Andrew Michael Blumenfeld, M.D.

Dr. Blumenfeld is accepting new patients. Please call 760-631-3000.

Dr. Blumenfeld is director of the Headache Center of Southern California. As director, he has encouraged the development of a center addressing the multi-faceted needs of headache sufferers. These needs include acute care, educational programs and other specialty services. This comprehensive approach treats the whole person in a highly individualized manner and addresses the growing demand for one-stop treatment services.

Dr. Blumenfeld grew up in South Africa and graduated from St. Andrews College, South Africa, with a first class pass and distinction in mathematics. He attended the University of the Witwatersrand, Johannesburg, South Africa Medical School and completed a neurology residency at Johannesburg Hospital. In 1986 he moved to the United States and completed a neurology residency at the University of Massachusetts Medical School. Following this, he completed an EEG and EMG fellowship, also at University of Massachusetts Medical School.

He served as staff neurologist at Kaiser Permanente, San Diego from 1990 to 2004. As Chief of Neurology Service at Kaiser from 1999-2004, his unit was named a Neurotoxin Center of Excellence by Thomas Jefferson University and Jefferson Medical College. The Neurotoxin Centers of Excellence recognize excellence in neurologists and other physicians who specialize in headache management.

Dr Blumenfeld is a member of the American Academy of Neurology and the American Headache Society. He has published widely and has been an active researcher in headaches.

Dr. Blumenfeld has been a principal investigator for many research studies showing that Botulinum toxin type A, sold under the brand name Botox®, is an effective preventative therapy for headache in chronic migraine sufferers. He has treated more patients with Botox therapy than any other provider in the world and trains other physicians on this nationally and internationally.

In addition, Dr. Blumenfeld serves on the advisory board for Allergan, and has been a national speaker and consultant for Allergan as well as other well-known medical corporations: Pfizer, GSK, Merck, Posen, Zogenix, MAP pharmaceuticals, Forrest and Ortho McNeill. I believe in an individualized, patient centered approach that empowers patients to take control of their own health care. This requires that patients are fully informed about alternative therapies, and that physicians and patients make joint decisions about treatment, based on lifestyles and other medical factors. In this capacity, he regularly addresses national pharmaceutical meetings, medical conferences, continuing education seminars, and community events.

Board certified in neurology by the American Board of Psychiatry and Neurology, Dr. Blumenfeld currently holds active privileges at Scripps Memorial Hospitals (Encinitas and La Jolla) and Tri- City Medical Center in Oceanside.

An avid bicyclist, he participated in the Race Across America in 2003 and 2004. He also enjoys running and spending time with his family.

This experience, allowed him to stratify both knowledge and expertise in treating general neurology patients as well as continuing to use the skills he attained during his epilepsy fellowship by doing prolonged and routine EEG monitoring. He also was able to continue other skills by doing EMG/NCV's, sleep studies and Botox therapy. He was also able to continue to utilize his skills in the outpatient and inpatient settings including treatment and work-up of stroke.

He is an active member of the American Epilepsy Society, American Academy of Neurology, and American Clinical Neurophysiology Society. Dr Choudry works diligently to be an advocate for his patients. He believes in taking a thorough history, which not only allows him to make a more accurate diagnosis but often can be a cost saving measure for the patient.

Jay Rosenberg, M.D.

Dr. Rosenberg is accepting new patients. Please call 760-631-3000.

I have practiced neurology 29 years at Kaiser Permanente and 9 years with the Neurology Center. Over this period of time, my medical experience has been extensive and I consider it a privilege and honor to be a physician. I have faced head on the medical revolution as it pertains to the doctor patient relationship and economic reimbursement. Being the first chief of neurology and a founding member of the Kaiser Permanente group in San Diego, the bureaucracy of System Medicine at times was very challenging but I never lost sight of the fact that my patients were my patients. I continuously advocated for my patients even it if meant that I had to place individual patient needs ahead of the systems concern.

At the very beginning of my career, "Neurology" was just emerging from a "diagnose and adios" mentality and transitioning to an aggressive treatment approach. Throughout my career I have considered symptom management as one of the foundations of aggressive therapy. Now that we have an extensive armamentarium of many potential successful disease interventions, we can approach neurological issues with the confidence to achieve true "disease management" (treatment interventions and symptom management with emphasis on improving and maintaining quality of life).

My background is unique in that I grew up in a family where my father was a psychoanalyst and my brother was an autistic savant with seizures. I suffered with an orthopedic problem that warranted some 40 operative procedures before the age of 21. I married a wonderful woman and with her raised two children. This was despite her long-term struggle with multiple sclerosis and her ultimate demise in 2004 to the ravages of metastatic Breast Cancer. This background combined with my wife and I interacting with many different physicians cemented in my mind the need to be a competent, compulsive, compassionate and above all empathetic physician!

I was involved with the Academy of Neurology for the last 25 years and as such developed and chaired the Guidelines Committee. We were responsible for creating the standards of care for such varying condition as coma and vegetative state, brain injury (concussion and sports injury), seizure management, and the diagnosis and treatment of Multiple Sclerosis.

My practice at the Neurology Center is predominantly focused on Multiple Sclerosis as I am one of the staff physicians with the Southern California Multiple Sclerosis Center. I am rendering numerous second opinions for difficult diagnostic dilemmas, diagnosis and treatment of Multiple Sclerosis, Neuromyelitis Optica, and the diagnosis and management of the chronic conditions of brain injury and brain tumor. I am a staff physician at the Scripps Encinitas Hospital providing consultative services to the hospital staff along with the primary care for patients of the Scripps Hospital Inpatient Rehabilitation Unit. There we care for a variety of neurological problems including stroke, spinal cord and brain injury.

I consider it a privilege and an honor to be a part of the most advanced, competent, exciting and compassionate Neurological Group in Southern California.
