Jill Spangenberg
Global Director of Retail, SPORTIME Clubs

Jill has led teams and built the business for a variety of specialty retailers throughout her career. From a strong apparel background, including Kenneth Cole, Jacadi, and Hot Topic, she moved into hard lines with Yankee Candle. After 10 years of moving the business forward at Yankee and Newell Brands, it was time for a new challenge. Jill is looking forward to building teams in our Pro Shops that serve as ambassadors for the SPORTIME and JMTA brands. Jill lives in Oyster Bay, NY and will be ensuring we exceed our players and members needs in all of our locations. She is also very much looking forward to tuning up her tennis game in the fall, and seeing what the sport of pickleball has to offer!
