Between my back and my neck, I've had 5 epidurals in the last two years. Today was my first with Dr. Glaser. While I was a bit apprehensive due to some prior experiences, without a doubt this was the best experience I've had with respect to both pain management and anesthesia. It's only a few hours since the epidural procedure on my neck and I'm already feeling substantially better. Dr. Glaser and his team (both at his office and at the Encino Outpatient Surgery Center (EOSC) were kind, compassionate, courteous, timely, efficient and super professional! I look forward to reclaiming my life. Thanks again Dr. Glaser!
