I have been seeing Dr. Geller for a couple years now, and he has definetly helped me with my chronic back and neck pain through nerve block and trigger point injections. Although the pain has not gone away completely I can function at a much higher level because of his care. In addition, he is overly concerned that none of his patients abuse or become addicted to any pain medications. This is a great trait to have when dealing with somethng that has the potential for abuse. The only downside is his office is not the most appealing or clean environment. If you can get by that, you will be cared for by a most competent and knowledgeable doctor. He knows pain management, and prescription drugs better than most doctors you will come in contact with through his extensive education and ongoing research.
