The Best Parathyroid Surgeons in the World: Jim Norman, Deva Boone, Jamie Mitchell, Kevin Parrack, Dan Ruan, Tobias Carling, and Drew Rhodes.

The seven surgeons at the Norman Parathyroid Center have more experience with parathyroid disease and parathyroid surgery than anyone else. All of our surgeons have dedicated their surgical careers to one disease: hyperparathyroidism. All trained at the best surgical centers and all are members of all the most important societies. All have been chosen as "top doctors" and "top surgeons" numerous times. This is all we do, and we perform parathyroid surgery different than all other surgeons in the world, including the fact that every operation has at least two of the best surgeons checking each gland. No other surgeons go through the steps we take to attain the highest level of care which is why we perform about 80 parathyroid operations per week, about 10% of all in the US. Treating patients like a member of our own family is always our number 1 goal, and our promise to you. A short bio of each surgeon is below.


You Can Have the Worlds Most Experienced Parathyroid Surgeons Perform Your Parathyroid Surgery

We are the world-wide leader in parathyroid surgery. Our surgeons perform an average of 16-17 parathyroid operations per day, nearly 80 per week, about 3,900 per year, with an expected cure rate of over 99% and a complication rate near zero. Nearly 100% of patients will go home within 2 hours of their parathyroid operation. Nearly all patients will have a scar that is only 1 inch that will be nearly invisible within 6-9 months. The average operative time is 19.6 minutes with the most parathyroid operations taking between 16 and 25 minutes to evaluate all four parathyroid glands. Even patients with a negative sestamibi scan and a negative ultrasound can expect a mini-operation that takes 19 minutes on average. We perform the same mini-operation on all patients, regardless of scan results. We are unique in that we have two expert surgeons evaluate all four parathyroid glands in virutally all patients--the only way to get near 100% cure. One final note... All seven of our surgeons are fantastic, however they work in teams of two or three on all patients. We don't use surgeons in training to do your operation, you will have two or three of the world's most gifted and experienced parathyroid surgeons in your operations and taking care of you at the hospital.

    We have a parathyroid operation that we want you to watch. It is the best teaching video about the operation and everybody should watch it to understand just how simple this can be if you have an expert surgeon. The entire operation takes just less than 13 minutes to check all four parathyroid glands and remove two tumors. This was not scripted and shows exactly how we do this operation. People love this operation video; there is no blood, just lots of talking and teaching in the operating room. Click Here


Dr. James (Jim) Norman, MD, FACS, FACE

Dr James Norman of the Norman Parathyroid Center.

Dr. Jim Norman founded of the Norman Parathyroid Center in 2003, and is recognized as one of world's foremost experts on parathyroid disease and he has treated more parathyroid patients than any other doctor. For over 25 years, he has limited his surgical practice to parathyroid operations only. He developed minimally invasive parathyroid surgery in the mid 1990s, while a Professor of Surgery at the University of South Florida, and is credited with dramatically changing the way parathyroid surgery is performed. Dr. Norman trained the other surgeons at the center in their unique 4-gland, 2-surgeon mini parathyroid technique. He and his team have performed nearly 60,000 parathyroid operations. It is safe to say that there probably isn't a parathyroid problem that Dr. Norman hasn't seen and this experience is invaluable. Watch the video of Dr Norman performing a 4-gland parathyroid operation (you want your surgeon to look at all four parathyroid glands) where he removes two tumors during an operation that takes less than 13 minutes from cut to band-aid.

The Norman Parathyroid Center is dedicated to parathyroid disease only. We operate out of two large hospitals in Tampa, including within the new Parathyroid Center at Tampa General Hospital, a new wing of this large hospital dedicated to the treatment of parathyroid disease (yes, we have the top floor of a new wing of the hospital all to ourselves!). Drs Norman, Carling, Boone, Ruan, Mitchell, Parrack, and Rhodes are the only surgeons in the world that limit their practice to parathyroid disease.

And the best Thyroid Cancer Surgeon too!

Our patients are very fortunate in that Dr Gary Clayman, the world's most respected thyroid cancer surgeon, joined our staff in September, 2016. He opened the Clayman Thyroid Cancer Center within the same Institute with the Norman Parathyroid Center. Thus our parathyroid patients are afforded access to the best thyroid cancer specialists should they need it. They have a very comprehensive thyroid cancer website. We have an entire page on Thyroid Cancer in Parathyroid Patients.

*Note: The statistics on this page do not guarantee a good outcome for every patient, they simply reflect the fact that we do LOTS of parathyroid operations and our expertise allows us to have exceptional results. Our anesthesia team has done thousands. We've done thousands. BUT--Every patient is an individual and will be treated as an individual to have the best results with the lowest possibly risk and the highest possible cure rate. These excellent results also shows that we follow our patients so we always know how we are doing. We don't guess!
