Kianna “Kiki”

“Kiki” has been an integral part of Seahorse Swim School for over 15 years. She has taught hundreds (maybe thousands) of kids to swim with Seahorse Swim School and Kiki is a pro with infants and young children. Calm, delightful and encouraging are words used to describe her teaching style. Kiki works on Saturday mornings and is our baby whisperer– able to connect with all children and get them happily to join in on the fun. She sings, she teaches.. and she is a favorite of many of our swimmers. Everyone loves Kiki!
