​The Cat Hospital​ of Tampa Bay

Diane Stephenson:  Veterinary Technician, Hospital Manager

Dr. Lee has been at The Cat Hospital of Tampa Bay since 2011.  She has always been a cat lover since she was little, and she was always the kid who brought sick stray cats home.  Over the years, the desire to be able to help the strays inspired her to pursue her goal of becoming a veterinarian!  She graduated from Florida State University with a Biology degree, and then graduated with Honors from the College of Veterinary Medicine at University of Florida in 2002.

While in veterinary school, Dr. Lee served as the President of the Student Chapter of the American Association of Feline Practitioners (AAFP), and was an advocate for promoting feline education and hands-on experience for her fellow students.  She worked closely with feline expert Dr. Levy and had published journals in the Journal of American Veterinary Medical Association.  At graduation, Dr. Lee was recognized for her excellence in feline medicine and surgery by the AAFP.

Dr. Lee was an active volunteer for Operation Catnip, a local TNR (trap-neuter-return) program for feral cats, while she was at school.  After graduation, she continues to be a volunteer of TNR program at Animal Coalition of Tampa where she also served on the Board of Directors for several years.

Dr. Lee has a strong passion for feline medicine and has worked at local feline hospitals for years.  She is a member of AAFP and AVMA.  She and her husband Jimmy have two young kids, Gracie and Aaron, and have shared their home with many cats.  They also keep a salt water fish tank to entertain the cats!  >^ ..^<

Diane has been with us since March of 2014. She brings 12 years of experience to the table and graduated from St. Petersburg College.  Her love of felines and dentistry led her to pursue a career with us. Diane is a happy, outgoing person and a joy to have at The Cat Hospital of Tampa Bay. Her calm demeanor is an asset when we have an anxious patient.

Diane and her family moved from Montego Bay, Jamaica to the St. Petersburg area when she was eight years old. She enjoys being outdoors, especially if it involves the beach.       

Diane lives with her two children Olivia and Jackson, plus her four cats: Charlie, K-Lindo, Leibe and Robyn.  The newest addition to Diane's family is Lucy, a rescue dog from the Grand Bahamas Humane Society.


Donna F. Shannon, DVM grew up in Asheville, NC, and attended Western Carolina University. She graduated from The Ohio State University College of Veterinary Medicine in 1980. She worked with mixed and small animal practices before opening her own small animal practice in 1982 in St. Johnsbury, VT.

In 1990, Dr. Shannon decided to move back to the south to pursue her dream of working with cats only, and opened a feline-only practice in Ft. Myers, FL. She relocated to the Tampa Bay area in 2002, and has worked as a small animal clinician and surgeon for several practices in the area.

Dr. Shannon opened The Cat Hospital of Tampa Bay in September, 2008, and is enjoying concentrating on cats again, and providing an environment conducive to recovery and health for her feline patients. Dr. Shannon and her 6 indoor cats live in St. Petersburg. She spends most of her free time volunteering for Pilots n Paws and Angel Flight Southeast.
