Kimberly Law, MD, Chief Resident

Email Dr. Law

I grew up in Orlando, Florida, and I moved to Tampa in 2005 to attend the University of South Florida. I loved Tampa and USF so much, that I wanted to stay here for medical school, Residency, and now chief year! During medical school, I learned to love how much USF Pediatrics could offer with their affiliations with All Children’s Hospital and Tampa General Hospital, and I just knew I wanted to be a Pediatrician here! On my days off, I enjoy traveling, spending time with my family, being out on the water, walking on Bayshore, going to Pure barre, shopping, cooking, baking, and trying delicious restaurants around Tampa! I also love coming home to my wonderful husband, 2 silly pups (a Cavalier King Charles Spaniel and a rescue mix), and a kitten who have all supported me through my journey!
