Joining a local chapter of the Piano Technicians Guild (PTG) offers the piano technician a way of being a part of a group of like minded persons, all interested in the furtherment of the trade. Chapter membership encourages professional relationships with other students of piano technology and those who are already accomplished technicians. Local chapters hold monthly meetings to discuss relevant topics, hold training classes and seminars and provide access to other inmportant PTG events such as annual National Conventions. Two excellent chapters in the Chicago Metropolitan area are the Chicago and North Shore Chapters.
