  • From the very first meeting with Mr Alnajjar, he showed high standards of professionalism, was very attentive, answered my questions with so much compassion and knowledge and immediately knew what to do. It was a very troubling period for me especially going to other places and not getting the desired result. I can’t overemphasize how delighted I was getting the solution I needed and walking out fulfilled. Thank you so much and God bless you. You are exceptional!

  • Operation when exactly as described, if not better, and really pleased with the aftercare and recovery. Mr Alnajjar is an absolute professional with an eye for detail and protection and puts the patient first. Mr Alnajjar with over an above, for example calling me the day before surgery to check if I’d any last minute questions and then phone my first night home to check in. 10/10

    Verified patient
  • I recently underwent surgery with Dr. Alnajjar and I couldn't be happier with the experience. From the initial consultation, it was clear that the doctor truly understood my concerns. He asked targeted questions to get to the root of the issue and explained the risks and benefits thoroughly, allowing me to make a truly informed decision. The scheduling was incredibly accommodating, and the surgical outcome was perfect. I’ve had a quick recovery with no complications and minimal scarring.
