Native born to Northeast Ohio, Debbie earned her BA in psychology and sociology from Mount Vernon Nazarene College. Debbie holds an Ohio teaching certificate as well. She worked in the mental health field for some time until she discovered the Montessori philosophy through her sister.

After both taking her training at MISD and having the unique privilege of working in their toddler community, Debbie finished her Montessori training and took a job in Northern Virginia where she lived and worked for 4 years. Jumping at the chance to be involved in the beginnings of a public charter school in Northeast Ohio was the perfect opportunity to return home.
