Dr. Erik C. Spayde MD Inc he is a brilliant spine surgeon I was referred to him by other DR.'s because the previous surgery failed. I can only tell you that he is well known and respected all over So. Calif. If you, a family member or friend help with a back or neck problem you will be grateful for his vast knowledge, education & experience. My back & neck feel like they did before all of my severe degenerative arthritis started to attack from my neck to the bottom of my spine. Go online & check his Bio. From a very grateful patient who will never recommend any other spine surgeon. Patricia A. Wells
