About Marisa

Marisa, who spent 20 years dancing professionally, designs her clothing to stand up to hours and hours of hard work and sweat. At the same time, her pieces showcase the toned, strong, beautiful bodies of women who value the benefits of that hard work and sweat.

"When I was dancing professionally, it was hard to find the right combination of beauty and great construction. That’s why I started making my own clothing".

The ByMarisa line is dedicated to the daily needs of dancers, and is designed to work hard and look flawless, just like dancers.  Marisa relocated the headquarters from New York City to the Lehigh Valley, and as she grew her company to include SteelCore activewear and SteelCore Planet organic and sustainable products, she developed local partnerships to source and manufacture her high quality lines of clothing.
