  • “It's crucial that our back-office accounting and payroll are accurate and compliant, and Harness has been a fantastic partner in making that happen. They truly understand the unique compliance and reporting needs we face, and they've kept us audit-ready every step of the way. Their team is knowledgeable, reliable, and always quick to answer our questions. It’s been a huge relief having experts we trust handling such an important part of our operation.”


    ~Ana Andres, HR and Accounting Coordinator, Odyssey Charter Schools

  • “Carrie turned what could have been an existential crisis for our school into a positive, making our school so much stronger in the long term. It is no understatement that without Carrie's level of financial knowledge, practical advice and genuine desire to see our school succeed in difficult times that we would not be here today... 18 years later we are thriving as a direct result of her very clear, very sound fiscal advice!”

    ~Dr. Sharon Weir, Principal/Executive Director, New West Charter School

  • "HARNESS performs all of our accounting and finance functions for my organization and has significantly reduced staff time spent on fiscal operations.  We highly recommend them to any organization looking for more efficiency.  We have been extremely happy with all of the staff we work with and love the technology they use to streamline processes."

    ~Carlos Garcia Saldan, Executive Director, Odyssey Charter Schools

  • "When I stepped into the CEO role to turn around ICEF Public Schools, Carrie played a crucial role in my success. She closed six months of books in just four weeks using a different accounting system than she was accustomed to. Her work gave me the accurate financial picture I needed to make critical decisions that ensured the school's survival. Carrie remained a trusted partner throughout, and I am forever grateful for her expertise and dedication."

    ~Parker Hudnut, former CEO, ICEF Public Schools

  • “I have known Carrie for over a decade and worked with her while she was at ExED and at GALS. I have always found her to be extremely responsive and thorough. I believe working with Carrie would be a positive experience for any charter school looking for quality service. If I were not enjoying my retirement, I would love to work with her again myself.”
