    We had a very positive experience with Alissa as a tutor for our pod of 5th grade boys from January - June 2020. She cared a lot about the boys and worked hard to create meaningful activities for them. The pod experience was invaluable … More for all of our families during a difficult year and we were so grateful to have found this partnership! We also want to appreciate Craig for helping to match us with a tutor on very short notice after we had cycled through a few folks who were not able to see the commitment through. Thanks for sticking with us!

We are also thankful that Craig at Themba Tutors really "gets it" and partnered us with such a wonderful tutor who was a great fit for our girl.
  • Avatar Nicole May ★★★★★ 3 years ago

    Our son started in a new high school, 100% remote, and was really struggling with Latin and Physics. I found Themba Tudors online and had an initial call with Craig, who was very knowledgeable, responsive, and found 2 amazing tutors for … More us. Both the Latin and the physics tutors were fantastic, connected with my son really well and helped him go from 'failing' grade to 'honors'! I will for sure continue using (and recommending!) Themba Tutors. Thank you, C, K, and W!

  • Avatar Christine Gennetti ★★★★★ 3 years ago
    As an adult student diagnosed with a learning disability during grad school, I knew I needed help dealing with my Master's program's demanding workload. I was seriously considering dropping out when I was referred to Themba Tutors. … More I was paired up with a wonderful tutor, Julie, who was a total lifesaver. I learned many techniques that I can utilize in the future as I embark on the next phase of my career.
    I can wholeheartedly say after working with Themba for two years that I would not have finished my program without this organization. And I am so thankful I selected them.
  • Avatar Fabiola FITZPATRICK ★★★★★ 4 years ago
    We were introduced to a wonderful tutor: Mcedwyn. He and our son, a freshman in college, worked well together. As a result, our son’s grades significantly improved. The tutor taught our son subject content and various methods to effectively … More study for quizzes and exams. Our son was also taught time management and organization. My son’s experience with the tutor made the first year of college a less intimidating experience.
  • Avatar Jude Eugene ★★★★★ 3 years ago
    We have been with our tutor, Cailin Schiller, for two years, from 5th - 7th grade. She started as an executive functioning tutor with my daughter. From the start, she demonstrated a depth of expertise and a selective use of techniques skillfully … More adapted to my daughter’s ADHD and Math disability. Cailin made Math accessible and understandable to her in a way that even her teachers had not been able to do. She differentiated reading, writing and math tasks and assignments to tailor them to my daughter’s unique learning differences. Not only did it have an effect on her grades and her work efficiency, but she finally could do her work with less anxiety. Even my daughter’s teachers used Cailin’s guidance to modify their work with her. But most importantly, she became my daughter’s favorite resource. I can’t say how invaluable Cailin has been to my daughter’s progress and well-being. I’d recommend her a million times over. She is a gem.

    We were very lucky to have found Edwouine Swift, my son's therapist through Themba Tutors. Thomas is 12 years old, and it is extremely difficult to get him to write. Edwouine just works her magic with him, he adores her and is so … More eager to follow her guidance. I have no doubt she will be a positive driving force in his academic future.

Navigating trigonometry in NYC high schools can feel overwhelming as students encounter identities, unit circle mastery, radians, inverse functions, and multi-step proofs under intense academic pressure. This can result in lower grades and diminished confidence in math, creating a cycle of frustration and math anxiety .

We place a strong emphasis on task initiation, teaching students how to approach and begin complex, multi-step trigonometry problems without the typical “freeze” that comes from math-related anxiety.

TESTIMONIALS

This company is great at finding awesome learning specialists who work with kids of all ages and use multisensory techniques to help break down abstract concepts. My child needs help with math, and they supplied my child with a top-notch math tutor who could help my son improve. Not only is it hard to find qualified math learning specialists who work well with school-aged children, but they also come to your home, which is a real godsend.

 

-Mr. K. Kim 

Ethan was very happy with the sessions, and I could see his increased confidence in Math classes at school. Ethan’s grades were generally improved in his IB maths assessments, and his MAP percentile ranking increased from 78 to 87%. During this time, Ethan missed 2 of his 5 school Math classes each week for tennis training. Sam provided the math support we needed at home to cover the curriculum but also worked well to fill gaps in his knowledge from previous years.

 

-Caroline B.

Thank you for the wonderful math tutoring you did with V! We can see the changes in her self-confidence. It has been encouraging to see her improving her math grades. She is a big fan of yours, and we are, too. Because of how LaGuardia HS structures classes for the year, V’s math class has ended. Regardless, we will want Gillian to tutor V again when math officially starts up again in the fall.

 

-J.G.

My child worked with Gillian D. virtually for math enrichment. She is an excellent teacher. She took time to understand my child’s specific learning style and provided engaging tools. She was kind and empathetic—she made it her goal to connect with my child and build trust and rapport. Thanks to Gillian, my child started the school year confidently and without the typical “brain drain” that occurs over the summer.
