Lelani Sanchez

Assistant Administrator

Lelani Sanchez grew up in Princeton and has many childhood memories of this beautiful area: from scaling the city plowed snowbanks that got as high as the street signs, to long summer days spent chasing beach balls on Green Lake and wandering the Princeton Flea Market with a fistful of coins. She loves to travel but she is also a passionate advocate of the “staycation”, so she is thrilled to be a part of an organization that fosters vibrant community experiences for visitors and locals alike! Lelani lives in Ripon with her husband and two children and they are always on the lookout for family friendly ways to while away the hours.
