How did Natalie Tessler adapt Spa Space to overcome business challenges?

"But it hasn’t always been smooth sailing for Spa Space. Tessler had to steer the business through several obstacles, including the 9/11 tragedy just three months after the spa’s grand opening, and then the Great Recession. Tessler learned to adapt her strategy by refining her target market and the services Spa Space offered. Her resiliency enabled the company to not only survive difficult economic periods, but to thrive and grow 17 years later into what the press recognizes as Chicago’s best spa. Tessler recently turned the reins over to Ilana Alberico, another entrepreneur and founder of Innovative Spa Management, a company that has been named twice to Inc. magazine’s list of fastest growing companies. When Alberico met Natalie Tessler and learned about her vision, she was inspired to invest in Spa Space. “Natalie’s vision still resonates . . . I’m inspired to champion her vision into the future.”"
