Dr. Cohen has made it his life’s work to meticulously study and advance the art of brain surgery.

He is known for taking on the most difficult surgical cases and delivering the most optimal results. He specializes in the diagnosis and treatment of a variety of brain tumors and other diagnoses including gliomas and meningiomas, acoustic neuromas, pituitary tumors, arteriovenous malformations, trigeminal neuralgia, and hemifacial spasm.

His surgical philosophy focuses on efficient and minimally invasive surgery; this technique protects normal brain and the patient’s function during surgery. For example, he developed endoscopic techniques that allow the surgeon to remove a brain tumor, via the nasal passage, without opening the patient's skull. He also has refined fluorescent technologies that cause a brain tumor to "glow," making it possible for the surgeon to remove the tumor effectively.

Dr. Cohen is a relentless innovator, committed to technical excellence and achieving the best possible outcomes for his patients. This manifests in his many roles as a surgeon, professor, researcher, author, speaker, mentor, and pioneer. He founded one of the country's most competitive neurosurgical tumor/skull base surgery fellowships and has served as a role model and mentor to hundreds of students, residents, and fellows since 2007.

His career signature has been serving as the founder and CEO of the Atlas Enterprise and its flagship organization, the Neurosurgical Atlas, where he inspires thousands of neurosurgeons to achieve technical excellence and peak performance in the operating room. Each product in the Atlas Enterprise family pushes the boundaries of how surgeons prepare, perform and collaborate. Many surgeons and physicians around the world depend on the Neurosurgical Atlas, known as “the Bible of Neurosurgery,” for the care of their patients. He is continuing to develop creative and innovative surgical techniques and resources that empower the global healthcare community to revolutionize patient care. This is his legacy.

Dr. Cohen has a profound drive and passion for uncompromising excellence. Those close to him say he is “a virtuoso of his craft.” Born in Tehran, Iran, he overcame impossible odds to immigrate to the United States. He later lost his treasured 12-year-old niece to a malignant brain tumor. These personal stories, and the thousands of patients’ lives he has transformed, have ingrained in Dr. Cohen a deep sense of empathy, humility, and bravery. He instills the courage required for patients, their families, and fellow surgeons to prevail during the most challenging moments in surgery and health crises never faced before.

“The pursuit of technical excellence in neurosurgery is a passion and not a job. My philosophy has always been to do the best anyone can, rather than do the best I can.”
