Nanum Gaack, Kevin Clevenger, is a carver, singer, and dance group leader of the Su Laxgayna (New Path Dancers). Clevenger apprenticed under his uncle Wayne Hewson and is now the lead carver at the Carver's Shed at the Rainforest Sanctuary in Ketchikan. He has served on the Totem Heritage Center Advisory Committee since 2015 and began teaching at the Totem Heritage Center in 2024. His classes have included drum making and design.

This drum is made of deer hide stretched over a wood rim and held with sinew. The drum is painted with the "Four Clans" design, created by Clevenger to represent the four Tsimshian clans: Eagle, Raven, Wolf, and Killer Whale. This drum and drumstick were created when Clevenger taught the Drum Making and Design class in 2024. Students made drums, created a formline design, and hand painted their drums. On the final night of class, Clevenger sang the Four Clans Song so students could bring life into their drums.

"I taught a drum making class at the Totem Heritage Center. It was such a great experience and was a wonderful group of adults to work with. My uncle Wayne Hewson would always tell me that I needed to start teaching and I've been too nervous. I'm so glad I started and would just think 'what would Wayne do?' during class."
