Kamyar Assil, M.D. is an expert in pain management and has been a practicing physician for more than two decades.

Dr. Assil's interest in pain management developed when he was just a child. When Dr. Assil was seven years old, his father sustained a back injury while shoveling snow and was bedridden for nearly six months. Due to the lasting impression of this event, Dr. Assil developed interest in the human nervous system and pain control. He completed his honors thesis and undergraduate research on the nervous system, pharmacology of opiates and pain mechanisms. Since, Dr. Assil has published several research papers regarding those subjects.

He received a Bachelor of Science with honors in psychobiology from the University of California, Los Angeles (UCLA) and a medical degree from the University of Southern California (USC) Keck School of Medicine. Additionally, Dr. Assil is an active member of many related medical societies. He serves as a senior instructor for the Spine Intervention Society (SIS) and is a regular lecturer at USC's Department of Anesthesiology/Pain Medicine. Also a Qualified Medical Examiner (QME), Dr. Assil practices as an expert witness for interventional medicine and pain management.

Dr. Assil was one of the first fellowship-trained pain specialists in Ventura County, with formal training in pain management from State University of New York Health Science Center in Brooklyn, N.Y. He also completed a clinical fellowship and advanced training in interventional pain management at the Manhattan Center for Pain Management at Saint Luke's-Roosevelt Hospital in New York City, N.Y. Before joining Ventura Orthopedics, Dr. Assil was the founder and medical director of Conjeo Pain Specialists, Inc. in Thousand Oaks, Calif. for two decades.

With specializations in pain management, and working closely with other medical specialists and physical therapy, Dr. Assil focuses on targeting the source of pain –– treating everything from severe headaches, neck pain and nerve damage to herniated disks and lower back pain.

Dr. Assil is a sought-after practitioner, serving a variety of celebrities and local dignitaries. With a goal of improving the quality of life for his patients, Dr. Assil often seeks physical therapy, spine injections and other forms of conservative management before considering surgery as a viable option. He aims to focus on each individual from a physical, mental and spiritual level so his patients can ultimately function in normal day-to-day life.

A strong believer in the power of being physically active, Dr. Assil is an avid outdoorsmen. When he is not working with his patients to improve their quality of life, Dr. Assil is often found mountain biking or skiing. He currently resides in Thousand Oaks with his wife and three daughters.
