"Dr. Kowalski is a wonderful doctor who is truly committed to dispelling any doubts and questions. My mother and I have been patients of Dr. Kowalski (both of whom have had bariatric surgery). His hands-on approach made me feel comfortable choosing a surgeon. He visits patients frequently during their stay at the clinic and always returns calls. He always calmly explains and answers many questions and concerns. He advises on what to focus on after surgery, what medications to continue taking, and what supplements to consider. If you are looking for a good surgeon, you have found him - Dr. Kowalski is a doctor you can completely trust. It is worth adding that I flew from the US for the surgery precisely because of his excellent reviews. If I had to choose a surgeon again, I would definitely choose Dr. Grzegorz Kowalski."

"The doctor removed a large cancerous growth from my grandfather. It healed very well; from a cosmetic point of view, there was practically no trace of the procedure. I also had an ingrown toenail removed that I had been struggling with for years (using splints and invisible miracles). Now, after the procedure, I have no more relapses! Highly recommend!"

"On November 22, I had a sleeve gastrectomy. The procedure was performed by a wonderful doctor, Dr. Grzegorz Kowalski. Everything went according to plan, and two days later I was discharged home. A month later, my weight had already decreased by 16 kg and continues to decrease. I am very grateful to the doctor for helping me start a new life. I thank him from the bottom of my heart."

"I recently had the pleasure of undergoing a buttock reconstruction procedure performed by Dr. Mazan following a traumatic injury. The procedure involved lipotransfer, and the results were incredible after just one session. Dr. Mazan not only possesses exceptional skills but also a vision that allows him to strive for perfection in every detail. I am very pleased with the results and can confidently recommend Dr. Mazan to anyone looking for a professional and talented plastic surgeon."

"In July, Dr. Mazan performed a calf implant procedure on me due to visible asymmetry and underdevelopment. My calf before the procedure was bone covered with skin, with little fat, and no muscle. My calf looks different after the procedure… better. So much so that once the skin and tissue have stretched a bit, I'll consider a second implant."

"A very empathetic professor. I felt like I was talking to someone I knew well. I feel cared for and calmer because I know what to do next in my illness. This is exactly what I was looking for: peace after many months of stress and suffering."
