Tina Wallace, Controller

Tina joined TES at the company's inception and was instrumental in the turn-around work needed to establish cash management systems and forecasting.  Tina started her school accounting career spending five years with a Colorado school district.  She then moved on to charter schools where her skillsets provided results on a grander scale.  Tina is not your conventional school accountant, simply reporting historical events.  She works with the school leaders and/or business managers to ensure fiscally sound operations across all programs and funds.  While you don't always like what Tina has to say she makes fiscal freedom a reality.


Sammy Hansen, Operations

Sammy joined the TES team in 2017 and oversees all human resources and school operations. Her background is in the staffing industry working for fortune 500 companies providing recruiting and human resource services.  Sammy has set TES’s customer service bar high, and strives to make sure all school staff have access to the resources they need.

Sammy holds a Bachelors of Arts in Anthropology and Psychology from the University of Oregon


Carol Hansen, Chief Executive Officer

Public finance expert, Tatonka Capital Corporation and Tatonka Education Services CEO, Carol Hansen, is a thoughtful, unflappable and tenacious CEO.  

Hansen founded TES, in 2015, when presented with a workout challenge involving a failed charter school management company and the possibility of closing its charter schools.  Hansen and the senior management team’s actions successfully worked to keep from closing affected schools - leaving staff and students out in the cold.   Over a two-year period TES took its managed schools from insolvency and low academic scores to financial stability and growing academic success

Hansen is an active participant in YPO at the local and international levels of the organization.  She has been awarded two of YPO’s top international honors for her leadership.  Carol served as an Advisor to Sheryl Sandberg and the Lean In Launch Team, which today supports 35,000 Lean In Circles.  She is also active in other philanthropic and trade organizations.

A favorite quote explains Carol knows how lucky she is that an observer cannot tell if she is working … or playing. (Quote attributed to the Chinese Taoist philosopher Lao-Tzu)
