Hello! I live in Wake Forest, have a middle schooler, and am a real estate broker in the area. There are quite a few swim teams in the area, swimming is quite a popular sport among the local kids! You can join a swim team in your neighborhood: examples of these are Heritage Wake Forest, Granite Falls (Rolesville), Wakefield. Most larger neighborhoods that have a community pool will also have a swim team.
If your kids are looking for something more competitive and year-round, YMCA of the Triangle has a branch in Wake Forest, Kerr YMCA, and they host the YOTA swim team. You can check them out at yota.ymcatriangle.org. There are also private swim clubs in the Triangle but they are further from Wake Forest.
If you have further questions or would like more specific info, please feel free to email me at firstname.lastname@example.org.
Good luck on your move to our beautiful area!!
