thank the staff and especially Allwin for making me so happy and confident with my new look, and can't recommend Harley Medical enough! Thank-you, thank-you, thank-you!

What a pleasant experience! Going in I was quite nervous but the staff at the clinic, Highgate hospital and Mr G were incredible. I am so pleased with my results from breast augmentation and would recommend Harley Medical Group and Mr G to any of my family or friends who might be thinking about it.

I had vaser lipo on four areas and i have never been so happy in my life. The results are just everything that I have ever wanted, if I were to ever have any procedure done in the future I would go to harley street instantly. I have felt at ease every time i visited the clinic all I can say is Dr.Allwin did an amazing job he is the best! 

Sitara - Watford Clinic


Dr Allwin is without doubt a brilliant surgeon who takes the time to listen to any questions and concerns you have and is honest and quick to put your mind at ease. Just perfect.

Amy - Cardiff Clinic


The day of my surgery I was treated amazingly. I could not fault the staff, Mr Allwin is a amazing Surgeon! he has changed my life! you might think dramatic but imagine waking up and smiling everyday because i do!! 

Elizabeth - Northampton Clinic - Breast Augmentation


My surgeon was fantastic and has a clever way of helping you make the right choice for you. If I had just told him what to do, I would have not been half as happy with the results. He spent lots of time trying different sizes with me until I felt I had a verilsion of the perfect breasts for me... Now I have them for real and could not be happier. 

Rebecca - Maidstone Clinic


I would highly recommend your services to any of my friends and family! You provide a very professional service. My surgeon Allwin delivered amazing results, he was very caring and so professional. I felt in safe hands right from the start. He is very confident and realistic, and I haven't been disappointed. He has given me my waist back after having two children. I am forever grateful, being in safe hands was my first priority and Allwin was the best choice. His team was very caring and the hospital was absolutely top class. Thank you to all.

letter from a patient:

To whom it may concern,

I had always been unhappy and a little self conscious about the size and shape of my nose. It was quite prominent and more noticeably, the tip bent to one side due to a deviated septum

Having grown up in the sixties, I am not of the generation that would normally opt for cosmetic surgery

In my forties, I found that one side of my nose had become totally blocked, so consulted my GP, he advised surgery performed by an NHS ENT Specialist

After the op, the surgeon advised me that my nose had been badly broken early in my life ( probably as a result of my fondness for boxing as a youngster) and that he had removed some of the septum to restore function and suggested I consult a cosmetic surgeon to perform a more complete and beneficial procedure

Having consulted several cosmetic surgeons I met Mr Allwin Gnanajebamani, he listened and importantly understood that I did not want a radical change in my appearance.  He also openly advised that I may need a revision after the initial procedure, as my nose had been damaged.

I had the first op in June 2014. The hospital, staff, care and efficiency were truly excellent.

My nose healed and I was happy with the result. It was slightly less prominent and the tip more symmetrical.  I had the usual follow up visits to the clinic to check everything was healing well, which it was.

After approx ten months I had a final review with Mr Allwin Gnanajebamani who immediately commented that he would like to perform a revision to improve the final appearance.  I agreed to this.

The Harley Medical Group did exactly what they promised. I had the revision in September 2015 and the final result is amazing. My nose is straight, less prominent and the airways clear.

Very importantly, there were absolutely no further expenses for the revision, not even a standard admin fee at the hospital.

Once again the care was excellent, including the follow up appointments at the clinic.

The result is so much better than I could have hoped for.

THMG do what they say they will do, over and above the normal expectations.

Thank you Mr Gnanajebamani and all at The Harley Medical Group.

Best Wishes
