Tammy GerringerOffice Manager & Volunteer Coordinator
In April of 2017, Tammy left cold winters and her 20 year career in healthcare administration behind and moved to Punta Gorda to become a full-time Floridian. A lifelong resident of North Carolina, Tammy, along with her husband, Andy decided it was time to head south for warmer temperatures, palm trees and sunnier weather. While taking long walks down to Ponce de Leon Park and trying to figure out the next steps in her life, her path led her by the Peace River Wildlife Center. In November 2017, she began volunteering as a habitat cleaner. As luck would have it, an opportunity to move out of the animal enclosures and into the office as an administrator and volunteer coordinator presented itself in July 2018. Now healthcare administration takes on a new perspective for her as part of the PRWC team. When she is not at PRWC, she enjoys boating with Andy, keeping in touch with her four sons and binge watching BBC shows.

Kevin BartonAssistant Wildlife Rehabilitator

Although I am a proud new Peace River Wildlife Center employee, I am not new to the organization. I have had the pleasure of being their networking partner, occasional raptor re-nest volunteer, and a huge fan for my entire 23-year career in wildlife rehabilitation. Having grown up in Venice, Florida, my first exposure to wildlife rehabilitation was a group called Amber Lake Wildlife Refuge of Englewood, which was a big influence on my life. My first job in the field was at the former Pelican Man’s Bird Sanctuary of Sarasota, starting back in 1998. I worked in their hospital for 5 1/2 years, leaving as the last hospital manager and head of rehabilitation under its founder Dale Shields, “The Pelican Man”. In 2004, I co-founded the Wildlife Center of Venice, acting as executive director, as well as the state and federal fish and wildlife rehabilitation permit holder until leaving in early 2018. Currently, I work full time at Loving Care Animal Hospital of Englewood Wednesday thru Sunday and of course, you can find me at PRWC on Mondays and Tuesdays. Happy to be part of the team.

Andrew enrolled in the Veterinary Assistant program at Cape Coral Technical College where he found Peace River Wildlife Center on a class visit. He came to realize that he wanted to pursue a career in wildlife rehabilitation so that he could combine his passions of veterinary medicine and wildlife conservation. In his free time, Andrew prefers to be outdoors with activities such as camping, hiking, and canoeing. He has two dogs, Daisy Mae and Buck, that often accompany him on his adventures.

Fun fact: Andrew makes it a point to drink from at least one naturally occurring water source in every wild place he visits so that it may “become a part of him.”

Habitat Enrichment

Robert Warren Maintenance Supervisor
Robert was born in Minster, KENT, ENGLAND and joined the Royal Navy at 16, becoming a fully qualified nuclear submariner at age 17. He spent seven years in the Navy but left after meeting his soon-to-be-wife on a trip to NATO’s missile firing base off Cape Canaveral, Florida. He immigrated to Vermont, where he and his wife raised 2 children. He has had a varied career as an electrician, furnace repairman, odd job man, theatre set builder, and most important, “Mr. Mom” duties when the children were small and in grade school. Above all, Rob is a fisherman. He doesn’t mind what kind of fishing it is- ice fishing, deep-sea fishing, surf casting, from a kayak or walking through muddy brooks, looking for that rainbow trout prize!

Rob and his wife vacationed in Florida for several years before deciding to purchase a house for retirement in Punta Gorda Isles. Rob came down from Vermont and as he was getting the house ready for a rental, realized that after spending over 30 years there, the cold winters of Vermont were enough. Okay, it was REALLY his wife who wanted to move here full time, but being an amenable soul, Rob agreed to move. They have been here since February 2019. Rob began volunteering at PRWC in February and has become very fond of the inhabitants.

Fun Fact: He is an awesome cook- he loves to bake cookies and makes wonderful caramels, truffles and other treats for Christmas. You will consider yourself lucky if you get to taste them!
