The Norman Parathyroid Center is the leading parathyroid treatment center in the world, performing about 10% of all parathyroid surgery in the US. We are located in Tampa, Florida where hyperparathyroidism is the only disease we treat. We perform nearly 4,000 parathyroid operations annually (more than 80 per week) with a cure rate over 99% via an operation that typically lasts between 15 and 23 minutes (under 20 minutes average) to evaluate all four parathyroid glands.
