Jenn Lassa and Marcin Matlakowski met in 2008 while working as landscape professionals in Chicago. They quickly realized their shared enthusiasm for beautiful design, the outdoors, and living life to the fullest would make them perfect partners in business and in life! They decided to take their talents to the next level and launch their own business where they could devote their time and energy to designing and building outdoor spaces that inspire others and in 2009 Rooftopia was born.

A few years later in the fall of 2013, Jenn and Marcin were married in a picture-perfect farm wedding surrounded by family and friends. They have enjoyed every minute of doing the work they are passionate about and look forward to a bright future together bringing beautiful outdoor spaces to life in Chicago.
