Patient Testimonials


Even though we knew Dr. Marmureanu is extremely busy, we insisted to choose him for my father’s surgery because we had only heard good things about him as a medical professional. Our wait was definitely rewarded and my father’s difficult lung surgery was a success. Dr. Marmureanu made sure to provide us with a complete surgical plan and to explain the risks of the procedure thoroughly. He is a very knowledgeable, confident and skilled surgeon and I’d recommend him to anyone who needs cardiothoracic surgery.

In 2014, I underwent video-assisted surgery for lung cancer. I cannot thank Dr. Marmureanu enough, for he did a great job and really saved my life. The surgery was quite difficult but I couldn’t have been happier with the outcome. My incisions were very small and I barely felt any pain after the surgery. Dr. Marmureanu was also very attentive during my follow-up visits, making sure my recovery was going well. I highly recommend him!

He is one of the most talented and kind surgeons I’ve ever met. Dr. Alexander Marmureanu performed a very difficult coronary artery bypass surgery on my mother 3 years ago and we are incredibly grateful to have come across such a wonderful surgeon. Her condition has improved significantly all thanks to Dr. Marmureanu’s remarkable skills and effort. Don’t hesitate to choose him and you will certainly not be disappointed!

Dr. Alexander Marmureanu is a gifted surgeon who treats his patients with utmost respect and compassion. I had to undergo valve replacement surgery in May 2014, which I knew could be a very risky procedure, and I was very lucky to have met Dr. Marmureanu. My surgery took nearly 4 hours and it was an absolute success. The debilitating symptoms I used to feel are practically non-existent today and I can finally enjoy a carefree life. If you ever need heart or lung surgery, definitely go to Dr. Alexander Marmureanu!
