  • 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.
