Hello! I am so excited to be returning to Marrama as a 4th grade teacher for a second year. I began my journey at Marrama as an ECE paraprofessional. I have a Bachelor of Arts in Psychology as well as a second Bachelor of Arts in French and German. I also have a Master of Arts in Teaching. My knowledge of two languages other than English helps me understand what it is like to learn a second language. I look forward to working with my parents and students this year.

My name is Leslie Wollenweber and I was born and raised right here in Denver, Colorado. I went through the Denver Public School system and got my undergraduate degree and masters at the University of Colorado at Denver. I have been at Marrama for a long time! I am looking forward to a wonderful year in 4th grade.

I am born and raised in Colorado, and am happy to have moved back from being out-of-state for college. I recently graduated from the University of Missouri with a degree in Elementary Education. I am very excited for my first year teaching, and am proud to be a Marrama Mustang!

 Hi! My name is Ashley Martin. I’ve lived in Colorado since I was six months old so I consider myself a native 😉 I graduated from the University of Northern Colorado with my Elementary Education license and an endorsement in English Language Acquisition (ELA). When I’m not working I enjoy doing all things Colorado (skiing, hiking, biking, rock climbing, paddle boarding, and camping). This will be my fourth year in DPS, but my first year at Marrama and my first year as the classroom teacher. I’m excited to start my career in such an inviting school as part of the Marrama family.
