Kari Weigel

Owner of Sylvan of North Dakota

Kari started with Sylvan when it opened in July 1995. She rejoined Sylvan in June 2004. Kari spends much of her time introducing families to Sylvan, answering their questions, and matching students up with a program built just for them! In her free time she enjoys going to coffee, playing scrabble, reading, playing with her children, and spending time with her extended family.


Maren Gerhardt

Executive Director

Maren joined Sylvan in 2006. Prior to working at Sylvan, Maren earned her BS in education from the University of North Dakota and taught in the public school system for five years. With a passion for math and higher-level education, Maren has overseen the ACT and college prep programs in addition to other programs Sylvan offers. When asked why she chose Sylvan over the classroom, her answer was simple, “At Sylvan, we teach kids to love to learn!” Away from Sylvan, you will find Maren playing outdoors somewhere with her family, whether it is the mountains of Montana, the lakes of Minnesota, or out for a run somewhere in-between.
