Reza J. Karimi, MD


I want my patients to know that if they have a condition that requires surgery, I’m going to get them through it as safely as possible, using the most minimally invasive techniques available.


Dr. Karimi is one of only a few neurosurgeons in the country with advanced fellowship training in open microvascular neurosurgery and endovascular neurosurgery. This subspecialized training enables him to successfully perform some of the most highly complex and intricate surgical procedures, including using the latest techniques to treat brain aneurysms, vascular tumors, stroke, and vascular malformations of the brain and spine.

A lifelong New Jersey resident, Dr. Karimi has a single goal when treating patients: Avoid surgery whenever possible, and if surgery is necessary, provide the safest, most effective approach. To ensure he meets that goal, he views patients like family and he treats them like family, never recommending treatment that he would not recommend to his own relatives.
