The most important factor when choosing a ketamine provider is experience and the doctor's commitment to providing safe, compassionate care. Ketamine infusion therapy is a relatively new breakthrough in depression and chronic pain treatment, and you will need a doctor who thoroughly understands the procedure, practices with care and integrity, and has a long track record of successful outcomes. We have treated nearly 2,400 patients in our New York City office alone; the largest individual practice in the world. Dr. Brooks himself is involved with every patient's assessment and treatment. We understand your problem and want to help.
