Proven Results

Percent of Students Meeting or Exceeting State Standards


After working with the teachers of New Heights Charter School, a small K-8 school serving underprivileged youth in 

South Central Los Angeles, we immediately began to see increasing numbers of students meeting or exceeding state standards on the California Assessment of Student Performance and Progress (CAASP). 

Finding Success


New Heights Charter School is now ranked as one of the


Underserved Students in Math! 

Research Based Instruction


We now know what works.  There is not a "one size fits all" approach, but rather, a tailored approach to math instruction.  Teachers learn how to read the kids and have the tools to most effectively move them along their learning journey.


Kelly, HS Math Teacher

 Working with Diana has made me fall back in love with teaching. She’s inspiring, understanding, willing to help and a person you’re willing to take a risk for.  She’s come to our district when we really needed some clarity and helped to be a liaison between our Math teachers needs and our districts wants and expectations.  I have finished off this school year with students achieving phenomenal results but most importantly having fun doing it! 

Sarah, Grade 6 Math Teacher

 Diana has completely transformed the way I teach math and, even after four years of working together, always manages to find ways to enrich my teaching and help me grow as an educator. I genuinely look forward to hearing her feedback and insights and have never once felt criticized or judged - in fact, I've enjoyed the process of collaborating on new ideas to implement in my classroom and celebrating our mistakes together along the way.  I consider myself lucky beyond measure to work alongside Diana and contribute much of my success as a math teacher to her dedication and investment in me and my ongoing growth.  

Chris, Principal

 Diana has provided instructional support and recommended curricular modifications for our Math team over the past two years.  She is an incredible resource and worked diligently to help us establish goals and improve student outcomes.  The results speak for themselves.  We have seen some promising gains based on her efforts with individual coaching and employing data to inform instruction. 

Louise, Director of Mathematics

Diana Kolhoff created some productive discourse with our teachers. The work on growth mindset with our teachers has transformed the beginning of the year discussions that they have with students. She is a true professional who will stop at nothing to advocate for what is appropriate for a child's mathematics education. 

Christine, Director for Curriculum and Instruction

Ms. Kolhoff has outstanding relationship skills and has developed strong relationships with teachers, principals, and district administrators.  During professional development sessions, Ms. Kolhoff presents information in an organized manner and she is well prepared for her sessions.  She attends many workshops to enhance her own knowledge and share this new information with our teachers. I am always impressed with her dedication and professionalism.

Amy, Principal

 Diana has been coaching the teachers at our school for 5 Years. Our teachers love working with Diana because her math content knowledge is so strong, her coaching approach is supportive, and she is always bringing us new research to inform our learning. Also...our math scores have steadily increased each year we work with her!
