Tai chi teachers are not medical professionals and therefore are not licensed. To find a class, try your local YMCA, YWCA, or health club. Colleges, universities, and city recreation departments may also offer classes. If you'd prefer to learn tai chi one-on-one from a tai chi master, contact a martial arts school and ask for recommendations.
Don't commit to anything until you are sure the class or teacher is right for you. Observe a class or take a trial class if it is an option. Talk to the other students in the class and be sure to inquire about the instructor's background and experience.
You can also check the library or a bookstore for books and videos to supplement what you have learned in a class.
