Dr. Cohen is among a select group of surgeons in the country who focus on the medical and surgical management of nasal and sinus disorders and has special expertise in minimally invasive surgical options to treat patients with these problems. Dr. Cohen’s passion for minimally invasive surgery has not only deemed him an expert in Minimally Invasive Image Guided Sinus Surgery (MIGSS)™ and Balloon Sinuplasty™ but also has named him Director of the Minimally Invasive Thyroid and Parathyroid Surgery Program at West Hills Medical Center, the only program of its kind in the San Fernando Valley and Thousand Oaks regions.

Dr. Cohen obtained his B. S. in Neuroscience after graduating summa cum laude, Phi Beta Kappa from UCLA and was awarded acceptance to the prestigious David Geffen School of Medicine at UCLA, a top 10 school. He gained his M. D. degree after four years with honors and a thesis in Head and Neck Surgery and subsequently was recruited to pursue a Head and Neck Surgical Residency at UCLA Medical Center, a top 5 program in the country. While at UCLA Medical Center he completed 2 years of general surgical training and 4 years of specialized ENT/head and neck surgical training. During his training at UCLA, he rotated to Harbor General County Hospital, Olive View Medical Center, Wadsworth Veteran’s Hospital and Children’s Hospital of Los Angeles (CHLA). He completed his residency with a one-year Chief Residency in Head and Neck Surgery at UCLA Medical Center, where he emphasized in minimally invasive techniques for the surgical management of nasal and sinus disorders, thyroid and parathyroid diseases and head and neck tumors.

He is a Fellow of the American College of Surgeons and is board certified by the American Board of Otolaryngology/Head and Neck Surgery. He also maintains a full membership in the American Academy of Facial Plastic and Reconstructive Surgery (AAFPRS) and the American Rhinologic Society (ARS) .
