The Gonstead Clinic of Chiropractic, completed in 1964, was the third and final clinic Dr. Gonstead would design and treat patients from in this little town of Mt. Horeb before his death in 1978. Dr. Gonstead built the largest chiropractic facility in the world. A 22,000 square foot clinic, it had a waiting room to seat over 100 patients, 11 adjusting rooms, x-ray facilities and lab, and a lower level to hold chiropractic seminars. It was to become the most renowned chiropractic facility in the world. Next to his new clinic, Dr. Gonstead added a 78 room, full service motel to accommodate the clinic's numerous long distance patients. Dr. Gonstead and his fellow staff members attended 300 to 400 patients on a daily basis. The huge following of patients led Dr. Gonstead to start the Gonstead Seminar of Chiropractic, helping to teach and develop even more Chiropractors in the art and philosophy of the Gonstead system of Chiropractic.
