  • Professional, ethical, calm and knowledgeable

    “Dr. Thomas Berg has made my new health journey very comfortable and amazing. He was patient enough to listen and answer all my questions, responded immediately when I communicated and calmed me down whenever I panicked because of a health reaction. He is a professional, ethical, calm and knowledgeable doctor.”

  • “The best decision I could have made”

    “This clinic is absolutely amazing. When I came in for my consultation the first time, I had very little faith in the whole thing because I had spent a lot of money in another clinic before and was basically “Botched”. The ladies at the reception were amazing. And then I met Dr. Thomas Berg – who listened to me, encouraged me and gave me hope, as it was quite hard for me to open up about what I had gone through at the previous clinic. To cut the story short, I have had 3 corrective procedures done by Dr. Thomas Berg, and I feel like a million bucks. My results are amazing, more than I had expected, I feel great, and love myself now more than I have ever done before. I enjoy being ME now. The aftercare was wonderful too. Thomas called to check up on my progress after surgery. The thing I have loved about Thomas is he will not let you spend your money on what he thinks is not necessary, AND am glad I listened to him, he has a way of making his patients feel good about themselves (that’s what a good doctor does). Walking into this clinic was the best decision I could have made for me, AND I feel lucky to have met such an experienced and gifted surgeon. If you are considering any kind of procedure, this is the clinic to go to, don't waste your money somewhere else.”

  • Breasts with a very nice, natural shape (implants and breast lift)

    “In January 2020, I underwent breast surgery. My breasts has been a mental strain since puberty due to their asymmetrical shape. I was aware that my breasts would make it more demanding to get a nice result (have also breastfed several children), and therefore visited several surgeons in Oslo to be sure that the result would be as good as possible. After consulting with several surgeons, Dr. Thomas Berg was the doctor who gave the best impression of them all. He was patient, very nice, listened and took the time to explain to me the cause of my condition. He also had experience with operating on a tuberous breasts (tubular breasts). He really is a skilled and honest doctor! I chose a combination of implants and breast lift (Mastopexy). I was very well taken care of throughout the process, and felt very safe on the day of the operation. The service at Cosmo Clinic is truly impeccable, and the clinic itself is great, clean and modern! The result: breasts with a very nice, natural shape. I am incredibly happy with the service and quality of Thomas' work - I really could not have been happier! I will definitely choose Cosmo Clinic again if I want to do more cosmetic surgery in the future, and can highly recommend Thomas!”

I have no words for how good the treatment I received from the surgeon and the staff working there. Safe, professional and positive people. Good follow-up from start to finish with 24 hour availability on telephone if there should be an acute crisis or questions after the operation, a good security.
