There is no certification or licensing for practitioners of guided imagery, although many professionals who practice it are licensed in other areas of health care, such as psychiatry and psychology. Many psychotherapists, nurses, physical therapists, and hypnotists also offer guided imagery training. The best way to find a reputable practitioner is to seek referrals from your primary-care physician and friends you trust. Ask for references and check them. Be sure you feel comfortable with a practitioner's style before you begin to work together.
If you'd rather learn guided imagery on your own, look for a class at a local hospital, wellness center, or community center. Guided imagery tapes that help visualization are also widely available.
