Middle school is where strong students are made — or where small gaps quietly start to grow. Our tutors keep your child on track, fill those gaps before they snowball, and build the study habits and confidence that make high school far smoother.
Serving students across the Denver metro — from Cherry Creek, Littleton, and Highlands Ranch to CU Denver and local colleges.
Meet Our Denver Tutors
We fill gaps in math and reading now, so high school doesn't feel like an uphill climb.
Patient, encouraging tutors turn frustration into 'I can do this' — the mindset that lasts.
Organization, time management, and how to study — habits that pay off for years.
Friendly experts who are great with this age group — vetted for patience and clarity.
Every level — from middle school through advanced college courses.
My son went from a frustrated 9th grader getting D's on his math tests to straight A's for the next three years. He actually signed himself up for AP Calculus his senior year because he wanted to maintain his knowledge going into college.
Ari was excellent. He explained things very clearly. My daughter felt like a fog had been lifted, and she has greater confidence now.
Our daughter looks forward to her time with her tutor every week. He is a mentor, a friend, and goes the extra mile before tests to make sure she has everything she needs to feel competent and prepared.
A belated thank you to Liz for a semester of math tutoring. She essentially taught all of Algebra Honors II. My child received an A in the class and scored in the 99th percentile of the PSAT. We could not have done it without your kindness and teaching skills!
My children have loved every tutor we have used from High Performance. The tutors have helped them excel in their studies in the classroom and helped them succeed on the AP, IB, ACT, and SAT exams!
Liz is the best. Ethan learns so much with her, and we love how flexible her schedule is.
The tutors are great at explaining issues and problems that people like myself struggle with. I now enjoy math which allows me to understand and comprehend more clearly what is going on in class.
I used High Performance Tutoring over a 5-week period during my preparation for the GMAT. Despite the short timeframe, we were able to hit my target score and I got accepted to the Booth School of Business in Chicago!
Marguerite was kind, compassionate, thoughtful, and very knowledgeable. Our daughter feels she can now trust her teacher to learn the math she needs. We are thankful to have met her on our journey.
My daughter needed an AP Chemistry tutor, and they paired her with a Chemical Engineering major. She came away from her session feeling like she understood much better than before, and definitely feels more confident about chemistry!
My daughter Hannah raised her ACT score from a 26 to a 33 after completing an intensive twelve-week training program with High Performance Tutoring. This score will open up so many doors for her!
I despise math, but High Performance Tutoring helped me get an A in my medical statistics class. I was admitted to the hospital during finals week and my tutor came to my hospital room and tutored me there for our last session. He was great.
