I am in Florida as well. I would recommend Tampa and Lutz Florida in specializing with J-pouches. Unfortunately, a lot of doctors are not J-pouch educated and we tend to have to travel to other cities/states to get the care we need. Its not fair but its apart of the J-pouch journey.
Dr. Jennifer Seminerio is a IBD and Pouch specialist and she currently works at the USF IBD center but she is moving close to Orlando. I am not sure how far that is from St. petersburg but I think she would be a good candidate for you if you do not want to drive to Tampa or Lutz.
