Kaye lives with her husband, Jeff, and two teenage daughters, along with their wonderful pets: 2 Bernese Mountain dogs, 2 cats, and a Dutch Warmblood. A resolute foodie, Kaye loves to entertain and experiment with various styles of cuisine. She and her family enjoy traveling together, and have visited Brazil, the British and US Virgin Islands, China, Croatia, France, Italy, Norway, Spain, and Germany, Holland, South Africa and much of the United States.

The Lewis family avidly supports the Julliard School of Music through a vocal scholarship set up nearly 20 years ago and has donated a vocal performance room in the renovations scheduled for completion in 2009, named the Loretta Varon Lewis Room (a noted coloratura sopranist opera singer and Jeff's mother).
