Dr. Reza Karimi is simply the best! 2 years ago he pointed out the blockage in my husband’s vertebral artery that no other doctor had told us about. The stent he implanted continues to keep the blood flowing. His expert advice and skill are invaluable. We are fortunate to have found him and are eternally grateful to him.

Dr Karimi: Very professional and great bedside manner. Was able to get a follow up appointment as recommended per the discharge paperwork. His team also assisted with other doctor recommendations for appointments not easy to secure. Just want to say thank you to him and his team.

Dr Karimi is everything you want in a doctor who is going to work on your brain! He is kind and patient and reassuring but most importantly he is a brilliant practitioner with years of experience and knowledge. He took care of an aneurysm I had which was an incidental finding due to tests and the minute I met him I knew I was in competent and confident hands. Working with his staff is also a comfort when you are feeling some anxiety about any procedure. Let Dr Karimi ease you through any medical decision regarding aneurysms and related issues and you will have peace of mind throughout the process. Thank you, Dr Karimi, for your expertise and kindness!
