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.
