Mark Reinhart

Co-Founder & Chief Operating Officer


Hello everyone! I have been an educator for 22 years. I practiced as a paraprofessional, public school teacher, and university professor. I believe in alternatives for training educators and behavior technicians in order to offer a variety of pathways for diverse learners. Mark and I were both raised in rural North Dakota, as well as have children attending rural school. We understand the unique needs of training and retaining educators, in addition to meeting the community’s behavioral health needs.

Hello! I have had many life experiences from farming and ranching full time for 26 years to parenting, which have led me to this chapter with Certification Central. As a continuous learner, I am committed to creating training opportunities for those who learn differently and for those who have busy lives and are longing for a lane change in life. I have a desire to open opportunities for those living in rural and remote areas. Katherine and I want to help reduce the teacher shortage in these areas while making a career in teaching affordable by reducing the financial burden of school loans.

Clinical Director and Curriculum Review Committee


Certification Central is by far the most innovative alternative training program I have seen. The extensiveness of training options meets the needs of any school or person looking to become certified as a teacher or behavior technician. Two of the program’s top qualities are its affordability and self-paced format. In addition, the program uses highly qualified instructors and coaches/advisors and has a competency-based curriculum that ensures students will complete the program with the knowledge and skills most important for success in the field. I cannot say enough good things about this program…wish I had thought of it!

Jennifer Sateren

Special Education Technician Program Director


I have been a teacher for 19 years, 13 years in special education and 5 years in general education. I have taught students of all ages, from Kindergarten to 12th grade. After receiving my undergraduate degree from MSU-Moorhead, I spent 3 years as a special education teacher in the Minneapolis/St. Paul area. I moved back to North Dakota and continued teaching special education at Tate Topa Tribal School in Fort Totten, while earning my Master’s in Special Education from UND- Grand Forks. For the past 5 years, I have been working closer to home at Dakota Prairie Elementary School in McVille. Currently, I am a 1st grade teacher at DPE. I feel fortunate to have worked as both a special education and general education teacher. My hobbies include spending time with my family, driving my two daughters to dance classes, and reading.
