Administration Team

Dana Stempil Herzberg, M.Ed.
Dana Stempil Herzberg, M.Ed.Founder, Head of School
With degrees in Special Education, Curriculum and Instruction, and more than 20 years in the education industry, Dana is well known in the Phoenix/Scottsdale area for her work with students who have learning differences, ADD/ADHD, and twice exceptionalities (giftedness in addition to learning difficulties). Dana was able to overcome her own learning challenges in school, thanks in large part to several exceptional teachers and tutors. In 1999, she founded On-Track Tutoring in order to provide children of all abilities the same high-quality educational services that she had received. Over time, the need for a small, nurturing, and supportive learning environment for high-potential children with attention and learning challenges became increasingly more apparent. In order to help fill that unmet need, Dana began JGS (then called On-Track Academy) in 2010, specifically designed for students who learn differently.
Jessica Wilhelmsen, BA
Jessica Wilhelmsen, BAChief Financial Officer
When Jessica started with us in 2012, we immediately questioned how we had ever managed without her! She has brought a plethora of skills and insight to our team and, in fact, we are nearly certain that there isn’t anything that Jessica can’t do. An ASU graduate with a bachelor’s (Magna Cum Laude) in Psychology and an interest in School Psychology, Jessica spent several years volunteering and working in the nonprofit world, focusing on the social and emotional development of youth. She is the “behind the scenes machine” who makes everything happen: Jessica manages our online parent portal, facilitates events, assists with testing and assessments, and heads the school’s accounting and finance team. Beyond her endless skill sets, Jessica is an essential (and adored!) part of our team.
Shari Schwartz, BFA
Shari Schwartz, BFAChief Operations Officer
In 2006, Shari joined the On-Track Tutoring team and has since been invaluable in helping facilitate the growth of OTT and JGS, sharing Dana’s passion for education and kids (especially those who don’t necessarily fit into “perfect” molds!). A graduate of the U of A’s visual communications program, Shari has extensive experience not only in graphic design and communications, but also in small business management and development, human resources, public relations, and marketing. Shari has also spent much of her personal and professional life working with kids in various capacities, from being a camp counselor, to teaching art at the Boys & Girls Clubs and in private school settings, to tutoring students in literacy. Shari, along with Jessica, is key to making sure all the “parts” of JGS are working behind the scenes!
Kim Hogan
Kim HoganOffice and Facilites Manager, HR Representative
Kim spent much of her early career in human resources before making the decision to leave the workforce to spend more time with her family. During her hiatus, Kim enjoyed volunteering at each of her children’s schools (3-4 days each week!). Loving the school atmosphere and the flexibility to work the same hours as her kids, Kim accepted a position as a paraprofessional where she remained for the 5 years prior to joining us at JGS in 2015. In addition, Kim worked for 8 years side-by-side with the director of a local day camp where parents and campers affectionately referred to her as “Mama Kim.” Always at the top of her game, Kim helps ensure that JGS is a well-oiled machine. It’s hard to imagine how we ever managed without her!
